My friend's Gateway M460 won't start. BIOS will start, then I get the black screen giving the options "start Windows normally, "start in safe mode," etc. When you choose any of these options, the computer gets to the Win XP screen, then the Blue screen of death very briefly, then it starts over and will continue to do this indefinitely until you shut it down. I went into BIOS to check it out and at one point there didn't appear to be a HDD, but when I checked it again, there was. I put the XP disk in to see if the comp would boot from it and it would. Is there something I should try before I just wipe the drive and start over??
