Did you install the via4in1 drivers correctly along with the Radeon drivers? This the regular method i go about it: service packs (if any) -> via4in1 -> video card drivers -> directx. I had frequent lockups with the Radeon LE also. After editing the registry, reinstalling drivers several times over, and reading up on a million forums, I ended up with the solution that would have saved me the most headaches: format and install windows again.
well i do have everything installed that you both stated. i guess i'll be reformatting and reinstalling windows 2k again. damn, was hoping i wouldn't have to do that. well how about the processor problem? the BIOS knows that it's an 800mHz. any reason why 3dmarks doesn't?
