Hardware acceleration error after upgrading to windows 7

What is the make/model of your computer?
We need that info to show you where to get your drivers from.

In all likelihood, a simple upgrade of the GPU drivers, would fix this problem. Go to the website of the GPU chipset maker, such as nvidia.com or ati.com, and download the current drivers for your video card and operating system (32 or 64 bit Win7 in your case). This should take care of the problem as you are likely using Win7 provided generic video drivers now. Good luck!

Gandalf I dont know how to find that stuff.

Download/install/run Belarc Advisor. It will tell you a lot about your computer.

CPU-Z will also help gather this info:

Hello Heather15,

It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibilty.)

There is a pulldown from which you can choose "hardware" and "software".
There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site:

In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!
As stated previously, it's best to have the Windows 7 certified drivers installed.
Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams. You may want to check the threads available there for additional assitance and support.
