Microsoft SCAM Solved

I went to  fix a computer from a customer in Erie, Colorado who got scammed from someone that took over their computer on remote access saying they were from Microsoft.

Microsoft SCAM Erie, Colorado

I traced the steps.Very interesting what they did they use the command prompt to put fake commands in saying that hackers were infiltrating your system and they needed to pay money to fix the issue. They said they were from Microsoft and need to fix the problems created by the hackers.

There are no hackers they put fake messages in certain places where you check the system for errors. Here’s a printout of the Windows command prompt with  bogus information

People who are not technicians are fooled by this. but this is a command prompt this is not a error screen. That’s why it says it’s an unrecognized command Copying and pasting bogus error information in the command prompt you supposed to only be typing commands People get confused by this who don’t know about computers.

Saying that you must  install Microsoft services at $1.54 a piece 198 times for each service. Then they take the credit card information charge your credit card for that and God knows for what else. They also did other things working very fast having the customer do things on the computer to distract your attention and having a lot of pop-up screens. While taking over the computer with remote access.

Microsoft SCAM Fixed Erie Colorado

I was able to undo any damage they caused and get the computer back up and running like before.  So in the end I fixed the issue.  But people need to call Computer Physicians if they get a problem with their computer so that they don’t cause more issues or problems.  This hacker could have done worse if the customer did not call Longmont Computer Physicians to come solve the issue.

Computer Repair Windows update in Longmont, Boulder, CO

Our Longmont Computer Physicians, LLC office computer had an interesting issue recently I thought I would share:

After an automatic installing of windows 10 update for Valentine’s Day Feb 14, 2018 (KB4074588) my USB keyboard on my desktop computer would no longer work. I tried 3 different USB keyboards  – none worked.  So I went into device manager to uninstall, reinstall, and update the keyboard drivers.  That did not work. So then I uninstalled the windows update.  This fixed the problem, but the update would try to install again the next time I reboot.   So I set the windows update to never install hardware drivers during the update in (system properties) I would need to choose what driver update I want manually from now on.

