Motherboard/CPU

By TheKandiman ·
I have a client with an IBM NetVista PC. I am not sure yet of the hardware details, but the symptoms are as follows:
Once the pc is turned on, during boot (running W2k Pro) it will power itself down after approx. 30 seconds, or once the OS loader screen has appeared. I have tested the power supply in another pc, no problems. I have also attempted to re-install the OS which worked fine until attempting to run for the first time, then symptoms returned. When checking the hardware I noticed that the heatsink had become detached from the cpu, so I cleaned the old silicon from both the heatsink and cpu, then re-applied a new layer. I have replaced the fan as well.
The problem still exists. My question is whether I should first try for the motherboard or the chip. Any and all suggestions welcome.

The motherboard seems to working since it getting power and booting the system up,the problem seems to exist with the CPU and whether or not it overheated and how long had the problem existed before client contacte you,try cpu in another system to recreate the existing problem,if so then you will know that you have an over heated cpu

take the case lid off so you can see the workings inside when you test it. I once had a similar problem and with the case open i could see the fan initially running then subsequently stopping. And don't overlook the basics - it may be such a simple thing as a faulty power cable from the power supply to the fan. If you have an unused one hanging off the power supply, try that one.

CPU = Celeron 1.00Ghz
Ram = 256Mb PC133 SDRAM
Unsure of motherboard make/model - no etchings
HD = 40Gb Western Digital 7200rpm 9.2s
Very user un-friendly bios
Graphics, sound and LAN are all on-board

You need to run a diagnostic program from dos. I use The Troubleshooter from Smart Certify. There are a lot of them out there.

They test the motherboard, cpu, memory, harddrive. All from dos.

They have a burn in routine. This runs all of theselected test over and over and over. You set the preferences to stop on error.

This will eliminate the hardware.

Good Luck Lee

Your CPU might have overheated! if its possible, try another CPU of the same speed. also, see if all the pins are still perfectly in line on the CPU and that there are non visably missing
or
try going into the bios, and loading setup defaults, or fail-safe defaults or try and re-set the bios up yourself.
