Up until today I have been using the BIOS with no problems. Only really to have a look at the new interface and changing the boot order. I have not tried to overclock. Today when I entered the BIOS my mouse was moving erratically and I could not move it accurately to choose any options. Thinking it may be my USB wireless mouse I then tried a ps/2 mouse and had the same issue. I am on BIOS version 1053. I have been using this version for about 2 weeks. The mouse is working perfectly in Windows. Anybody any ideas?
