Lenovo Thinkcentre m55e is not displaying.

Recently, I had upgraded my Lenovo Thinkcentre m55e with a new power supply and also a new dedicated graphics card. After connecting all the pins and cables, etc, and turning it on, I connected it to my VGA display and there is no signal detected. All the fans work, and it also shows hard drive access from the lights, but nothing is showing up. The video card itself in question is a XFX Nvidia 9600 GSO 768mb version. I did not connect my monitor to the video card, but to the default VGA port on the computer. Is it possible that the motherboard automatically disabled the Onboard Video and enabled only the video card?

CPU: Core 2 Duo e6600 @ 2.33ghz
GPU: XFX Nvidia 9600 GSO 768mb
RAM: 2gb DDR2 PCS-6400

Thanks for your time and responses, King_Barrion

"Is it possible that the motherboard automatically disabled the Onboard Video and enabled only the video card?"

Not only possible but very definitely. The BIOS always disables the on-board video adapter when an alternative GPU is installed to avoid a driver & resources conflict.

When you remove the graphics card the on-board one is then enabled again.

What I don't get is why you installed the GeForce card but connected the monitor to the on-board connector - - doesn't make much sense.

The reason I did that was becuase I didn't have a DVI monitor at the time, which is what the XFX 9600 GSO 768mb card uses. However, I recently used a HP Ultra Thin Elite L2201x monitor with a DVI-To-DisplayPort cable to connect to the video card and there is still no image on the monitor.
