The optical mouse gets power at port. Nothing wrong with mouse. I did a bios flash to 3C and port went dead and broken raid strip. Flashed back to YP bios fixed broken raid strip.Using usb port now for mouse. Any idea's on how to fix this? I can only figure it's a hardware problem with motherboard?PS/2 mouse port dead! I can use computer without ps/2 mouse working so I do not want to send mother board back right now, I have a 1.5yrs left on war of motherboard.
