You have? That by it's self suggests that something isn't right.

Hardware. Things like loose/dodgy RAM, overheating CPU or video card, 
loose PCI card, etc. I'd suggest just opening it up and re-seating all 
the cards, then when it's on checking what the CPU and GPU temperature 
are like by putting your hand near them (not touching them).

Also use 'smartctl' to check your disks, make sure they're reasonably 
cool, and if you're game run a disk test with the manufacturer's tools 
(after backing up). Overheating/failing HDDs can cause all sorts of 
problems, as I've had far too much experience learning.

Of course, hardware isn't the only possible cause, but if I had to take 
a guess, that'd be it.
