This happens at irregular intervals, on the order of days rather than hours or weeks. It is a total freeze; everything on the screen becomes completely static, no response from the mouse or keyboard, Ctrl-Alt-Backspace does nothing, etc. Earlier, the freezes would only be partial (mouse pointer stuck, but OS accepts input from keyboard) but would happen every few hours. I tried altering IRQs in my BIOS, and now the freezing only happens every few days, rather than every few minutes or hours, but now when it freezes, it seems to be totally frozen (i.e. ctrl+alt+backspace does nothing). Copying files from a different OS on the same HD often causes a freeze, as does copying files over my wireless network. When a background fsck is taking place (after a previous freeze and hard reset, for example), the PC will often freeze again. I notice all these things involve heavy HD access. Am I right in suspecting IRQ issues as the likely culprit? What steps shoud I take to resolve this? I am using a custom built PC with a radeon 9250 graphics card and 3D acceleration enabled. Occasionally when running a 3D program, I get the following: taxa% bzflag Mesa: CPU vendor: AuthenticAMD Mesa: CPU name: AMD Sempron(tm) Processor 3100+ Mesa: MMX cpu detected. Mesa: 3DNow! cpu detected. Mesa: SSE cpu detected. r200WaitIrq: drmRadeonIrqWait: -35 and the program crashes after a couple of seconds. This will happen every time for all 3D programs. After a reboot, either the same thing will happen again, or all 3D programs will work fine. Could this be related to my freeze problem?
