Computer: HP dv9000t (laptop, Windows XP Pro)
So yesterday I came home and went on it, seems to be working fine like it always does. Then suddenely the screen went black for about 2 seconds, then back to normal, and five seconds later goes black again, normal again, black and so on... I decided to restart the computer. When I tried to reboot, I came to a black screen with white writing. It gave me the option of Safe Mode, Safe Mode with networking, Safe Mode with command prompt, go to last known good configuration, and start windows normally.
Both the "last good configuration and "start windows normally" options just brought me to a blue error screen that instantly just rebooted the computer back to the black screen... so quickly that I couldn't actually read what was on the blue screen.
I did a diagnostics test on the hard drive, and it came back fine. I booted in safe mode, and that seems to work fine (for safe mode that is...).
Another detail to add is that the screen now has these strange markings on it now.... like choppy lines that come down the screen in columns... they go away when safe mode boots though....
Any ideas on what the problem could possible be? Any help would be much appreciated.
