PC keeps turning off during O/S load

Hello,

I have a custom built PC (several years old) which does some light hosting. Recently it's been powering itself off, and now it won't even finish loading the O/S before it powers off.

I have tried different PSU, RAM, and HD and it does the same thing so I'm assuming it's MoBo/CPU related. The CPU fan appears to be working fine.

If left on without a bootable drive it doesn not turn off, so it must be related to the increased demands of trying to load the O/S.

Any suggestions to remedy this, or further narrow down the problem component?

Check capacitors on motherboard for swelling or leakage. Tops should be flat. Pay special attention to those around CPU socket (VRM caps).

It still looks very much like overheating. Have you cleaned out all the dust? Also remove the Heatsink from the CPU, clean it's and the CPU's Surface from any thermal transfer paste residue, then add a very small drop of fresh thermal transfer paste to the top of the CPU. Then firmly and properly reattach the Heatsink.

If after that you still have the same issues, replace the Powersupply. Also look for cracking, leaking or bulging capacitors on the mainboard...

Thanks for the suggestions - will try cleaning and replacing CPU with thermal paste. There are some slightly bulged caps so if the CPU clean doesn't work I guess the MOBO caps have gone.

If they (caps) haven't already, they soon will. Best to replace mobo or upgrade.

As bad caps can also cause the PSU to malfunction I'd also replace that. That really means you would have to replace half of the PC. Possibly a new one would then be a better investment...
