I have had so many problems I'm not sure where to start. I had been running Vista 32-bit on my Gateway 5632e. Had Hard drive failure so I upgraded to 7 64-bit, upgraded to 8GB RAM, new hard drive and finally got it all working. Everything seemed to be fine until COD: Black Ops wasn't running very well so I thought I'd figure out what was wrong. Now my PC won't boot up with my ATI Radeon HD5770 but will with the motherboard GPU. Is this a bad video card already?
