I have an ASUS A7V8X motherboard and a 2000+ AMD Athlon XP processor. I've had this computer for a little over 2 years now and for some reason right not i have a big problem with it. While im using the computer at random the monitor would turn off. I thought it was the monitor's problem, however when i restart the computer it says "CPU has failed system test". When i let it sit for about 10 minutes it'll turn back on and boot into windows again and i can continue my work, sometimes however it just shuts off the screen when i enter windows. So the CPU keeps failing i think. What should i do? My motherboard keeps saying my cpu has failed system test. I've tried remounting my CPU and adding more arctic sliver to it. Didn't seem to work very well = / Please help me!
