Black screen on Windows 7 startup

Anyone experiencing a black screen after the “starting windows screen” Win 7 64? Only happens first time of power on, is fine after force reset. I tried installing all different drivers for my sapphire 5850 toxic. I discovered if I replace it with an old x800xl all is fine. No problems. Can this be that the card is faulty or what? Can it be that the power supply is to small? I didn’t overclock anything. My specs are: Rampage 2 extreme, 6gig dominator 1600, I7 920 and 650 Coolermaster PSU.
Any help is appreciated, thanks in advance.
