Windows is probably switching to a video mode that is not supported by your monitor.  Can you get into Safe Mode?

no cant really do ne thing but get into my set up from the first boot up screen...after that it jus kinda does its own thing and yea cant really do ne thing...i took my pc from my house where it was runnin fine then i took the pc to my friends house and it started this BS....its been running great till it got here...

Your kidding right?  You have the answer.  You need to hit F8 at boot, go into VGA mode and re-adjust your resolution back to 800 x 600... then reboot and it should be fine.

no it was f5 and i had to rebot in safe mode and then do a system restore...dont know why cause i didnt change ne thing between the day it messed up and the day i restored to but oh well...its all good now.....
