Eric,
With the other problems you listed it sounds like it is time to FDisk/Format/Install from the Cabs again.
There is one thing I would like you to check though. In your motherboard manual on page 23 it talks about power management. It looks like power management is disabled by default. You need to just enable the first one for it to work with your OS. Leave all the other options under the power management setup page disabled.
Take Care,
Richard
