Blown CPU?

[Baka^Ni]

Turned my pc on this morning and went to grab a tea, came back to find my pc turned off. Turned pc back on and it would just about make it through to the windows login prompt before turning off again.

Checked temps, all fine, memtested ram, fine.

Downclocked back to stock and I can finally boot into windows and run othos, we'll see how it goes but it looks bad .

I would have thought that a dying cpu would have given some warning before just crapping out, some error messages or corruption would have been nice.

If it passes orthos but continues to randomly die, any other ideas?

I would think that if the CPU were knackered, it would just not work, period. If it passes orthos but still randomly dies, Id do an OS reinstall, then go from there

It could be a faulty motherboard or PSU.
Try removing one graphics card and see how that goes.
Is it possible to try another PSU or check test with another CPU.

Humm, I now have MASSIVE graphics corruption, as we speak, I can see it warping and twisting the screen. I'll take a picture... the plot thickens.

That was fun, trippy lsd visuals which persisted even after a reboot.

I've tried both graphics cards independently, still dies, tried the cpu at defaults and with some extra voltage just in case, still dies.

It passes orthos, or at least it does until it powers off.

Any other ideas? Other than try another psu? I'll do that tomorrow.

Little update, if anyone was vaguely curious.

I suspect I'm suffering from an electrical short, caused by some component expanding with heat.

This would explain why the probability of the pc cutting out would approach one, the higher the clockrate went.

PC is sitting on my desk in it's seperate bits atm and it's perfectly stable, I'll thrash it for a few days and then *carefully* re-assemble it.

Gotta love these things, learn something new every day.
