I bought an ASUS m5a78l-usb3 off of eBay about 2 months ago, and it really has me confused, I've tried 2 different CPUs in it and 3 different OS's all it does is show a small command prompt in the top left corner, I know a couple of people have already asked this question on here but nothing they've said has worked. is there some way around this?

OK, but one other thing, I tried booting up windows vista and it managed to reinstall itself fine, as soon as I tried to load it up normally it reset itself, is this fixable?
