Building Tower, GPU is not overriding Onboard

[DrGrass1987]

I AM USING WINDOWS 7 RC1.

I am in the process of building my friends computer. I am having a problem concerning the On-Board Video and the ATi 4890.

Here's the components i am dealing with.

MSI 790GX-G65 AM3 AMD 790GX HDMI ATX AMD Motherboard

HIS H489F1GP Radeon HD 4890 1GB 256-bit

Ok. Here's what I've done. PSU Hooked up to all appropriate fittings (this GPU has 12 pin wholes for the PCIe Hook Ups). Windows has been installed one the rig, and is running. I am in the OS on my main computer, but the one i am building HAS the OS loaded, the Monitor i'm using is plugged into the GPU Video Socket and NOT the Mobo's integrated video socket. There is a picture on the monitor (resolution maxes out at 800x600 or something stupid like that). It is saying that the Display Adapter powering the monitor is definitly the onboard gpu, it's only 8MB.

That all said, everything on the system is working. The fans are all powering on, the CPU-Z is IDing the processors speed correctly, the USB ports all work, the HD is registering, the Optical Drive works. I just don't know how to enable the video card to be activated. The image on my monitor IS coming from the GPU, just not getting all the info that my 4890 should be producing.

I'm assuming i need to disable on-board video, and after looking through the manual i cannot for the life of me find the bit on disabling the on-board video. Could someone help me please?

On startup press delete repeatedly and change the setting via BIOS.

Yes, you need to go to device manager and disable the onboard Graphics from there

Very simple and should fix the problem.

Start> In the search tab type in "Device Manager" (Fastest Way IMO)

The motherboard you purchased has Hybrid Crossfire. In otherwords you will get more performance if you leave the onboard VGA enabled, it will also be more economic as when your friend is not playing games it will essentially shut down the bigger graphics card until it is needed again.

Plug the monitor into the Mobo OnBoard display connector to use Hybrid Crossfire.

Hybrid Crossfire

■Supports Onboard VGA with PCI-E graphic card combination
■Easy to install
■Double the graphic performance to meet your processing needs
■Save the money for two graphic cards and to reach ATI Crossfire function easily

Ignore my last message appears Hybrid is for lower spec cards, oops!

System Request
1. Hybrid CrossFireXTM is only supported with the Vista operating system.
2. Graphic card based on an ATI RadeonTM HD 2400 Series2, ATI RadeonTM HD 3400
Series or ATI Mobility RadeonTM HD 3400 Series graphics processor.
3. Mainboard based on an AMD 780 integrated chipset.

On the Advanced BIOS Features page there is 'Primary Graphics Adapter' this may have the option to change from onboard to PCI-e. HTH
