e5200+g31m-s2l dual core not working

Please clear your CMOS and be sure you are using the latest BIOS. Then go into the BIOS and load optimized defaults and it should be ok after that.

Only real way to test would be using another board to test with to be sure. It could just be a error though, please try the above things and see if it helps

How to clear CMOS is posted in the second post in this thread >>

You could also try uninstalling your CPU in device manager and reboot and let it reinstall the drivers, sometimes windows driver errors can mess this up as well. you could also setup a dual boot and test a clean install if you wanted to
