My PC hasn't frozen a single time since the day I have Win 2000 and then XP, I've always left it running for weeks at a time without a single problem, and all of a sudden it's hanging multiple times per day (the mouse also freezes), there's normally no reason for the creahs when I reboot, but once it mentioned an ATI program. How can I find the cause of this? I'll try to reseat all cards and wires also in case that's the problem, but the PC freezes more often when I'm away and the screen turns off (after 5 minutes), if it was a loose connection is would probably freeze when I touched something, and probably not when I'm not even here.

I have many TV programs scheduled for recording so I'd like to have this corrected ASAP to not miss any recordings.

Thanks
