As i install windows 7, bu the Part where Windows expands the folders and data, i get a bluescreen or the screen goes black or something weird happens like, the upper part of my screen is red and the other parts are blue and white pixels
Does it happen at different stages all the time?
I would test your RAM with memtest. I can remember having nothing but seemingly random problems installing windows before and it was caused by bad ram. It took me ages to find out!
