I have that motherboard with a K6-2 550, 256 megs of ram and an Le(hyper enabled at 190mghz). It runs rather more choppy than I had hoped but it's compatable with the few games that I play(Diablo2, Empire Earth...). Maybe you have something enabled in your bios that the Le doesn't like...or maybe you didn't remove the drivers of whatever video card you had in there before,(some say v3s' drivers can cause havok, though I've seen nothing of it myself).
