I built my first computer and, knowing nothing of powersupplies, ran a 400w supply to a GeForce 9700 OTX on a A8N32-SLI mobo with an AMD 4800+ processor. Needless to add, it burned out. I replaced it with a 680w supply, but now, on occasion I lose complete video signal. And just now, I lost video and the computer rebooted. It sound like it tried a couple times to reboot or something clicking, but what does that mean? I'm to the point where I'd rather not turn the computer on again without a fullproof solution. Newegg won't accept the video card in a return, because I don't have the box. I have everything but the box. It's stupid... Will Nvidia take it back without the box?
