Ok it's time for some more hardware headache.

This time I decided to uppgrade my graphics card a GeForce 6800GT. I got a really good deal on a GeForce Gainward 7900GTX and wnet home with a smile on my face.
Not smiling now. Short story is, every time I boot up the computer completley hangs/freezes as it's about to get into windows. Hard shutdown is only way out. I can't get into windows in safe mode, same thing happens. I have checked all power connecters to the card, tried every configuration I can think of. I have a 500w Cooltek Psu, which should be enough. But no go. During Post the card is detected, memory on card seems ok and monitor shows everything alright, but then just as the windows welcome screen should appear it hangs. I tried the card in a friends machine. It worked there... So I thought I need a clean windows install. Tried that, but behold, everything is fine untill the screens shows where you choose if you want to insatall or repair windows, the computer freezes again. Hard shutdown...
Right now I'm stuck and out of ideas. Anyone got some to spare? :hmm:
Cheers Porphy
