I just got a Radeon 9550 graphics card, and I've been having problems trying to install the thing. When I try to install it from the CD, a message pops up saying:

Severe
Setup was unable to complete installation.
Try to setup your display adapter with a standard VGA driver before running setup

When I try installing it with Windows New Hardware Wizard, I get the message:

An error occured during the installatioin of this device
- The data is invalid

I really need help, what should I do?

This is the data invalid solution - Data invalid solution
For modem read video/graphics/display That might be allow you to install.

You might have toboot into VGA mode(tap F8 AT Startup,select VGA mode) and then try installing.

Further possibilities if that didn`t work -Make sure your system is free of any remnants of previous video card drivers
use this - Driver cleaner If necessary.

If you get problems look here - Helpful link and Helpful link and Helpful link

Don`t say you haven`t got enough information

Thank you very much, it worked! After I sorted out the "Data invalid" problem, I was able to install everything else. Again, thanks!

I would like to know which of those instructions worked for you, i tried all of them and none worked.
