It could be the BVision/Permedia2 overheating, a small heatsink on the
permedia2 helps a lot with stability, as does a PSU fan mounted behind the
BlizzPPC's fan, using a fan this size also helps circulate the air in the
tower.

GLQuakeWOS runs perfectly here, well almost... I'd say the problem was either
heat, or you have an early Blizz which needs a refix?

Carpe Diem,
