Blank Screen After Reboot

[Pager57]

XP started coming up with a blank (Blackout) screen after reboot installing any program. Even when I just restart the system I get a blank screen. I reformated C: 2 times it works fine then after loading a few programs it starts back up. Also tried installing different programs and I still have the problem.

Please help! I get no error warnings!

I had that problem before..MS recommends loading from the xp cd, going into the recovery console and doing a fixmbr and then a fixboot and see if that helps.
