there can be several reasons to it. try to pin point the activity just before it freezes.
a very wild check if the problem is not software related  would be to make sure the cpu is not getting excessivley heated up due to fan failure.

Even though you've done a virus scan doesn't rule out that it could still possibly be a virus.  It could also be a hardware/heat issue or just a good ole windows application probably.  If possible to re-image the machine I would start with that.  If that doesn't help then you can bet its hardware related or vent issue.

Probably pushing it too hard. Unfortunately unless you want to disect every single process and service your computer is running in the background a reformat of windows is probably the way to go, start from a clean state. you could also try cracking open the case and checking your cpu fan for a heap of dust, this can sometimes cause CPU spikes.

If there is a lot of dust to remove, a can of compressed air will do the trick, which you can pick up from most computer stores, or funnily enough a vacuum will do a pretty good job too. As always be careful whenever you open up a computer.

Can you provide the mobo model and maker
snowalpsCommented:
yes very much; as i pointed earlier, now my doubt becomes stronger that it could be a heat issue since you have said you dont touch it for  4 hours and it crashes. check up your fan and the temperature of the cpu from bios .

That's an Asus, try memtest to make sure there is nothing in memory
BarsMonsterCommented:
Steps are:
1) Run Orthos thing. Both "stress CPU" and "stress RAM" modes. This should cause crash earlier.
2) Check PSU voltages while Orthos is running. Probably it is dying.
3) Check CPU temperature under Orthos load (RealTemp can show it if it is Core2Duo processor).
4) Try to put 0.05-0.1v extra voltage to processor and see if it is more relable.
5) Try to reduce FSP frequency by 20-50Mhz, increase memory timings in BIOS.
6) Try FurMark for videocard testing. Settings are MSAA=0x, 1280x1024
