When I first started up my computer today it let me get to the desktop, After which it blue screened and I forced a shut down. When I started it back up I got a post screen that said that the overclock failed so I went to the bios and set all the setting to default. I then restarted and now when it gets to the part to sign in it is just a blank screen with my mouse curse (which I can move around)
I am running 64bit windows 7 home premium
