dont know if my graphics card is broken or not!?

Question

i have a geforce 8800 gtx with windows vista, i installed the drivers and it works fine for awhile then the comp turns off. But i was always able to turn it back on and reinstall the drivers and it worked again.. i had to do this pretty regularly as my comp always turned off.... today the comp turned off, and when i tried reinstalling the drivers it didn't work! when i initially turn my comp on the boot screen is black with little white blotches.. but it still boots into windows with no problems.. however the desktop stays on windows vista basic and no aero and the driver refuses to work now!... i have an intel core 2 duo e6300.. is there anything i can do to get my comp running normal again without the problems?

Answer 1

Does your power supply have enough juice on the +12V rail? Your graphics card is a 132 watter at full load.

Answer 2

i think it doesnt like vista. get a compatible card.
