Slow downs in streetfighter 4 after playing hooked up to widescreen

Hello, im new to these forums and this is my first post but anywase here is my problem.
Recently i had hooked up my m11x r1 to my widescreen and played street fighter 4. The game ran perfectly fine, and the labtop was connected to the tv for about 3 hours. Afterwards, i unhooked it, and brought it back to my room, and a little while later turned it back on and played sf4 once again, but this time i was getting some rather nasty slowdowns. I went into to training mode (for those who dont know you fight against a dummy) to try to figure out if certain moves with alot of affects caused, but alas, it seems it would slowdown even when doing the simplest moves such as punching or just kicking at times. I ran the benchmark without v-sinc on and my max was about 111 fps, and the lowest without the slowdowns was about 50, but when the slowdowns hit it would dramatically go down to 30-11 fps, particularly when the match or round ended, has any1 else had this problem with other games or just with sf4?, and is there anyway to fix it, im about to try some other games and see how they far and will post back as soon as possible.

 

are you GPU overclocked? good be a driver crash. try to restart it should fix it. if it happens again take off or tune down GPU OC if you are OCing.