Here is a good article about the history of computers by marygrove.edu

History of the Computer

The history of the computer can be divided into six generations each of which was
marked by critical conceptual advances.
The Mechanical Era (1623-1945)
The idea of using machines to solve mathematical problems can be traced at least as
far back as the early 17th century, to mathematicians who designed and implemented
calculators that were capable of addition, subtraction, multiplication, and division.
Among the earliest of these was Gottfried Wilhelm Leibniz (1646-1716), German
philosopher and co-founder (with Newton) of the calculus. Leibniz proposed the idea
that mechanical calculators (as opposed to humans doing arithmetic) would function
fastest and most accurately using a base-two, that is, binary system.
Leibniz actually built a digital calculator and presented it to the scientific authorities
in Paris and London in 1673. His other great contribution to the development of the
modern computer was the insight that any proposition that could be expressed
logically could also be expressed as a calculation, “a general method by which all the
truths of the reason would be reduced to a kind of calculation” (Goldstine 1972).
Inherent in the argument is the principle that binary arithmetic and logic were in some
sense indistinguishable: zeroes and ones could as well be made to represent positive
and negative or true and false. In modern times this would result in the understanding
that computers were at the same time calculators and logic machines.
The first multi-purpose, i.e. programmable, computing device was probably Charles
Babbage’s Difference Engine, which was begun in 1823 but never completed. A more
ambitious machine was the Analytical Engine. It was designed in 1842, but
unfortunately it also was only partially completed by Babbage.
That the modern computer was actually capable of doing something other than
numerical calculations is probably to the credit of George Boole (1815-1864), to
whom Babbage, and his successors, were in deep debt. By showing that formal logic
could be reduced to an equation whose results could only be zero or one, he made it
possible for binary calculators to function as logic machines (Goldstine 1972).
First Generation Electronic Computers (1937–1953)
Three machines have been promoted at various times as the first electronic computers.
These machines used electronic switches, in the form of vacuum tubes, instead of
electromechanical relays. Electronic components had one major benefit, however:
they could “open” and “close” about 1,000 times faster than mechanical switches.
A second early electronic machine was Colossus, designed by Alan Turing for the
British military in 1943. This machine played an important role in breaking codes
used by the German army in World War II. Turing’s main contribution to the field of
computer science was the idea of the “Turing machine,” a mathematical formalism,
indebted to George Boole, concerning computable functions.
The machine could be envisioned as a binary calculator with a read/write head
inscribing the equivalent of zeroes and ones on a movable and indefinitely long tape.
2
The Turing machine held the far-reaching promise that any problem that could be
calculated could be calculated with such an “automaton,” and, picking up from
Leibniz, that any proposition that could be expressed logically could, likewise, be
expressed by such an “automaton.”
The first general purpose programmable electronic computer was the Electronic
Numerical Integrator and Computer (ENIAC), built by J. Presper Eckert and John V.
Mauchly at the University of Pennsylvania. The machine wasn’t completed until 1945,
but then it was used extensively for calculations during the design of the hydrogen
bomb.
The successor of the ENIAC, the EDVAC project was significant as an example of
the power of interdisciplinary projects that characterize modern computational science.
By recognizing that functions, in the form of a sequence of instructions for a
computer, can be encoded as numbers, the EDVAC group knew the instructions could
be stored in the computer’s memory along with numerical data (a “von Neumann
Machine”).
The notion of using numbers to represent functions was a key step used by Gödel in
his incompleteness theorem in 1937, work with which von Neumann, as a logician,
was quite familiar. Von Neumann’s own role in the development of the modern digital
computer is profound and complex, having as much to do with brilliant administrative
leadership as with his foundation insight that the instructions for dealing with data,
that is, programming, and the data themselves, were both expressible in binary terms
to the computer, and in that sense indistinguishable one from the other. It is that
insight which laid the basis for the “von Neumann machine,” which remains the
principal architecture for most actual computers manufactured today.
Second Generation Computers (1954–1962)
The second generation saw several important developments at all levels of computer
system design, from the technology used to build the basic circuits to the
programming languages used to write scientific applications.
Memory technology was based on magnetic cores which could be accessed in random
order, as opposed to mercury delay lines, in which data was stored as an acoustic
wave that passed sequentially through the medium and could be accessed only when
the data moved by the I/O interface.
During this second generation many high level programming languages were
introduced, including FORTRAN (1956), ALGOL (1958), and COBOL (1959).
Important commercial machines of this era include the IBM 704 and its successors,
the 709 and 7094. The latter introduced I/O processors for better throughput between
I/O devices and main memory.
Third Generation Computers (1963–1972)
The third generation brought huge gains in computational power. Innovations in this
era include the use of integrated circuits, or ICs (semiconductor devices with several
transistors built into one physical component), semiconductor memories starting to be
used instead of magnetic cores, microprogramming as a technique for efficiently
designing complex processors, the coming of age of pipelining and other forms of
3
parallel processing, and the introduction of operating systems and time-sharing.
Fourth Generation Computers (1972–1984)
The next generation of computer systems saw the use of large scale integration (LSI —
1000 devices per chip) and very large scale integration (VLSI — 100,000 devices per
chip) in the construction of computing elements. At this scale entire processors will fit
onto a single chip, and for simple systems the entire computer (processor, main
memory, and I/O controllers) can fit on one chip. Gate delays dropped to about 1ns
per gate.
Two important events marked the early part of the third generation: the development
of the C programming language and the UNIX operating system, both at Bell Labs. In
1972, Dennis Ritchie, seeking to meet the design goals of CPL and generalize
Thompson’s B, developed the C language.
Fifth Generation Computers (1984–1990)
The development of the next generation of computer systems is characterized mainly
by the acceptance of parallel processing. The fifth generation saw the introduction of
machines with hundreds of processors that could all be working on different parts of a
single program. The scale of integration in semiconductors continued at an incredible
pace — by 1990 it was possible to build chips with a million components — and
semiconductor memories became standard on all computers.
Sixth Generation Computers (1990–)
Many of the developments in computer systems since 1990 reflect gradual
improvements over established systems, and thus it is hard to claim they represent a
transition to a new “generation”, but other developments will prove to be significant
changes.
One of the most dramatic changes in the sixth generation will be the explosive growth
of wide area networking. Network bandwidth has expanded tremendously in the last
few years and will continue to improve for the next several years.

technology buzzword in the 1990s, and many processors used
in the enterprise business segment were RISC-based.

