SiS 5597/5598

I am trying to upgrade my family's Packard Bell 850 computer. I am attempting to install a Monster 3D2 into it. I tried before and it worked fine. Problem is I attempted to install new drivers for it when I got a fatal exception error in windows and when it restarted windows explorer crashed.

In the process I had to reinstall windows and as a result I lost all my drivers. Last year I tried to get this system to run Quake 2. All I would get is a blamk screen which is happening now. Problem is the drivers I downloaded a year ago are no longer there and the ones posted don't work. I have tried tech support from packard bell and SiS. The tech from SiS told me that Quake 2 cannot run on this chip but I know he is dead wrong. This system ran Q2 in software mode for over a year without any problems. I have version 4.10.01.0905. I need a version between that one and the current one. Any help would be appreciated because neither company has been much help.
