Win2k / Viper II / K7M / Driver Issues

I'm new at this operating system and heres my prob. I boot normally and I get the dreaded Blue Screen of death with info that follows:
***STOP: 0x000000BE (0x8052A66A, 0x0052A121, 0xBFA87F9C, 0x0000000B)
An Attempt was made to write to read-only memory. This driver may be at fault:s3sav2km.sys

***ADDRESS: 8052A66A base at 80400000, Datestamp 39760637 - ntoskrnl.exe

Heres what I have. 128 Megs of ram running my virtual memory at 192MB. I have installed the AMD751 latest drivers that come with the 4in1 driver package. Minus the installation of the AGP because the only VIA chipset I have is that 686A series. I also installed AMD's 751 Mini Port Driver for Windows 2000. All drivers I got are Windows 2000. In addition to that I installed the win2k Registry setting for AMD AGP. Now after doing all that. I started getting that dang Blue screen and I have to boot into VGA MODE under the advanced start-up. Uggg.. Evil I say. Other than that I have everything else updated also. I guess my question is.

How can I remove the Registry Key for AMD AGP? And the AMD Mini-Port Driver? These were both listed as win2k files so I snagged em and installed them now I'm paying for it. Should I just re-install the operating system. I'm really really scratching my head on this one. I would like to upgrade to a 133 Mhz Bus Motherboard but I'm low on funds. I'm also getting a CAS2 PC-133 128MB DIMM for it also to see if this helps with paging issues. Well thanks in advance for the info. Gotta do some research meanwhile.
