When ever i start my computer i get a short beep and then a blank screen(nothing appears on the screen) this problem gets solved when i restart my computer.
I have unplugged and replugged all cables,ram,graphics card,hard disk cables etc.
No power problem at all
My configuration
Intel db75en
Zion ram 4gb 1333Mhz
core i5 3330 @ 3.0Ghz
cooler master 500w PSU
Ati 6670 hd gddr5 1gb and cooler master cabinet.
P.S i am 100% sure that this is not a problem of my graphics card.
I will be obliged to get help
