I just purchased Doom 3 and upgraded my graphics card from a Geforce 4 Ti4600 to an ATI Radeon 9800 Pro – 128MB RAM.
I have an Asus P4SDX motherboard - 2.53 P4 with 1Gig Ram.
SMARTGART was not allowing AGP acceleration. Read an article that I had to upgrade to latest graphics and AGP drivers. I have the latest ATI drivers.
I went to SIS and Asus and found the latest SIS655 AGP drivers. I installed them and all went smooth.
I was then able to set AGP to 8x. All happy right? No! After about 3 minutes playing Doom 3 all hell broke loose. System froze! Messages came up! Generally bad things!
Had to go back in to the system through safe mode and uninstall the new drivers to regain system stability.
I flashed the BIOS so that is up to date.
What do I do now?
