Question System Interrupts 100%---or not?

[Beachhead1985]

Noticed my PC running slower than usual, brought of task manager and it shows CPU @ 100% due to 100% system interrupts.

Searched that on my phone and it gave a number of options; I chose to run a hardware diagnostic, as that seemed to be the worst case scenario. That came back clean.

Malware sounds unlikely...But I am running the scans now anyways.

CCLeaner says I have out of date drivers.

Device Manager says I don't. Just as well, can't find drivers for those online anyways.

Task Manager no-longer reports the problem.

Computer seems to run fine after the restart. What is going on here?

Thanks for your time.

Hm. Using the PC for a bit again and it is back to slow-as molasses and 100% system interrupts

Try this, it replaces all system files with new one without damaging your programs and data.

This explains what system interrupts are,

As it says, causes to that are many. Hardware failure (or about to failure) is one option. I had high, 80-90% system interrupts when my HDD was giving up the ghost.

Since you didn't list your system specs (unless it's those in your sig), you have old PC, that may give up the ghost soon. If you have HDDs, better to check their status. Could be that one of them is failing.
