Last night, I was running my Duron 800 on an Abit KT7 (not overclocked) and all of the sudden it went into permanent sleep mode. I was playing CS at the time. I cannot diagnose the problem, but I have reason to believe the motherboard is shot. Each time I boot up the computer, there is NO beep. None whatsoever. I removed all the PCI/AGP cards and booted up. No beep. I tried reseating the memory. No beep. At last I took off the chip and booted. No beep. Does this mean the motherboard is dead? Or, if this is all just my imagination, how can I fix this if my computer doesn't even boot up?
