Hello, I have noticed that, for the past few weeks, my procexp has been showing the interrupts using upwards of 75%-100% of my CPU. I know that the interrupts deal with the hardware of your computer.
I have been searching around to find a fix and the most common solution was to switch the IDE channels to DMA mode (PIO mode caused the high cpu usage) but all of mine were in DMA mode. I have used driver sweeper programs to remove my video card, modem, etc.. But I have had no luck. I've switched out hardware, changed bios settings, booted up with any startup programs.. Nothing.
I have scanned my computer for spyware, adware, virsus, trojans.. Etc.. I had a few pesky adwares installed but nothing significant enough to cause this problem.
I came across a program, made by microsoft, that would watch the interrupts and log every driver that was using the CPU time. I have uploaded the file below. Hopefully you can make better sense of it.. It seems to me it MIGHT be a video card issue because it counted A LOT of ISR with the "VIDEOPRT.SYS" driver? Possibly my video card is faulty?
Anyways, if you have any insight into this that would be amazing.
Thank you very much!
