When I try to boot up my other computer it gets to the loading Windows screen and then restarts. I disabled restart on system failure and then a blue screen comes up and says system failure. I tried to boot in Safe Mode which does the same thing, reboots the computer. I tried to boot off of my Windows XP cd, it still reboots. Does this mean that the hard drive is fried or? If I go out and buy another hard-drive would it then work?
