I just recently upgrade my computer with a new motherboard, CPU and RAM. It was previously freezing when trying to reformat it when someone looked at it I was told that the CPU was overheating so I just upgraded. Well, when I started the computer after the upgrade it seemed to work fine. I need to reformat the hard drive so I tried but after the screen that says "press any key to boot off disk" it goes straight to a black screen. Also, it goes to the black screen right after the windows opening screen. Any ideas guys? I would really appreciate it. I have had nothing but problems with this computer ALL summer!
