I replaced my motherboard, CPU & memory. Upgraded from 939 socket to AM2+. After installing drivers for the MSI board, I had no graphics after windows started. Changed graphics card, and now I can see, but the mouse won't work, the keyboard won't work. Tried booting in safe mode, no good. I think I jammed up the drivers somehow. Can someone help me back out of this without re-formatting the hard drive?
