Windows 7 Video Driver for IBM ThinkCentre 8424-3BM
IBM does not have a Windows 7 driver on their website for this machine.
Instead, follow the steps at http://forums.techguy.org/windows-7/943982-solved-windows-7-driver-intel.html to download the Driver update for Intel(R) 82915G/GV/910GL Express Chipset Family from http://catalog.update.microsoft.com/v7/site/Search.aspx?q=Intel%2082915G%2FGV%2F910GL
Extract the contents of the “Cab in a Zip” file, then tell Windows 7 to use that driver even though it doesn’t want to.
(Only tested on 32 bit Windows 7.)
