Reseting PC

[jozef000]

Hello, I have disassembled 1 computer (its an old one 800mhz, 7xx RAM...)
After i assembled it back, there i have one problem.
PC restarts after 5 mins or 2 mins of starting windows.
I checked temperatures in AIDA, processor temperatures are very different, in 1 time its 2°C , after 3 seconds its 90°C and after next 3 seconds 25°C.
Can someone help me what to do with this computer pls ?

Thx a lot.

You have not seated the CPU HSF properly.
A suggestion would be to remove the CPU and it's HSF again, clean it all properly and reapply TIM on the Processor. Reassemble the CPU-HSF and make sure it is firmly fit.
Try booting the rig again and see if the temps fluctuate.

Thanks for answer, but i didnt disassembled CPU HSF. Just the motherboard and CPU Cooler and cleaned it. Is it possible that HSF spontaneously allowed ? ( sorry for bad english hope u understood )

As long as you connected the CPU HSF correctly to the Mobo CPU_FAN header, you shouldn't be in doubt. Since you did remove the CPU Cooler, an air bubble of a relatively bigger size could cause the lower contact between the HS and the CPU surface. As suggested before remove the CPU HSF assembly, clean it up well , apply new TIM and reseat it correctly with the fan plugged in.
Then give us a reading.
The cables of the HDD Led, PW Switch,RS Button, PW Led, don't matter.
