I really don't know what catagory this would go under. I have a Windows XP computer AMD Athlong 2100 CPU, Abit KX7-333R motherboard, AMD thermal colling system, 1 gb ram, 80 gb hd slave, 80 gb hd master, DVD drive and burnerATI all in wonder radion 8500DV 64MB video card. This computer will either shut itself off and on by itself or completely turn it self off. I thought the problem was because my wall electric plug in was not grounded (which I had fixed), but it still seems to enjoy doing this!! I have had the computer checked out by a tech and he couldn't find anything wrong with it. The only time it does this is when I am either working with video editing or with photos. I also have a monitor to tell me if its overheating and no problem there. Can anyone please help me with this problem! Thanks
