The memory on the video adapter has failed;  the video adapter needs to be replaced.

Thanks for the reply -- any idea as to where I can find a display adapter for sale? Costs for one of these?

I've done a limited search for anything resembling the part number, both from Dell and the numbers on the unit itself...but no luck finding anything. The Dell P/N (even the one from my Service Tag Config online) doesn't correlate to anything known on the Dell Website...

Thanks

This is the ATI card:

The higher end nVidia cards for the system run more on the order of $400-500.

I've had the same problem.  Is it very difficult to replace the display adaptor?
