Solved Hardware interrupts process hyperactive

September 18, 2012 at 20:40:23
Specs: Windows XP, x86 1995 MHz
I noticed through looking into the processes running on the computer that there is too much activity in the "Hardware interrupts" which slows down the computer significantly. I didnt add any new hardware recently so I dont know where did that activity come from. How do I trouble shoot that?

My money would be on your network card driver. But it could be any of your drivers; check that they are all up-to-date.

Yes they are already set to DMA

Your Graphics card, you keyboard, your dial up Modem if you have one, Your Ehternet card if you have one, your wireless interface of you have one .you4 real time clock, you memory refresh are all constantly generating hardware interrupts; every 15 milliseconds.

If your computers is slowing down,I should look a little further than hard ware interrupts. It is vry unlikely that is the problem.

Look in Task Manger and see which processes are using the most CPU time.

As I said earlier ,I looked at the processes and found out that the interrupts consume most of the CPU. I have a special program called Process Explorer which gives me all the info about processes. That is how I knew.

Yes it looks like the network driver. When I disabled it the interrupts slowed down. I will look for an update.

There's a slight possibility that this indicates a hardware fault, although I think it is unlikely. If a driver update/reinstall doesn't fix it a cheap replacement NIC might be the answer.
