I have a GF2 MX400 PCI. Well what happened was, I put the card in another that has integrated card, and forgot to tighten the screw, and its came out while the puter was on, then I powered off, and screwed it back in tight, and powered on, and when it gets to the boot up screen, when its about to go to the desktop, it freezes....is it blown? Or is it just a driver conflict?
