First post here. So, hello. =) Hope you guys can help me out. I bought an XFX 6600GT the other day. 256mb PCI-E x16 DDR3 I put it in, loaded my boot to PCI-E. Everything seems okay. I install the drivers that came with the disk, and restart. I think "Okay, ill see how it runs". So I open WoW. Within 5 minutes of opening the game, it crashes and my computer locks up. I restart, and I see some strange characters at boot. alot of these: á Load up windows, and the colors seem strange. I downloaded the latest drivers and see what happens with WoW again. Crash, and same strange characters/artifacts on boot. This time though, when windows finishes loading, my screen goes black and gives me "No Signal". And thats that. I cant seem to get it to load windows without myself getting a No Signal error. The computer seems to keep loading, but the card's fan turns off and theres no video. Any help on this would be greatly appreciated. My computer specs: ASUS m2npv-vm motherboard 400W PSU 1gig ddr2 667 RAM Sempron 3000+ 1.8GHZ and of course XFX 6600GT 256mb DDR3 PCIEx16 And yes, I have tried: Underclocking the card Checking temperature of the card (When the fan is on, it doesnt seem to go any higher than 55 degrees) Thanks guys.
