System Internals - Hardware Interupts CPU time - PC running slow

Client has problem with PC. Going very slow and even the mouse movement is jerky.

Could see nothing in task manager process list. Was showing quite high on system idel time actually.

But then uses System Internals and that was showing "Hareware Interupts" as running at 40-50%.

This led me to think that something in the hardware is causing problems and they siad they did reently install a HP laser printer.

Have removed all perhipherals accepts for Mouse and Keyboard (also previous to this run anti spyware and other clean up programs including hijack this).

Net result is better performance but it is still not fantastic.

How can I investigate further what is causing the hardware interupt appering.

Thanks for the input. In the end the combination of things I ran (Such as hijack this, spyware removers genera lean up) and the client reported a massive improvement so no need to invesigate further really as they are happy.

So points awarded for comments as valid to solving the situation.

Didn't actually check the event logs and should have done.

thanks
