What would cause the CPU Usage to jump up to 90% whenever the keyboard keys
are pressed for any length of time. Even just typing this to quickly makes
it jump up to 30%+??

Well my motherboard make is MSI (Micro-Star International) MS-6533.

I had a look in BIOS but not being to familiar with it decided against
changing to much. I no longer think the network card is the problem. Even if
it is using the same RIQ as the Audio. What I have discovered is when I go
into Windows Task Manager and click on the Performance Tab, pressing down on
any key makes the CPU Usage jump up to over 90% until I release it again. So
I'm thinking that the keyboard is not only interfering with the sound but
but somehow slowing down my whole operating system.

No the sound doesn't stop it actually slows down breaks up and stalls or
pauses if you like, until I release the key I've was pressing then it
continues as normal.

I did as you suggested and put a music CD in my drive. It played fine until
I pressed one of the keyboard keys. Then it just slowed down and stopped
until I released the key again. Placing headphones into the headphone socket
made no difference.

Seems to be fine can't see anything wrong with it.

That might be just a little beyond me. If I took my system apart I doubt
very much it would go back together again and work at all!
