Hi, first time posting here, sorry if this is the wrong forum and/or if I'm doing this wrong.
That said, so I recently did a clean install of Windows 7 because my hard drive was filled to the brim and my external hard drive was getting repaired, so RIP all my files. Most of them were useless, however.
With that said, I tried setting up Sonic CD's video via Steam and....well, I'll let the error log speak for itself for now, which is here: http://pastebin.com/Div5iRnN
If I click details, I get this: http://pastebin.com/P96anxEQ
I then tried using an official NVIDIA driver updater. GeForce Experience, specifically. It then says, despite my video card being a NVIDIA GeForce 9800M GS 512 MB card, that the graphics driver isn't supported, when it was supported before I installed Windows 7.
So, I know I'm stupid for not backing everything up, but that's beside the point. What happened and how do I fix this?
