I had a spare hard drive handy, so I thought I'd clean install Vista and see how it went. Same system, different hard drive, but for some reason I can't get the graphics running properly.

I installed Vista without a problem. I installed all the necessary drivers, including the most recent Nvidia driver for my GeForce 9800 GT video card. Yet by default Aero was disabled, and things seemed a bit choppy and strange.

The Windows Experience Index rated the Processor, RAM and Primary Hard Disk a 5.9, but Graphics and Gaming Graphics only rate 1.0.

The same system, with its original hard drive, rated all 5.9. It runs 3D games well, and has no issues.

I can only think that the video card driver is somehow not operating properly, and I don't know what to do.

Original specs: Intel Quad Core 2.33Ghz, 1G DDR2 RAM X 2, Western Digital 640G SATA Hard Drive, GeForce 9800 GT PCIe Video Card.

The spare hard drive with the clean install and graphical issues is a Seagate 160G SATA.

Any help appreciated.

Had a similar issue in the past, reinstalling all the latest chipset drivers from your motherboard makers website fixed it.
