I've installed a ti4200 as well as a SB Live on my system and I'm experiencing a lot of instability, as in my system crashes after about 10-15 minutes of internet browsing and mp3 listening, but runs 3dmark fine. I think it might have to do with the fact that I've only loaded the 4-in-1 one AGP drivers and not the amd miniport thingy (from what I've been reading). Should I uninstall the 4-in-1 AGP bit (how?) and does this sound like it could be the prob? Thanks.
