My boyfriend is having the same problem. He turn on the PC (HP d530) the POST screen looks like a "vhold" screen and so does the bios screen. Boots into windows and its fine. Keep in mind this is an onboard video card. He tested with another video card and it didnt change. I read somewhere pulling the
cmos battery may resolve the issue but haven't tried this yet. Any suggestion? The system has not been over clocked
