Sorry, but it is very hard to understand your problem.
What I understood from this and your other thread (why two?
) is that after some minutes the display switches off and you sometimes get a blue screen.
If this is right, please post your windows version and the output of the bluescreen.
Since these are typical symptoms of overheating please post your system temperatures (CPU, HDD) too.
Another reason could be a defective RAM. Please run
memtest86+
