I think you have a Intel GMA 900.
Disable Windows 7 Aero. If you have a driver for Windows Vista try to install them under Windows 7.
You can buy any PCI Graphics card that supports Windows 7 and is not to big for the Case.
Before you buy any GPU for this old PC check the Motherboard for bad caps.
Hello rx64error, I do have the GMA 900, plus a Dell DV051 motherboard with A04 bios. I understand windows 7 has a ton of drivers, but why would I install a vista driver for win 7? It may be obvious for more tech-savvy folks, but I'm a bit confused. And to that point, what would be "caps" on my motherboard?? Sorry for my noob-ness, and thanks for your help!
by "Caps' he referring to Capacitors that sometimes go bad (explodes open, come loose, burns up, etc).
Went to Dell Support for your Computer Desktop PC and opened the manual: https://downloads.dell.com/manuals/all-products/esuprt_desktop/esuprt_dimension_desktops/dimension-3100_service%20manual…
According to the manual you have PCIe x1 slots. So you will need a PCIex1 GPU Card to install. Found some but not sure if it has Windows 7 drivers:
This is a AMD Professional card which is expensive but uses PCIex1 slot: Amazon.com: ATI FIRE MV2450 PCI-E X1 512 MB Video Card: Electronics

Any chance you have a Micro Center near you? They have used refurbished PC's that would run circles around what you have starting around $125. I would look into an avenue like that before spending money on a graphics card that won't help you in your next pc.
Thanks for this advice, pokester! I do not have a brick and mortar store in my area (I live in South Carolina), but their online store is an option. Based on what I've been finding on the net regarding my issue - that are mostly years old, and there's really not a lot of positive confirmation that E310's can even be upgraded successfully - and that not just finding a compatible card but also possibly finding an adapter slot and a power supply upgrade at the minimum, the costs may end up reaching the levels of what I've seen some of these refurbished PCs are being sold for at Micro Center.
So I most likely will research that option instead, and just use my E310 until it fades away, and salvage what parts I can from it (500GB HDD, 2GB RAM, etc.). And then save up for a complete new system more to my specs. Thanks for all of your help, folks!
