today i was playing with my pc after some moments my screen gone black...
i restarted my computer and right after the Welcome screen it used to go black again
I changed the graphic card slot now it works fine but i also tried the last slot again and it doesnt even show anything for now i want to know why is that for?maybe i havent fitted to graphic card good in the old slot?
my Graphic card : Nvidia 450GTS 1GB DDR3
(i didnt do anything with my graphic card like overclocking or anything it was on the recommended settings)
