A few days ago i bought a new BFG 8800GTS 512mb and since iv fitted it iv had no end of problems. Every now & then my PC totally freezes, mouse & vista clock dont move and there is nothing i can do but pull the plug. When i do this the graphics card fan spins like crazy & the screens stays black. After a few turn on/turn offs it sometimes starts up again & then gets stuck on random parts of the start up procedure. I dont get any error message or BSODs when the PC finally does start up, just a message sayign the PC wasnt turned off properly.
Since this started when i installed my graphics card im guessing its something to do with this, but im hesitant about sending it back before i can rule out any other possible causes.
cheers guys.
