Ok, so, I've only read about a billion different posts on all the different potential problems I could be having, but I haven't found one that fits exactly what issue I'm having, so I'll post here. I just recently finished building a desktop computer and I can't get the OS to install. I am attempting to install XP Pro from a burned copy I received from the MSDN Education Alliance which has SP2 already included. I have already finished partitioning and formatting my drive, however, this is where the majority of the issues begin. A whole list of things starts happening as soon as the partitioning and formatting is finished. Either: The computer boots up, never makes it to the logo screen, freezes on the black screen and stops. Responds to nothing, needs a reboot. The computer boots up, makes it to the logo screen. The loading bar beneath the XP logo moves for a few seconds, freezes. Responds to nothing, needs a reboot. Boots, makes it past the logo screen, goes black, freezes, reboot. Boots, makes it past all of the above, proceeds to "Setup is being restarted.....", sits for about 3 minutes, locks up on "39 minutes remaining", reboot. Boots, makes it to "35 minutes remaining", locks up, needs a reboot. Boots, doesn't even make it as far as how much time is remaining and just sits on "Setup is being restarted....", which is where I'm currently stuck. The first time some of these problems were resolved by the fact that I didn't have all the power ports plugged in on my video card, but they all started up again within an hour or so. I've tried running a repair from the CD. I've tried running chkdsk /r, which locks up at 50% and needs to be rebooted. I've also unplugged all additional devices except for my keyboard. The only thing I haven't tried is removing/replacing internal parts because the case is very small and getting everything in there in the first place was a pain and I'd rather not have to take it all apart again.
