About two days ago my computer started randomly rebooting. Since then it has gotten worse. Some times it doesnt even load windows before it reboots itself. I figured it was just my computer overheating so I did some internal cleaning. I found that my Video card fan wasnt working. I assumed that was the problem and bought a new videocard. Since then I have installed the new Video card (ATI all-in-wonderX800xt) and am still getting the same problem. My friend suggested it might be faulty RAM or too much for my power suppy to handle. I am using an AMD 1.333 processor. Its been about 2-3 yrs now since I have gotten my computer. If anyone knows why my computer keeps rebooting plz help >.< .
