ok. Mine is a Nvidia System, AWRDACPI MOBO, Phoenix Award Bios. It it has an inbuilt Nforce 2 MCP. 1 gig of ram. AMD Athlon XP 2500+ CPU.
Once i installed windows 7, it didn't recognize the inbuilt NForce. After investigating o found that there were no drivers to be found.
So instead i got a His Radeon 512mb 3650 AGP graphics card. Every time i try to install a driver for it, and then restart my computer, Windows fails to load. The computer reboots and i have to use system restore to load windows again.
