    Most of the problems are improper socket contact. I have worked on many and not see this  problem even once. I have resseated CPUs due to excess heat caused by fan dust or non working fan but the is is due to overheat. Overheat and hard drive failier, I believe. would rank as number one and two ?   If I did have dirty contaacts on  CPU pins, I would carefully clean them with spray tuner cleaner.

COMPUTER SHUTS OFF


There are several reasons for Auto shutdown of the PC, it can shutdown due to CPU processor overheating, Hardware conflict, SMPS voltage supply issue. what ever may be the reason, if you have knowledge of assembling then you can try below steps
1. Open the cpu cabinet and remove the heatsink then clean it.
2. clean the CPU Fan (use some spray like WD40)
3. Remove the old heat sink paste from the processor and apply heatsink paste and refix all the hardware.
4. check the voltage supply of the SMPS (power supply unit)
otherwise you can call computer hardware engineer and get the problem fixed.

Need to upgrade cpu for using multiple progams at on time, can cpu be upgraded on this older model compaq presario S0000 / 8000 series computer


As you have stated it's a Compaq Presario S0000/S8000 SERIES desktop computer.

One of the S0000/S8000 series.
Without knowing the exact model number I have no idea of what hardware is installed on the motherboard.

On the back of the computer tower, or up on the side, is a white Service Tag.
P/N = Product Number. This is the exact model number I need.

Also; Going to HP Support with the exact model number may not reveal the info I need, either.
They may not list the specifications, and therefore the installed hardware, for your computer.
There is an easy way around this, however.
Use CPU-Z from CPUID.com

What info is needed in order to know if the Processor can be upgraded:

A) Processor Socket: What processor socket is installed on the motherboard. This is what the Processor sits in.

Just two examples for Intel processors; Socket 478, and LGA 775 processor socket.

1) http://en.wikipedia.org/wiki/Socket_478

With this style of processor socket, the processor socket has the socket holes, and the processor has the contact pins. (478 holes/478 pins)

2) http://en.wikipedia.org/wiki/LGA_775

With this style of processor socket, the socket has the pins, while the processor has contact pads.

There are other styles of Intel processor sockets. There are also AMD processors which can be used, and have many different processor sockets also.


B) What motherboard chipset is used.
Specifically, what Northbridge chip is used.

3) Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

For your motherboard the motherboard chipset is a Northbridge chip, and a Southbridge chip.

{So aptly named Northbridge, and Southbridge, for the relation of how they sit on the motherboard.
Looking at a motherboard as if it were a map, the Processor sits to the North.

The Northbridge chip sits close to the Processor.
The Southbridge chip sits to the 'South' on the motherboard }

The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and High-speed graphics.

The Southbridge chip handles the slower capabilities of a computer.

4) Motherboard Diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

Knowing what processor socket is used, and what Northbridge chip, we can accurately determine what processors are supported.

CPU-Z is a tiny, free program that without opening your computer, tells you what hardware is installed on your motherboard.
Tells you what processor socket, and Northbridge chip are used, for one.

5) This is information on CPU-Z. Shows you a screenshot of the user interface of CPU-Z,

http://en.wikipedia.org/wiki/CPU-Z

Left-click on the CPU-Z user interface to the upper right of the page, to enlarge it.
(Under the bold CPU-Z heading)

When CPU-Z opens it automatically opens to the CPU tab.
(Central Processing Unit. Another term used is Microprocessor, or simply Processor for short)

To the right of - Package - tells you what processor socket is used.
Clicking on the Mainboard tab tells you what motherboard chipset is used.

6) CPU-Z download page,

http://www.cpuid.com/downloads/cpu-z/1.56-setup-en.exe

Left-click on Download now! in the purple rectangular box.
A small window will come up on the right side -
Opening cpu-z_1.56-setup-en.exe

Left-click right on Save File
Another small window will come up on the left.
In the header at the top of this small window, tells you where the file will download to.

In the wording may be Desktop, or My Documents, or Downloads.

Desktop: The file will be on your desktop screen.

My Documents: Left-click on Start, then on My Documents

Downloads: Left-click on Start, then on My Documents. DOUBLE-click on Downloads.

When you see the file name DOUBLE-click right on it.
Follow the easy installation instructions.

Go back to your desktop screen. Double-click on the CPU-Z icon.
When CPU-Z has loaded, come back here in a Comment, and tell me;

1) In the CPU tab, what is stated to the right of - Package

2) Left-click on the Mainboard tab.

What is stated to right of;
A) Manufacturer
B) Model
C) Chipset
D) Southbridge

What kind of CPU coolers are compatible with HP Pavilion a1710n?


That's a hard question to answer, you need to fine out what CPU you have inside and then look up CPU coolers for that CPU style. Since your using a pre assembled machine you may have a specialized hole pattern making an aftermarket cooler hard to find. and use.

My heat sink got dirty and caused a thermal event alarm (overheated) the computer will shut down when the cpu is taxed. do i need a new cpu


No, if the computer will start and it run bios screen and boots into windows
the cpu is fine, you need to get a better cpu cooler.

Buy a better cpu cooler for your socket, coolers are designed for the Socket that the processor plugs into.

Go to Newegg.com and llok for a cooler, you will see reviews by people
and if they liked the cooler, there are little eggs next to the product
is it has high ratings, you will see what I mean when you look at the site.


The page I posted is already on the cooler page, just llok to the left side
and look at sockets and pick your socket out to look at coolers for your system.

Cpu upgrade dell dimension 5100


Hi, according to the Dell website you have a LGA775 socket on your motherboard. Therefore, you can only buy processors that fit into this socket. Here is a list of some offered by Intel that will work: Celeron D 325 2.53 GHz Celeron D 330 2.66 GHz Celeron D 335 2.8 GHz Celeron D 340 2.93 GHz Pentium4 520 2.8 GHz Pentium4 530 3.0 GHz Pentium4 540 3.2GHz Pentium4 550 3.4 GHz Pentium4 560 3.6 GHz Pentium4 570 3.8 GHz The processors that won't work are the ones that are not compatible with this socket. Everytime you look up a cpu it will tell you which socket it is designed for. To buy a cpu you will need to decide: The brand you want. The speed of the cpu that you want. Extras i.e. Hyperthreading, etc. How much you are willing to pay for it. Then you can narrow your search as you stick within your limits. Let me know if you have more questions. Good Luck
