I went to canirunit.com just to check how my system would stack up against Battlefield Bad Company 2. It failed. The processor according to canirunit.com was only running at 1.5GHz. So I downloaded CPU-Z and sure enough the processor is only running at 1.5GHz whereas Windows 7 reports it running at the full 3.16GHz in System Properties. So I kept CPU-Z open while I played a few games. The CPU would start off at 900MHz and when the game started up it would jump up to 1.59GHz and stay there no matter how long I played. Another thing I noticed in CPU-Z that the FSB and rated FSB of the CPU was also halved. I have an Intel Core 2 Duo E8500 and it was running fine until I thought my system was slowing down (it felt slower but I paid little attention as to why). When my PC post I can see that the CPU is running at 3.16GHz. I am thinking that my motherboard has some sort of damage. I leave the bios settings alone, always on auto. I even removed the CMOS battery overnight to clear and possible messed up settings. Any suggestions?
