|Download the desktop drivers |
Extract the package, I like WinRAR www.rarlabs.com
Go to your device manager, select your video card, right click and update driver.
Now Browse for the driver, let me pick form a list, click have disk, now find the ini file of the driver in the stuff that you extracted.
Make sure it is for the HD 4250, Windows will bitch about the driver, just click next.
And see if that works.
There is another way of editing the driver files and putting in your hardware ID and such to get the full cat control center to work, but who needs it.
