Originally it wouldn't pass the ASUS screen without unplugging it first. Then I changed the battery on the motherboard, and it couldn't detect any of my SATA drives (there are three). So it says the 'insert bootable disk and retry' prompt. If I unplug the computer, it will boot into Windows 7, but once it's there the usb support is very poor. Maybe only one or two low powered devices will work.
Another thing I did was give it a good dusting, and there was a lot of dust inside the machine.
