Interrupt - Wikipedia, the free encyclopedia
In computing, an interrupt is an asynchronous signal indicating the need for attention or a synchronous event in software indicating the need for a change in execution. A hardware interrupt causes...

I've got a program that shows about 80% "Hardware Interrupts" going on while the new application is opening. I've been trying to fix it for 2 months with no success. There are no baddies on the computer for definite.

1. First acquaintance with hardware interrupts. ... Begginer's guide. This is to describe what are hardware interrupts and how are they processed by an IBM PC compatible. If you have already worked with handling hardware interrupts skip this part.

I must confess I don't understand what the hardware interrupts displayed in Process Explorer are and how they work. I'd like to know if it's normal for hardware interrupts to ever spike to 50% levels (this is on a dual...

The Programmable Interrupt Controller (PIC) handles hardware interrupts. Most PC's will have two of them located at different addresses. One handles IRQ's 0 to 7 and the other, IRQ's 8 to 15, giving a total of 15 individual IRQ lines, as the second PIC is cascaded into the first, using IRQ2.

Hardware interrupts are generated by hardware devices when something unusual happens; this could be a keypress or a mouse move or any other action. ... A standard IBM-PC has two interrupt controllers, that are responsible for these hardware interrupts: both allow up to 8 different interrupt sources (IRQs, interrupt requests).

When an interrupt request is serviced, the hardware automatically turns off a flag thus blocking further interrupts from being recognized by the processor (i.e. other interrupts are "disabled").
