Hi - since you tried the obvious things, have you also checked the temperature? It could be overheating. One way to find out is to run the comp without it casing. If it runs fine, then it takes dusting and cleaning out the vents. - Amos
Here are my specs
AMD athlon xp 3000
AK79D 400-Max motherboard
512 MB ddr400 ram
So this just started randomly, I can't think of anything to cause it to happen. At random times my computer will just go to a black screen and not respond, at which point I must push restart button and reboot computer. It can happen within 3 minutes or 3 hours. I have tried virus scans, chekced ram connection. All is fine. I ran the windows memory test and everything passed. Anyone know what can cause this? It is very annoying as I can basically not use my computer. Oh yea one more thing, I tried reformatting and installed windows on the other hard drive. It worked fine for a few weeks but then started again. Also could a corrupt windows installation cause this? I mean could a few system files that are corrupt cause a complete crash like this?
