[SOLVED] As soon as i open task manager. CPU usage is high and then it dips back to normal.

[InfuriatedFrog]

So, I had my motherboard replaced. I installed the wrong drivers earlier and then installed the correct ones soon after. These past few days, as soon as i open task manager. CPU usage is between 60% to 80% and then dips to 1% to 10%. I thought my PC was cryptojacked. I ran malware bytes and bit defender. they found nothing. I've searched through many forums. Still i am unable to fix this issue. Please help me out. Sometimes it is system interrupts taking up a lot of CPU.
PC specs-
Ryzen 5 2400G (no overclock)
GTX 1050ti Mini (no overclock)
16GB DDR4 ram (XMP enabled)
Gigabyte B450M-H
550W PSU
128GB boot SSD
2TB HDD + 1TB HDD
Help would be very appreciated. Thank you

That's pretty normal upon startup task manager generally takes up a lot of CPU resources. This is perfectly normal and unless your pc is running slow all the time you are fine. This happens to me too.

Its not only task manager. A lot of times "System Interrupts" shows up taking almost 90% CPU Usage

Okay now that sounds a bit funky, so do open task manager and see a program called "system interrupts" taking up your CPU usage or what?

 

[InfuriatedFrog]

Yes, system interrupts shows up for a couple of seconds taking up a lot of CPU and then goes back to normal

Weird. Have you tried clicking on it and scrolling down to open file location, then click on it and try to delete or at least see what "system interrupt" is.

System interrupt is a normal process by which your CPU communicate with other hardware parts of the system. Therefore perfectly normal when starting task manager.
It's only if is this process keep using high CPU time for a long period that it might indicate a problem, as a faulty hardware mighty have problem to communicate with the CPU. But if it is a short burst when opening task manager is just normal.
