Last night my computer froze, so I turned it off and on. When I turned it back on a screen popped up saying "yadayadayada mainboard" pentium inside, and in the corner it says bios-delete. There was nothing different, thats whats always been there since I got the computer. After that, it goes to a black screen and nothing happens. I can hear the computer running and I know everythings on. Any ideas whats going on? It just did this out of the blue
