Hello, Merry christmas. I have an AMD Athlon 64 X2 dual core 6400+, 8 gigs of ram, and an ATI Radeon HD 5770, with a corsair 750w power supply. My computer keeps freezing any time I attempt to play any sort of video game on it, although I can surf the web for hours and leave the computer on indefinitely and everything remains normal, just when I play games it freezes within 10 minutes. I've been told it's most likely my CPU overheating and I've done everything I can to fix that yet it still freezes. I am thinking of getting a new CPU but would like to make sure that's the actual problem in the first place before I do. Can someone please help me figure out if that's the actual problem? How would I know for sure? Also, what would be a suitable replacement for the CPU, one that will provide a nice amount of computing power but that won't overheat and give me the problems I am having now. Any help would be greatly appreciated and thanks in advance. Once again merry christmas happy holidays.
