Dell Dimension 3100/E310, Graphics/Video Driver for Windows 7 (x86 / 32-bit)
2012-01-06 Initial Post
NOTE: This was NOT tested on x64 / 64-bit systems.
I recently loaded Windows 7 Ultimate x86 SP1 on a Dell Dimension 3100/E310 and it did not properly detect the graphics card. Dell has no Windows 7 drivers for this graphics card. The system runs Windows 7 fine even though it only has 1.25 GB RAM so the only thing holding it back was the lack of a graphics driver which resulted in crappy screen resolution.
Since the system uses the Intel 915GV chipset, I looked on Intel's site. I found a driver for XP and used that and it seems to work fine on Windows 7. Just install the driver directly instead of running the installer. After reboot, you'll get some warnings to allow some of the driver-related files to run--you may allow them all. I rebooted a few times and everything still works correctly. The driver will show up as Intel(R) 82915G/GV/910GL Express Chipset Family.
The maximum resolution is only 1400 x 1050 which is less than my monitor's native resolution of 1920 x 1080 (I have a Dell P2310H). For smaller monitors, 1400 x 1050 should be fine.
Here's the driver download from Intel:
