diagnosis problem

Hi all,

I have a PCMCIA card (WPC54G v3 linksys wireless-G notebook adapter) used for my internet connection. I have a dual core processor with Windows XP sp2 uptodate. I installed my wireless adapter on the notebook and got internet connection easily. But the CPU usage showed by the task manager was indicating me 50% (one of the two processors used all the time), while, at the same time the idle process was using 99% of the CPU. Googleing across the web, I downloaded "Process Explorer" which is like the taks manager, but with a little more details. It showed me that most of the CPU usage came from hardware interrupts. As a matter of fact, when I take off my network wireless adapter, the CPU usage drops down to almost 0%. And when I put it back, the problem comes back.
Googleing into this a little bit more, I see that disabling peripherals one by one would pinpoint me the culprit. As I know it is related to my adapter, I sucessively disabled all peripherals linked with the adapter. I even disabled the hidden peripherals. But the problem stayed. once all my peripherals were disabled, I shutdown my computer and when it came up, of course, the problem was gone. There is around 10 peripherals related with the adapter, and disabling/enabling a peripheral takes some time. If in addition to that I have to do a power off power on each time I test a peripheral, it will take me hours. Would you have any hint on this ? Any tool that could help and go into more details into the hardware interrupts ? Any method to track this problem down would be much appreciated.

Of course, I forgot to say I have updated all the drivers from linksys website. And I also tryied to disable all the running services I could, but none of the stopped services could stop the hardware interrupts problem.

Alexandre.
