2.7 amd64 Desktop issues ( mouse, RAM, perfomance etc. )

Other things I'd do before throwing away the mainboard include:
- Read THROUGH the mainboard's manual and make sure if it really supports
  4Gbytes of main memory
- Also check to see if you need to change the BIOS configuration,
  such as `Memory Remap feature.'
  also cf. http://forum.novatech.co.uk/showthread.php?t=15073
- Make sure that the BIOS is up-to-date

Cheers.
