I have a Dell Studio XPS 1640 Laptop
It has an ATI Mobility Radeon HD 3670 graphics card
I want to upgrade from 64 bit Windows Vista Ultimate to 64 bit Windows 7 but it says there will be a compatibility problem with the graphics card.
Is there a fix before I do the upgrade?
How hard is it to change out the graphics card?
Most likely, it means that a graphics chip driver update will be needed.
There is a difference between upgrade in place, which will preserve your apps settings and files, and a clean install.
If you will be doing a clean install using upgrade media, you might want to read this article which describes the issues. http://winsupersite.com/article/windows-7/clean-install...
Sometimes upgrade in place will have problems that are carried forward from problems with vista.
Really, a clean install is best.
May I suggest that this might be a great time to replace the laptop hard drive with a SSD. It will transform the performance of the laptop.
