Bad Pool Caller

I have a customer who is running a dual P3 600MHz with XP pro and he just got cable internet, now whenever he is downloading large files he gets a BSOD with a Bad Pool Caller Error.

it is a SuperMicro P6DBE Mobo with 512MB of Crucial Mem in 4 sticks, an original Radeon with a TVwonder (non-VE).

any thoughts???

The only change has been the cable internet, it's a Surfboard 4102 modem and we've hooked its hooked up via USB.

Certainly looks like a driver issue ATI Radeon have been guiilty of this... Especially the powered by drivers. Try updating the TV wonder drivers.