18. What is Intel Pentium?
The Intel Pentium is a series of microprocessors first
developed by the Intel Corporation. These types of processors
have been found in many personal computers since 1993.

19. Any difference between Pentium III and IV.
There have been a number of Pentium processor lines starting
with the base Pentium in 1993.The of the recent Pentium
entries are Pentium III and Pentium 4.
a. In a Pentium III processor, the bus speed is generally 133
MHz (although there were a few with 100 MHz). The lowest
bus speed on a Pentium IV is 400 MHz, and there are versions
with much higher speeds (topping at 1066 MHz for the
“extreme edition”).
b. The Pentium 4s are smaller than the Pentium IIIs

Scorecard reports it has an L2 cache of 1MB (1024kb), a
potential 3.0 GHz clock speed and runs at about 1.4V. The
lowest performing Pentium 4 processor, the Willamette, has

an L2 cache of 256kb, a potential 2.0 GHz clock speed and
runs at about 1.7V.

21. What is Hyper Threading? What is the use of it?
A thread of execution, or simply a “thread,” is one series of
instructions sent to the CPU. Hyper-threading is a technology
developed to help make better use of spare processing cycles.
Hyper-threaded processors have a duplicate set of registers,
small spaces of high-speed memory storage used to hold the
data that is currently needed to execute a thread. When a CPU
core is delayed, waiting for data to be retrieved from another
place in memory, it can use these duplicate registers to spend
the spare computation cycles executing a different thread. The
second set of registers will be pre-loaded with the data needed
to execute the second thread, so the CPU core can begin work
immediately

22. What is Intel Atom processor?
The Intel Atom family of processors are extremely small
central processing units (CPU. found mostly in ultraportable
devices, such as netbooks, cell phones and tablet PCs,
according to Intel. While small and light on energy use, Atom

will also improved.

40. What are the different types of RAM?
SRAM, DRAM, VRAM, SGRAM, DDR-SDRAM etc….

41. Differentiate SRAM and DRAM.
SRAM
Static RAM stores each bit of data on six metal oxide

semiconductor field effect transistors, or MOSFETs. SRAM is
used in devices that require the fastest possible data access
without requiring a high capacity. Some examples are CPU
caches and buses, hard drive and router buffers and printers.
DRAM
Dynamic RAM stores data using a paired transistor and
capacitor for each bit of data. Capacitors constantly leak
electricity, which requires the memory controller to refresh the
DRAM several times a second to maintain the data.

42. What are the different DRAM types?
FPMDRAM, EDO DRAM, SDRAM, RDRAM, DDR-SDRAM

43. What is the difference between DDR-I and DDR-II?
DDR2 is the successor to DDR RAM. DDR 2 incorporates
several technological upgrades to computer system memory,
as well as an enhanced data rate.DDR 2 is capable of achieving
twice the data transfer rate of DDR-I memory because of its
higher clock speed. It operates at a lower voltage than DDR-I
as well: 1.8 volts instead of 2.5.

44. Which is the latest DDR version? Which processor of Intel
will support it?
The latest DDR version is DDR-III. Intel’s all latest processors
such as Core i3,i5 and i7 will support it.

45. What are VRAM and SGRAM?
VRAM is Video Random Access Memory. Video adapter or
video system uses VRAM. VRAM is dual ported. It is costly.
But SGRAM is not dual ported and not costly. It is a less
expensive approach to graphics functions. Most commonly all
low cost graphics cards are using it.

46. What is SODIMM memory module?
Small outline dual in-line memory module (SODIMM or
SO-DIMM. is a type of random access memory (RAM). It is a
smaller version of a dual in-line memory module (DIMM).It is
the type of the memory module can be used in laptop.

47. Which is the memory packaging suitable for a sub-note
book system?

Micro DIMM

48. What is ECC/EPP?
EPP/ECP (Enhanced Parallel Port/Enhanced Capability Port.
is a standard signaling method for bi-directional parallel
communication between a computer and peripheral devices
that offers the potential for much higher rates of data transfer
than the original parallel signaling methods. EPP is for
non-printer peripherals. ECP is for printers and scanners.
EPP/ECP is part of IEEE Standard 1284.

