Could Knoppix not be crashing because it is more stable, or because you can't run as many programs as you normally do with XP/98?
I'm not surprised that you haven't heard of the RAM voltage, it's nowhere to be found in the ASUS documentation. I found this thread ( http://forums.amdmb.com/showthread.php?s=&threadid=113092&highlight=a7s333+ram ) with the undocumented jumpers (JP1 and JP2) that can set the vdimm. The default should be like 2.6, try 2.7 or maybe a little higher, but only long enough to see if it doesn't crash like it normally does (the post you're looking for is a little further down the page, the images are broken for me, but someone described its location midway through).
You wouldn't happen to be using a RAID, would you? It seems like people are generally having problems with the RAID controller on this board, if I recall correctly.

Maybe you're required to raise the Vcore voltage to 1.65 V (if T-bred, Barton or Thorton) or 1.75 V (if Palomino).

It's also common for PCs with unstable processors to run stable under Windows 98 SE, but crash with a BSOD repeatedly during gaming under Windows XP.
Sometimes, when the processor is unstable, the game will run fine, but if you press buttons rapidly in a game, the game will lock up. That's a symptom I observed before a while ago.

The system should set the vcore on its own, but there is an overvolt jumper somewhere on the board that he can raise it with. I guess if the processor was causing the problem, he'd need to raise it, even if it was already stock.
Eagle:
If you want, try running <a href=http://www.memtest86.com/#download0>memtest86</a> before playing with the voltages. It should tell you if the memory is bad or not.
One thing I did read, though, was that certain revisions of your motherboard had the RAM running at 2.8v (stock on almost all RAM is 2.6, this is way too high without cooling). You may check to see where your J1 and J2 positions are, and compare them with what they should be (1-2). If it was running too high, there is a good chance it damaged the RAM unless it has heatsinks on it.
It looks like ASUS didn't do a good job of mounting the northbridge heatsink (it's just sitting on top of the northbridge with no thermal compound). I guess it's possible that the northbridge could be dying...?
Here is the FAQ if you want it: http://forums.amdmb.com/showthread.php?threadid=155944
You may want to try what RJARRRPCGP is saying first (check vcore, raise it a little, i.e. by the smallest increment at a time) to see if the processor is causing the problem. You should be fine with raising it to 1.8v or so.

Don't raise the Vcore to 1.8V unless you're overclocking the processor.

Yes, that would be for normal circumstances, but if there is something wrong with the processor, raising the vcore will test for its stability.
If there is something wrong elsewhere, it will do nothing to it.
He has adequate cooling for such voltage, anyway.

Ive already run memtest a long time ago ( I think I mentioned it in the original post). As for all this jumper pulling etc. I am afraid I must refuse to do this. Even if it is something bad on the motherboard or processor, I cant afford to replace it right now, and I'm afraid I could make it worse and my computer would be unusable. As for those links you gave me, thats the wrong motherboard. I have a SiS chipset, not a Via

Oh, ok. I must have missed the bit about memtest.
Sorry about the wrong links, someone on that forum linked to that page when I was looking at info for your motherboard. I guess I wasn't paying much attention to it. :-\
I'm out of ideas, maybe RJARRRPCGP can help you.
