Computer locks up every night

It seems like almost every time I leave my computer alone for 6-7 hours, which usually happens to be overnight while I let things download, it locks up. It even locks up occasionally while I'm using it but not nearly as much.

When it locks up at night and I restart the next morning, I get repeated errors from PerrGuardian and have to reinstall it. Also, if Firefox is running, all my settings get blown away and I might need to reinstall it.

All my BIOS settings seem to be normal and it isn't overclocked(mainly because I can't get it to OC stabily at all). I've ran spyware and virus scans, so it's not that. I don't think it could be from heat. It runa hot, but not that hot (mid-40's idle and mid-50's under a full load). I've ran Prime95 for 3-4 hours during the day without problems.

I'm begenning to wonder if it's my hard drive crapping out because of the corruption afterwards. I've heard from a few people that Seagates are notorious for going bad. Mabey I'm just looking for an excuse to buy a Raptor. Who knows...

But anyway, does anyone have any ideas as to what could be causing these crashes?
 
Well last nite I was trying to set up peerguardian and limewirepro and it just restarted on me and wiped out my firefox settings.
 
Too many variables at this point :)

It could be a software issue (unlikely, though) or a hardware issue, related to the PSU, RAM, mainboard, HDD or something else.
 
I don't think it would be my PSU. It's an Enermax 465w.

I'm not exactly happy with my mobo/ram combo, so if the problem persists, I might try swapping them out.
 
Have you tried running memtest86 in addition to Prime95? If those hardware diagnostics turn up nothing, a good reformat/reinstall works wonders with software issues.
 
Prime ran for a good 6 hours before I left my computer last night with no troubles, and was still running 8 hours later when I woke up, but when I got home from school it was locked up again.

I've flashed to the latest BIOS, and I'm about to downgrade my video drivers to see if that'll help. If not, I'll just reformat this weekend and go from there. If that still doesn't help, I think I'll swap out my HDD and see what happens.

Edit: As for Memtest, I've ran it a little bit, but not much. I might go ahead and leave that running tonight to see how that goes.
 
I ran Memtest for just under 8 hours today without any problems.

Looks like I'm reformatting this weekend...
