My sons computer will not boot Vista 32-bit. I get the black screen and blinking cursor. It will not start in safe mode. It appears to show up in the BIOS. I inserted a recovery disk, but when I click on repair, no OS shows in the box. I clicked install (and stopped there) used the SHFT F10 option and pulled up the Command Promt. From there did the earliest system restore I could find. Restore was successful, rebooted....and still the black screen. I've tried so many things, that I don't even know where to begin. Please help! Thank you. I know a little about computers, but I am not a guru, so please try to ABC as much as possible.