49. What is over clocking?
Over clocking is the process of forcing a computer component
to run at a higher clock rate.

50. What is memory bank?
Sets of physical memory modules is referred to as memory
banks. A memory bank serves as a repository for data, allowing
data to be easily entered and retrieved.
51. What we need to consider before connecting a memory to
the system?
a. Capacity of the RAM required
b. Check if installed memory is supported by motherboard and
processor
c. Form factor of the RAM
d. Type of RAM needed
e. Warranty of the RAM
52. What is Upgrading the memory?
Adding a memory module to the existing bank on the available
slot or replacing the previous one with the increased memory
size is also called upgrading memory. This will surely increase
the performance of the computer.
53. What is BIOS beep code? What it does mean?
BIOS beep codes are the signs of different issues of the
computer. The beep code may vary depends on the

manufacture of BIOS. For example in case of Award BIOS the
beep code will be,
1 long beep- shows memory problem
1 long beep and 2 short beeps- failure of DRAM parity
1 log beep and 3 short beeps- signifies Video error
Continuous beep- signifies failure in memory or Video
memory.
54. What are Solid State Drive means?
A solid-state drive (SSD), sometimes called a solid-state disk
or electronic disk, is a data storage device that uses solid-state
memory to store data. SSDs use microchips which retain data
in non-volatile memory chips and contain no moving parts.
Compared to electromechanical HDDs, SSDs are typically less
susceptible to physical shock, are silent, have lower access time
and latency, but are more expensive per gigabyte (GB).
55. What is RDRAM?
Short for RAMBUS DRAM, a type of memory (DRAM.
developed by Rambus, Inc.
56. What is SIMM? Is it is using now?
Acronym for Single In line Memory Module, a small circuit
board that can hold a group of memory chips. Typically,
SIMMs hold up to eight (on Macintoshes. or nine (on PCs.
RAM chips. On PCs, the ninth chip is often used for parity
error checking. Unlike memory chips, SIMMs are measured in
bytes rather than bits.
Now a days this memory module is not used.
57. Why do we call motherboard a motherboard?
Motherboard is the basic integrated board of the computer on
which all other components are connected. So that usually we
call motherboard a “motherboard”.
58. What is motherboard? What are the different types of it?
Motherboard is the basic integrated board of the computer on
which all other components are connected. This is classified

mainly into three Desktop, Laptop and Server motherboard.
59. What is the difference between integrated and
non-integrated motherboard?
In integrated motherboard all of the external ports will be
present. But in case of non-integrated motherboard only some
important ports will be available instead of all. The
non-integrated motherboard is an old type of motherboard
which now a day’s not commonly available.
60. How a server motherboard different from a desktop?
A server motherboard is different from a desktop in features
and performance. The number of processor support, RAM
slots ,Expansion card slots etc…are more. For example the
Intel® Server Board S5000PSL has the performance and
features for growing businesses demand. It provides excellent
data protection, and advanced data management. It support
64-bit Multi-Core Intel® Xeon® processor. Eight fully
buffered 533/667 MHz DIMMs. Up to six SATA 3Gb/s ports.
61. What is form factor of motherboard?
The form factor of a motherboard determines the
specifications for its general shape and size. It also specifies
what type of case and power supply will be supported, the
placement of mounting holes, and the physical layout and
organization of the board. Form factor is especially important
if you build your own computer systems and need to ensure
that you purchase the correct case and components.
62. What is ATX? How it is different from AT? Which is using
now?
AT is a short for advanced technology, the AT is an IBM PC
model introduced in 1984. It includes an Intel 80286
microprocessor, a 1.2MB floppy drive, and an 84-key AT
keyboard. The ATX form factor specified changes to the
motherboard, along with the case and power supply. Some of
the design specification improvements of the ATX form factor
included a single 20-pin connector for the power supply, a

