I was messing around with my drivers, trying to update them and then roll back to a previous version but now I can't install any at all. I have a Radeon 3800hd card and I either get a message saying that the device isnt installed properly or say "The parameter is incorrect". What do I do know, I have no drivers installed at??

Hi C,

Try this:

1. Install Driver Cleaner.
2. Uninstall current drivers (add & remove programs).
3. Go to the Windows device manager and make sure the driver is gone, if it is still there, right-click on it and uninstall.
4. Reboot the computer into Safe Mode. If Windows try to re-install the driver, select cancel.
5. Run Driver Cleaner and select the driver you want to remove from the drop down menu, proceed with cleaning.
6. Empty the recycle bin and boot back into normal Windows, install drivers.
