I recently purchased a K8Neo2 Platinum while upgrading my system. The new board had some problems, such as BSODs (machine check exception), and the mouse would only work every other boot. Upon updating to BIOS version 1.09, all of these problems went away save one, my PS/2 Optical Mouse no longer is detected. Windows says there is no mouse installed at all. The mouse's laser is lit, however, and unplugging/plugging the mouse back in has no effect. I've already resetted to CMOS defaults. The system is not overclocked. Below are my specs:
