High CPU usage when idle and when task manager is closed cant fix with scan

[pdeebq]

I've seen similar posts but cant fix my issue.  CPU usage high for a split second when opening task manager then it drops to <5%, sometimes its at 99%, sometimes 65% but no matter what I can't get it to stop. I've even noticed it when going completely idle with nothing open.  I thought it could be a cryptojacker/bitcoin miner but malwarebytes, adwcleaner, AVG and the like wont detect any problems.  I've ran 10 + scans on all of them.  These are the notes from the last malwarebytes scan i did just a few minutes ago with 0 threats detected.

Can you let me know which scans to run and which documents to attach to better help you understand whats going on?

 

Thank you !

Hello pdeebq and welcome to Malwarebytes,

Have a read of the replies at the following link, specifically the one from nukecad, does that answer your question...

Thanks,

Sadly this does not help me :/.  I can hear my computer fans increasing in speed as well. For example when i switch tabs within task manager from processes to app history (where it doesn't monitor usage). And it's not reading 100%, although I've seen that from what nukecad posted so i appreciate that update. 

I'm at the point to where I want to wipe my entire SSD and start from scratch. This would absolutely eliminate the possibility of malware, is that correct?

Ok lets continue with the following:

Download Farbar Recovery Scan Tool and save it to your desktop. Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status... Right click on FRST and rename FRSTEnglish if English is not your primary language   Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.) Make sure Addition.txt is checkmarked under "Optional scans"   Press Scan button to run the tool.... It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply. The tool will also make a log named (Addition.txt) Please attach that log to your reply. Thank you, Kevin

Hiya pdeebq,

I`m not seeing any malware or infection in your logs, lets try your system in "Clean Boot" mode and see if that males any difference..

Set windows up for "Clean Boot" mode, full instructions here: https://support.microsoft.com/en-gb/kb/929135 Basically all none MS services are disabled, see how your system runs in that mode. Does that make any difference...?   Thanks,   Kevin..

Thanks for confirming no malware is infecting my computer.  I performed a clean boot earlier this month to no avail.

My other theories were to replace old hardware (that needs replacing anyway):

Power supply: Occasionally makes a terrible grinding sound from the fan which is fixed with a.. "love tap"..

CPU: It's been with me through 2 PC builds, and stressed from time to time more so than the average user I would say what with streaming for some time, producing music in ableton etc.

Motherboard: has also been with me through the 2 builds and is out dated to say the least.
 

From your knowledge could any of these be contributing to my problem? It's my last resort to update all of those with the addition of an SSD M.2 to boot off of (my current motherboard does not support M.2)

[kevinf80]

What you describe sounds like a new PC is needed, all of your hardware has been round the curcuit a few times. If clean boot makes no difference I would certainly think about an upgrade... Replacing hardware or upgrading is definitely in need of consideration..

If your Motherboard and CPU have seen better days then maybe a new PC is the way to go...

Alright, well thank you so much for your quick responses and sharing some knowledge with me.  I guess the good news is I already have a 1080 so I won't be completely broke. Have a great night Kevin. Cheers.

I`m sure you`ll do what is needed, comeback anytime.....
