Thanks folks. Ok so 64 Meg should definitely be enough. The USB contollers ( both ) are IRQ 16, Audidgy2 ZS NB is IRQ 16, NVIDIA GeForce Vid card is IRQ16.
I'm using 3 sound cards
1. Creative Extigy---USB
2. Audidgy--PCMCIA
3. Realtec--- Built in.

I'm going to uninstall all and see what happens.
The Toshiba is a little dated so not sure about updates being avaiable.
