When I start my PC, it turns on, even when it worked fine it would not post and just skip to bios, and then boot, but now it doesn't show anything on the screen. occasionally, spamming the f1-f8 keys will sometimes get it into the American Megatrends screen, then booting up fine. So the system works, just cycles through a few boot attempts before showing up on the screen. While booting, the hard drive is audible, so I am sure that it does boot but just doesn't show an image.
