My PC appears to boot fine, I can hear it get to Windows but I can't see anything on the screen. The screen is completely blank/black... no POST/BIOS/Windows etc. The problem only happens when my 8800 GTS is plugged into the screen (LCD). Using an alternative video-card or on-board video works completely fine.
Things I've tried:
- Different (brand new) motherboard
- Different PSU
- Many different H/W combinations (just in-case it was conflicting with something)
- Tested every stick of RAM individually
- Cleaned off the video-card's contacts (using a rubber) and all the dust on the fan
- Different DVI cable
- 2nd DVI slot on the card
Also, if I unplug the power connector from the PSU to the video-card it beeps. Plugging it back in stops the beeps.
I'm running out of ideas... is my card dead?
Edit: I have a sneaky suspicion that the primary DVI port might be the cause of the problem. Is there any way to force it to use the secondary DVI port?
