Hello,

 

My current CPU usage hovers at around 18-25% between the processes of "System" and "System Interrupts". It's mostly "System" that takes the lion's share of it though at 14-18%.

 

Anyone know how to fix this or possibly how to go about diagnosing this issue? My CPU's constantly running at max speed. The escallation happens after some minutes from boot.

 

Thanks for your time.

Start by opening up Task Manager, click on the "More details" button

Then click on the Performance tab

At the bottom of the page is a link to "Open Resource Monitor" - click on it

 

It should open to the CPU tab.

check there to see what's consuming the most CPU (click on the column header for CPU and then for Average CPU to sort them)

Let us know the image names associated with the most consumption there.

Thanks for responding.

 

I followed your instructions and it's still "System" and "System Interrupts" in the Resource Monitor.

"System" load bounces between 8-12 and 'System Interrupts'  7-12.

System and System Interrupts aren't the problem (most likely it's 3rd party programs using them) - what other image names take up a lot of CPU?

 

Have you scanned for malware?

Yeah, I figured as much as they're required processes which is why I'm asking how to diagnose this. In the past, I would just systematically go down the list of processes and disable 3rd party components until the system normalized. This doesn't seem to work in this particular case.

 

The following is a list the known 3rd party components currently running in the background:

 

1. Synaptics

2. Realtek

3. SoftEther VPN

4. ibVPN

5. Intel Video

 

I've disable everything individually that I know of except for the Intel video compnents and the CPU Idle's still high. The 2 VPN components are relatively recent and the CPU idle was already high previous to their installations.

 

Also, to directly answer your 2 questions:

 

1. No other processes are using up any notable (>1%) CPU usage while idle. The 2 culprits I mentioned pretty much takes up the entire CPU usage.

2. No, I have not done a thorough AV scan of my device in over a month. Currently, the sole AV I have is the built in Defender. I do, however, keep my entire system updated.

 

Would it be satisfactory to just do a thorough scan with Defender? I ask because I've been on this site before for other malware fixes and I was always asked to do a whole series of tasks.

 

I'm using a stock HP 15-d035dx if that makes any difference.

 

 

Thanks again for your time Usasma.

I'm not a malware expert, so I'll only ask for limited scans.

If I think you have a problem - I'll ask you to post over where the malware experts hang out.

 

Here's a list I got from US Cert for anti-malware scanners:

 

F-Secure

https://www.f-secure.com/en/web/home_global/online-scanner (link is external)

 

       McAfee

       http://www.mcafee.com/uk/downloads/free-tools/stinger.aspx (link is external)

 

       Microsoft

       http://www.microsoft.com/security/scanner/en-us/default.aspx (link is external)

 

       Sophos

       https://www.sophos.com/en-us/products/free-tools/virus-removal-tool.aspx (link is external)

 

       Trend Micro

       http://housecall.trendmicro.com/ (link is external)

 

Try this stuff (the first one is sort of old):

Ok, the last sizeable patch released for W10 seems to have changed my PCs behaviour. It's no longer consistently hovering at a high load. It still periodically happens but I'm still diagnosing how/when it happens.

 

For now, please consider this thread closed. I'll just re-open another if it's still problematic for me.

Thanks for your offered assistance Usasma. I appreciate it.
