Ok, for some reason my 6600GT won't output anything, through VGA, S-Video or DVI. The card is definitly part of the problem, as I'm using the same PC with a very old Nvidia TNT and everythings fine. Anyway, here's a bit of background to my story if it helps: Turned on my PC this morning, and it would stay on for about 2 seconds, then the PSU shut itself off. It wouldn't stay on any longer. I get a new 450 Watt PSU (the old one was a 400W but they're the exact same make). Now my monitor won't show anything so I have to change GFX cards. And yes I did plug in the molex connector! So what could it be? Did my old PSU screw over my GFX card? Could somehow, the current on my new PSU be worse than my old one? I don't have the ratings of the old one but the new one has: +5v = 35 A +12V = 16 A +3.3 = 28 A Anyone got any ideas at all?
