I've got a strange problem. Yesterday morning I turned on my TV and had no video signal coming from my PC. I shut it down and powered my PC back on, and still no signal. I switched cables, still nothing. I checked the VGA connection to the PC connection on my TV, and it worked. At first I thought the HDMI controller on my TV was shot, but I hooked up another PC to it through HDMI, and it worked. Now I know the problem lies with my PC.
I have done all troubleshooting, and still can't get a video signal (other than through RGB connection). Through VGA I'm now seeing BOOTMGR MISSING, CTRL+ALT+DEL to restart. In the devices in bios I see all but one of my secondary hard drives. Even unplugging that drive, I still have the same problem. I have switched cards, and know that both cards work, as well as my LCD. I know that my cables work also. Any help would be great, I am lost now.
UPDATE: I'm now in windows on a VGA Connection. I should also mention that there is no video signal even in bios from HDMI or DVI. Going to reinstall drivers now.
UPDATE 2: I'm up and running on a DVI connection on my old 8800 GTS, but I get no signal until windows loads. No video signal from HDMI or DVI at bios.