power supply to blow air into the case instead of out for better
air flow, less overlap between the motherboard and drive bays,
and integrated I/O Port connectors soldered directly onto the
motherboard. The ATX form factor was an overall better
design for upgrading.
63. What is the need of expansion slot in motherboard?
Alternatively referred to as an expansion port, an expansion
slot is a slot located inside a computer on the motherboard or
riser board that allows additional boards to be connected to it.
64. What is PCI slot? How is different from PCI Express
(PCI-E)?
Short for PERIPHERAL COMPONENT INTERCONNECT, a
local bus standard developed by Intel Corporation. PCI
Express (Peripheral Component Interconnect Express),
officially abbreviated as PCIe, is a computer expansion card
standard designed to replace the older PCI, PCI-X, and AGP
bus standards.
65. What is AGP slot? What is its use?
The Accelerated Graphics Port (often shortened to AGP. is a
high-speed point-to-point channel for attaching a video card to
a computer’s motherboard, primarily to assist in the
acceleration of 3D computer graphics. Since 2004 AGP has
been progressively phased out in favor of PCI Express (PCIe).
66. What is jumper? What is the need?
A metal bridge that closes an electrical circuit. Typically, a
jumper consists of a plastic plug that fits over a pair of
protruding pins. Jumpers are sometimes used to configure
expansion boards. By placing a jumper plug over a different set
of pins, you can change a board’s parameters.
67. What CMOS and CMOS battery?
Short for complementary metal oxide semiconductor.

91. How can you format a floppy? What is happening if you do
so?
Insert the floppy to the system and open my computer. There
we can find the icon. Just right click and select format option.

Otherwise we can use format command . Formatting a floppy
will creates sectors and tracks on the floppy.
92. System is not showing floppy disk drive icon in

The device is not detected or disabled.
93. I have inserted a new floppy disk into my drive. The data
can be read. But not able to make modifications. Why?
The disk may be in write protected mode.
94. What is HDD? What are the different types available in the
market now?
A hard disk drive (HDD; also hard drive or hard disk. is a
non-volatile, random access digital magnetic data storage
device. It is the secondary storage media. There are different
types of hard disk, based on the the intefaces they used we can
classify them as IDE, SATA, SCSI etc…
95. What is SATA?
Serial ATA (SATA or Serial Advanced Technology Attachment.
is a computer bus interface for connecting host bus adapters to
mass storage devices such as hard disk drives and optical
drives. Serial ATA was designed to replace the older parallel
ATA (PATA. standard (often called by the old name IDE),
offering several advantages over the older interface: reduced
cable size and cost (7 conductors instead of 40), native hot
swapping, faster data transfer through higher signalling rates,
and more efficient transfer through an (optional. I/O queuing
protocol.
96. In Speed how SATA is different from IDE?
SATA- Serial Advanced Technology Attachment (SATA. is high
speed serial interface designed to replace IDE and EIDE drive
standard SATA has a seven pin connector. SATA transfer
speed of data up to 600 MB per second. Now a day use SATA.
IDE- Integrated Drive Electronics (IDE. it has a 40/80 pins

connector. IDE transfer speed of data up to 100/133 MB per
second few time ago mostly use IDE.
97. What is eSATA?
External Serial Advanced Technology Attachment or eSATA is
an external interface for SATA technologies. eSATA cables are
narrow and can be up to 6.56 feet (2 meters. in length. eSATA
requires its own power connector. It is still an excellent choice
for external disk storage.
98. What is SCSI? Is the SCSI Hard Disk is needed for a home
purpose?
SCSI is Small Computer System Interface , is a type of
interface used for computer components such as hard drives,
optical drives, scanners and tape drives. SCSI is a faster, more
robust technology than IDE amd SATA, and has traditionally
been utilized in servers. Aside from speed, another great
advantage over IDE and SATA is that the SCSI card can
connect 15 or more devices in a daisy chain. The controller
assigns each device its own SCSI ID, allowing for great
flexibility towards expanding any system. It is more costly. It is
not needed for a home purpose.
99. Is there is USB HDD? If yes what is the speed?
Yes. If your HDD is based on USB 3.0 it can offer a maximum
transmission speed of up to 5 Gbit/s (640 MB/s), which is over
10 times faster than USB 2.0 (480 Mbit/s, or 60 MB/s).
100. What is IEEE 1394 Interface?
The IEEE 1394 interface is a serial bus interface standard for
high-speed communications. The interface is also known by
the brand names of FireWire (Apple), i.LINK (Sony), and Lynx
(Texas Instruments). IEEE 1394 replaced parallel SCSI in
many applications, because of lower implementation costs and
a simplified, more adaptable cabling system. The original
release of IEEE 1394-1995 specified what is now known as
FireWire 400. It can transfer data between devices at 100,
200, or 400 Mbit/s.
