Windows 10: Slowdown of System, High CPU, Cannot Find Source of Problems

Hello everyone! I have been having a rather infuriating/frustrating problem on my system since early yesterday. I'll just give a timeline of all that I have done in an attempt to fix it and how/when the problems appeared.

First off, I opened my computer after having it been asleep all night; everything was working fine until I realized that my sound volume was stuck at a high level and no matter what I changed the volume to, it would not go down. Having had issues with my sound drivers before, I solved this by reinstalling the sound driver. I figured this would be the end of my issues for the day and restarted the computer to finalize the installation. Then windows installed updates, and when I got back into the system, I realized something was wrong. I have Advanced System Care 9, which comes with a real-time monitor of system usage (RAM and CPU), and I noticed that the CPU usage was much higher than it should be--usually it will be around 1-5% when I am not running anything (or just a few programs), but instead it was using 20-90% CPU, and the RAM would not go any lower than 24%. However, I had had this issue before; Bitdefender Antivirus had started acting up a few days ago using up 90-100% CPU, and I had caught it using Microsoft Process Explorer. Removing Bitdefender solved the problem. So, naturally, I went to the process explorer to check what was using so much CPU again. But this time--nothing. The windows process explorer showed nothing using that much CPU. From there, I began to notice the rest of the problems: many functions of the task bar would not work, such as any of the toolbar icons, or the windows icon, or Cortana. Firefox would not open, either, and I could not get Steam to connect. Also Ctrl+alt+delete did nothing but bring up an endless black screen, as did restarting. The only way to reboot is to force it by pressing the power button. Therefore I could not reach safe mode. From there I ran a myriad of virus/malware/adware scanners/cleaners/optimizers, none of which found or did anything to fix the problems, though my computer is now squeaky clean otherwise! Eventually I managed to get into safe mode by a very finicky method, which was by turning the computer off during startup which made it do a startup repair next time it turned on, from which I was able to enter safe mode. And in safe mode--everything works. None of the described issues happen there. I am able to use all the windows features (aside from those blocked in safe mode), ctrl+alt+delete and restarting function properly, and I am able to connect to the internet and use firefox, everything works. So this means that there is something there causing the problems, and it is being blocked by safe mode, but I cannot find it! After running several more scanners, all of which found either nothing, or only small innocuous things, I ran Microsoft Safety Scanner, which found a "severe" trojan which was (I believe) called Dynammer!ac, and I figured this must have been the culprit--but no. Restarting and returning to normal mode resulted in the same problems occurring. Since then I have uninstalled/reinstalled a few drivers that were suggested to me to try, such as sound (the one that I had to replace before the problems started), and the display drivers, none of which fixed anything, either.

So, now feeling like I am pretty much out of options, and very frustrated at this issue being so hard to find or pin down, I've come here seeking assistance. If anyone has anymore ideas for me to try or of what may be causing these issues, please let me know and any help at all is very much appreciated! Thanks in advance!

Simple......high cpu usage means high heat in the processor!!! Lift your laptop off of the quilt and put it on a small bed top table with a FAN KEEPING IT COOL!!!! Your slowdown problems will disappear.#

 

Parked cores? Windows 10

At the time of your image the cpu was only 16% in use, so the cpu is not the source of the

perceived slowdown of you machine.

When more cores are needed they will kick in automatically.

Core parking is an important means for using less power, and helping the cpu to run cooler.

Unparking cores will not improve performance, in most scenarios.

.

 

When you lower the volume , does the slider move up by itself, in front of you ? I assume your using a mouse for that. Let me know

 

Oh, yes it does; the sound works fine now, and I can see/use the sliders when they work, sometimes they are sluggish or will not show up, just like the other windows functions I mentioned; it's very inconsistent as well, always a different set of working, half working, or not working functions; tho restarting and Ctrl+alt+delete are always broken.

 

Ok Flutters, sorry I didn't get back sooner. I think the wheel on your mouse ( do you have a wheel) is causing the problem.
Try unplugging the mouse dongle if wireless and reboot the system without the mouse, or anything else you might have plugged into a usb port. Let me know if the problem persists using just the trackpad.
I had a similar problem and the wheel on the mouse was the culprit. If you accidentally tilted the wheel left or right it may have gotten stuck.

 

Oh, I think we may have misunderstood each other; the sound is fixed and I change the volume using keyboard buttons, not the mouse. I use a trackpad, as well. The major issues are the high CPU usage and the sluggish/non working nature of a lot of features on the task bar and with internet browsers.

 

Also after you reboot let the system power up for a few minutes and right click on the start window, go to command prompt (admin) left click and when the window opens, at the prompt type sfc/scannow and press enter. let us know what the outcome is. It will take a few minutes to run. be patient
Leave the mouse unplugged

 

Thanks, I'll try that now! *Smile

 

Okay I finished that, and the report says "Windows Resource Protection did not find any integrity violations."
So it didn't find anything, just like everything else I have tried thus far. So frustrating!

 

That's good, but you should still be able to use the slider for volume control. Using the trackpad for the slider volume, without the mouse plugged in works?

 

The next thing is to boot into safe mode and see if a rouge program is causing the problems...have you tried safe mode yet?

You may have a virus also...have you run Malwarebytes Free?

When your in Safe Mode with networking download the free Malwarebytes and run a scan
