|If you are using a PS2 plug mouse, try another one. If you are using a USB mouse, make sure that it is plugged directly into one of the rear USB plugs DIRECTLY ON THE MOTHERBOARD. ALL other USB ports will NOT work at this stage. Front USB ports, USB ports on an expansion card, USB ports on your keyboard or monitor, and USB hubs will not work at this stage, and really should not be used for mouse and keyboard. If you are using a wireless USB mouse, borrow a hardwired mouse until you have windows installed and the wireless drivers installed. If USB does not work for you, borrow (or buy) a PS2 mouse or get a USB/PS2 adapter.|
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
