For some reason my PC freezes up when I use it, it usually happens 20-30 minutes after I log in, it happens when I have a window open, and after I try closing the window everything else is unresponsive, crtl+alt+del does nothing. I've done three different virus scans with no results.
My PC is an HP Pavilion slimline with AMD Athlon 64 X2 dualcore processor running Vista Home Premium.
Any help/suggestions would be greatly appreciated.
