No I was unable to test the RAM, when I try to boot from the USB with memtest on it, I get a black screen with a flashing _ and it beeps rapidly until I restart at the switch.
When I go to uninstall programs I can't find anything to do with the atheros driver
I will run another Disk Check now.
I didn't do the hard drive test as I need a spare disk which I don't have at the moment, may be 2 weeks before I have the money to get any but once I have some I will do it.
Edit:I will do the Disk Check tonight as last time I done it, it took a while.
