vreg,
Go on-line and download from ATI site the last Catalyst drivers for the 9250 as sharkfood pointed out above.
Go into Device manager/Hardware/Display Adapters. Righ click on properties. Driver tab. Update drivers. Now, DON'T use the cd that came with the vid card. Just point (using browse button) to the folder/file you downloaded. If it is a zipped file you'll have to unzip it in an empty folder first. Then point the browser window to the setup file. Windows should find it from there.
