I got some serious issue. I was playing a game on my laptop (warhammer 40k) and all of the sudden I got blue screen, and system restarted itsef and booted into.....pitch black screen.

After that I unpluged the laptop from power source and took out the battery. Pressed and Hold power button for 1 minute, restarted the system. Booted into Safe Mode, made back-ups onto DVDs.

Reinstalled XP pro.

Still the same problem, but got even worser. Here is an example of what I am talking about.
