I just bought a PNY Geforce 6600GT cause my old radeon 9600xt was dieing on me and when I tried to install it the fan spins and the rest of the pc starts but the monitor stays on standby and just gives me a blackscreen. I tried calling customer support but they are closed at the moment. I am running on a 350 watt psu which is the minimum but I don't have many things hooked up to it, only 1 hardrive 1 cdrom drive, a floppy, and 3 80mm fans. And yes I did plug in the Y connector. So anyone have any idea what it could be?
