system athlon 64 3400+ 2.39 ghz
2 GB Ram
Windows XP media center SP2
Linksys wireless G USB adapter
Soundblaster audigy 4
nvidia geforce 9400GT

I have switched video cards, tried removing soundblaster, swapped ram chips with no success.

Thanks for any ideas.

Typical of a bad sound card... I suspect your Audigy 4 Soundblaster has cooked its own goose from long use.

I tried taking out the sound card with no improvement but I didn't uninstall the just disabled and removed from the machine.

Would that change anything?
