ASUS P5Q Pro LGA 775 Intel P45 ATX Intel Motherboard

Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor Model BX80570E8400

System is freshly built and the system boots up, drives spin, fan spins and the fan on the card spins (I plugged a pcie cable into it)
I get no display on booting up, the monitors (I have two), stay in "standby" mode.
No POST beeps
Resetting the RTC Jumper allowed the display to work for *awhile*, and then it stopped working again.
What I've tried:
- Swapped Video Cards
- Reset CPU
- Tried different pci-e port
- removed ram, swapped out old ram
- cleared cmos
- removed mobo screw near pci-e port
I am out of ideas as to what to try next. Since the system boots up, it doesn't seem to be a RAM issue. Anyone have other ideas as to what I can try to get the display working?
