ATI Radeon 9550 Oversized Background Resolution

[SimTramp]

I recently installed an ATI Radeon 9550 graphics card in an old Dell Dimension 4400. It worked fine but the PC had been in storage for a few years so I installed a bunch of new Microsoft updates and now the desktop background is way oversized. When running a 1680 X 1050 desktop resolution the desktop background has hidden about 30% of a 1680 X 1050 picture (the bottom and the right side) no matter if you stretch, tile or center the picture. I opened a paint program and sized a blank template to 2098 X 1315 and placed the 1680 X 1050 picture against the top-left sides to get a picture centered properly in the desktop background. It’s certainly something I could live with but it’s not right and is likely an indication of other underlying problems. Any Ideas??
