This is what happened. First off I'm running Windows 7 64bit. I downloaded a password protected RAR archive and then downloaded a password cracking program to get the password. I scanned both files and they were clean. About 30 seconds into trying to crack the password my computer rebooted. It then proceeds to start windows normally or to restore settings. I try both and either the computer will just sit there and the screen shuts off or it restarts. I tried all the F8 options and nothing worked. I then tried to re-install the OS and while the cd loads files and it gets to the Starting Windows 7 screen the monitor goes blank and just sits there. I decided to give win xp, 98, vista, various linux operating systems and the same thing happens. With a modified version of Win xp for external devices I was able to get to the partition screen and wiped and partitioned the disk. I was able to do a install but received an "system32/hal.sys is corrupt or missing." Not sure what else to do... Any suggestions?
