Hello,
I have faced a real big problem with my computer.When I turn on the cpu the machine startsup normal.But after desktop screen the problem appears randomly.Problem is after 10 seconds monitor display is gone.Whole monitor turns into a blue,light green colors and nothing display.This problem occuers even when I do not touch the key board and mouse.Every time monitor screen goes to blue.A friend told me that my motherboard (INTEL D 945GCNL)does not support my GEFORCE XFX 9400GT 1GB DDR2 graphic card.Please help me.
