Recently formatted hard drive and installed Windows 7 with the driver CD HP provided with my laptop. Anytime I play a game, it runs smoothly for about 3 seconds and then stutters for 1-2. My FPS is fine for all of these games, but the stuttering is constant. I have tried reinstalling the drivers with identical ones, newer versions, older versions, third party drivers and disabling driver verification on Windows startup and I am still receiving this stuttering problem. This never happened before the reformat. I have run out of solutions to try. I dont know what else it could be. My computer is an HP laptop with a 2670QM i7, 6GB RAM, and an AMD HD 6770M gpu. Thanks in advance.
