Uncertain on where to post this so the hardware forum will probably be correct.

Found my pc running at a high CPU earlier, did virus scans etc and nothing came up, got ProcessExplorer and found that there was 'Interrupts' running at 45% or so. My problem is that I dont understand about hardware or how interrupts are caused, i recently (week ago) installed a wheel for my computer but the interrupts only started today. Can you help me?

Used the winhlp link i found elsewhere and it appears to have sorted it. The IDE drives were running PIO and after doing what they said they're in DMA mode now.

Hello and welcome to Bleepingcomputer.

When you say a Wheel is this a steering wheel for playing a driving video game of some sort?

Interrupts are explained at these web sites.

http://www.duxcw.com/faq/irq/irq.htm

http://en.wikipedia.org/wiki/Interrupt_request

Once you have read those pages above you now can understand that each piece of hardware in your computer needs its own special attention from the CPU, so it is assigned what is called an Interrupt number. Some IRQs are reserved for the system, others are shared among the hardware that requires an IRQ.

More than likely, the wheel I installed was a G27 Racing Wheel and not one for a hamster. I've checked on the Process Explorer and its all acting how it should, the Drives that were PIO are now on DMA, so thank you for the links explaining them as well :thumbsup:

You are most welcomed! :thumbsup:

In case someone sees this thread I will offer the link I provided to the other member in that other thread here in this thread. This way other members will know what link helped you resolve your problem here in this thread.

Here is the link: DMA reverts to PIO mode.
