My PC freezes occasionally. I had to reboot the PC twice while scanning with ESET Online Scanner because the PC froze. On 3rd attempt the scanning finished successfully but the PC froze again while I was writing a letter. Sometimes I can work at the PC for hours and sometimes it will freeze like in 5 minutes or so after boot. So it does happen randomly and is not a software issue, I think, because I only have MS Windows installed. It freezes even when I don't do anything at the PC, I come back and discover it's frozen and again I have to push the reset button. It seems to be a hardware problem.
The motherboard in this PC is quite old (from the year 2000), a Chaintech 7AJA motherboard.
PS. this PC is clean from infections, I just came from here: http://www.bleepingcomputer.com/forums/topic440872.html
