What should be the simplest of tasks is sending me crazy.
I have a PC based on an ECS P4M900T-M2 motherboard. I've been using it for about a year using the on-board GPU. But now I want to add a second monitor so I bought a PNY 8400GS PCIe card to go into the PCIe slot on the m/board.
Should be easy, no?
But when I add the extra graphics card I just get a black screen. The PC does not even get as far the BIOS POST. If I take the graphics card out the PC boots ok.
The only relevant setting in the BIOS I can find sets the "init display first" to either PCI (eh?) or PCI Express Card. I've tried both of those but that setting makes no difference.
How the hootin' heck do I add a second monitor / video card to a P4M900T-M2 motherboard???
no... while using the onboard video card, disable the card in device manager... the your screen should black... then shut down your computer... start it back up with the 9400gt in it...
P.S. Make sure your computer is set up so if you just push the power button on the case, it will shut down.
I got the answer direct from the motherboard manufacturer....

Sadly you simply cannot run the 8400GS graphics card with the P4M900T motherboard.
