My machine randomly freezes when im doing work or letting the system idle. The only way I can recover is to restart. I originally had x86_64 on my system but installed i386 to see if it still happened...and it does. My best guess to the problem is something hardware related [i have an old PCI graphics card]. But I have read that this problem occurs to some other people and disappears after a few minutes which is not the case on my system. -Andrew
