Graphic set up became unstable after format Dual HD Radeon 4870

Hello,

I have an Alienware M17X R2 which runs on two HD Radeon 4870 mounted in crossfire. After format, the latest drivers recommended by Dell (there are some new ones but never got them to work) were reinstalled without problem. If everything seemed to work fine, unfortunately after a little while the display starts to flicker going from blue to orange over and over, sometimes black and white.

The device manager or Catalyst software do not detect any problem.

The computer remains responsive and after restart everything is back to normal for a little time.

Sorry if I did not provide the info needed, please let me know if you need me to run any particular diagnostic.

My main concern at this point is to determine if this is a hardware or software problem.

Thanks for your time and help,

I don't know if I can help you but those that can will need to know
EXACTLY what power supply you have.

Off the top of my head a power supply of quality with a least 650W, and 4 PCI-e connectors.

The two way I know of to find out what power supply is.
1. Look at the paper work that came with the computer.
2. Opening the computer and looking at the tag on the side of the power supply.

I seriously doubt a store bought that came with one video card has a power supply designed for Two video cards.

Alienware m17x isn't a desktop nor a small form factor. It is a gaming laptop :X

You are absolutly correct RoasterMen. A laptop. My dumb ass just looked.

Okay flows69 just exactly what are the specs of the computer you want two video cards installed.
