Accidentally pressed the CLR CMOS button while PC was on

[Wolfyplox]

So as the title suggests, I accidentally pressed the CLR CMOS button while PC was on and now my PC is stuck on this screen: http://imgur.com/pdyPqZq

None of the buttons are working on my keyboard, though my keyboard is clearly on.

Can anyone help?

So what happens when you press F1?
