Multiple PC freezing problems

Fledge · 2 Jul 2010 at 11:36

If my PC is idle for 20-30 mins is freezes.
Sometimes when I am using it normally for <10mins it freezes.
In some multiplayer games when I open the server list, it freezes.
Four times when I have been trying to write this thread, it has frozen. That's 4 times more than usual, lately. It's being ridiculous today. I'll just have to keep it off until I find some sort of fix today :S

When it freezes, all I can do is hit the reset button.

I've tried... reinstalling my OS: Win7 64-bit --- resetting clock speeds --- defrags and regcures as well as other things that escape me right now.

Help, please.

Windows Memory Diagnostic sometimes says I need to contact my manufacturer but sometimes says my memory is fine :S

I'm almost certain that all the power cables are in, but I'll have a look later to check.
CPU temps range from 35-60, I built this pc around easter this year and it did have some similar problems to start with but I was sure they'd been fixed. It has been working fine ever since, until this week.
Sometimes it works great for hours and I can shut down normally - but usually I start up and freezes after ~2-3mins and I try about 4 times, run memperfect and regcure, it still fails so I give up.

I hope this helps.

Thanks for the advice, I'll try all this when I can give myself a decent amount of time to do it carefully.
In the meantime, my hard drive has started making a lot of activity noise, and it takes longer to boot - ~10secs more.
