Solved 100% CPU usage when computer is in "sleep" mode

    I have read countless articles regarding a Windows 7 computer using 100% of the CPU's capacity, but my situation isn't like any of the others described. While I'm using the computer it's not a problem -- CPU usage rarely goes over 65% & it's usually much lower. But since it takes a while for the computer to start up I usually don't shut it down, I put it "sleep" mode when I'm going to be away for a while, but want to get back to what I was doing with one click.

    Sometimes when I get back to the computer I hear the cooling fan running as fast as it can (usually can't hear it) & when I click a key on the keyboard to "wake" the computer up I see that explorer.exe is using 100% of the CPU's capacity. I run a program called System Explorer all the time (similar to Process Explorer), which shows every program / process that's running & how much of the CPU & RAM each one is using. And every single time CPU usage jumps to 100% explorer.exe is the culprit.

    Yes, I've run anti-virus & anti-malware scans & I have anti-virus & anti-malware programs running all the time. Zero problems detected. And again, when I'm using the computer I don't have any problems with high CPU or RAM use -- it only happens when I put the computer to "sleep" & it doesn't happen every time I do it.

    I downloaded "SysInfo.exe" but it won't install due to an error I'll address in a separate post: "A Required Privilege Is Not Held By The Client." But here the basic computer info:

    Dell deskside, Windows 7 (64-bit), Intel dual core CPU, 3 Ghz, 4 Mb RAM.

    I would expect the CPU to be in high usage when waking up a system. The files that were in use, at the time of sending to sleep, must be copied from disk to the memory. This at times can take a while if a lot of programs and data were in use.

    Try disabling hibernate and see what happens.

    From Elevated command prompt
    type powercfg -h off

    While in command prompt the next command
    1. tasklist /svc /fi "IMAGENAME eq svchost.exe" > "%userprofile%\desktop\tasklistsvc.txt"

    2. Upload the Tasklistsv.txt to your reply
    I mainly use Process explorer but if you can provide a report with your program it should work

    Download Process Explorer
    https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

    1. Save it to your desktop then run it.
    2. Right Click and Select Run As Administrator
    3. In the View Menu click on Select Columns
    4. Check Verified Signer, Virus Total and Click OK
    5. Select Options Menu and Check Verify Image Signatures, VirusTotal.com > Check Virustotal.com
    6. Double Click on the CPU Column to sort by highest CPU usage.
    7. (Highest CPU Processes should be at the top once sorted properly)
    8. Wait approximately a minute
    9. Select Save or Save As from the File menu and save SystemIdleProcess.txt to Desktop
    10. Upload the file to your Reply

    On another topic you have started
    https://forums.techguy.org/threads/a-required-privilege-is-not-held-by-the-client.1208439/

    you intimate that you use this program
    https://www.reginout.com/

    If you do, then THAT may well be the cause not only of the problem on your other topic, but also this problem.
    SO the 1000$ questions are
    1. Is that reginout with its so called optimization and make it go faster - claims running on the computer

    2. What is this program please
    3.
    Which please

    I don't have any reginout software on the computer.

    > 2. What is this program please
    run a program called System Explorer all the time

    It's very similar to Process Explorer. I have that program too, but I'm more familiar with System Explorer & for all practical purposes they do the same things. See: http://systemexplorer.net

    > 3. Which please
    I have anti-virus & anti-malware programs running all the time

    For quite a while I've been running Advanced System Care Ultimate which includes a "Real Time Protector" & IObit Malware Fighter. It's been @ least 10 years since I had a virus, trojan horse, etc. & I've never have had one on this machine. Periodically I run Malwayebytes & it's never turned up any malware.

    Forgot to add that I have hibernate disabled. And that I'm experiencing just the opposite of this: "I would expect the CPU to be in high usage when waking up a system."

    System Explorer puts a little computer screen in the taskbar which shows a graph of CPU usage -- when it's solid red CPU usage is @ 100%. Also, when you point your arrow @ that little screen it'll show you the top 5 programs which are using the most system resources. When I touch a key or move the mouse to wake the computer up & immediately point to that screen I see that it's solid red & that explorer.exe is what's causing 100% CPU usage.

    And you can also see the CPU usage drop like a rock as the machine is "waking up" -- explorer.exe stops using a lot of the CPU & usage typically drops to around 6%. Then as I start programs & open files, the CPU & RAM goes up & down just as you'd expect it too -- no problems whatever while using the computer -- just after I put it to sleep I'll hear the cooling fan speed up to as fast as it'll go, which tells me the CPU has gone to 100%.

    Attached is the System Idle Process text file. Sorry for the earlier copy & paste of those results -- chalk it up to "brain fade".

    Uninstalling SecureAPlus did solve the other problem, but had no effect on this one. But after using diagnostic startup & then Services, going thru every process, disabling some, setting others to manual & leaving some on automatic, 1/2 of this problem appears to be solved.

    When I put the computer to sleep, come back later, wake it up & immediately check System Explorer (or Process Explorer), explorer.exe is running, but CPU usage is low. But if I walk away from the computer & let the computer cycle thru my screen saver (after 10 minutes) & turn off hard drives (after 15 minutes) settings, CPU usage will still go to 100% & explorer.exe is using the vast majority of the CPU. I can see that by moving the mouse & immediately checking System Explorer (or Process Explorer).

    It makes no sense to me that anything would run the CPU up to 100% when the hard drives aren't even running! And I have no idea what explorer.exe is doing after the screen saver comes on & the hard drives stop. But I usually put the computer to sleep when I'm going to be away for more than 10 minutes & now that seems to be working the way it should.

    Thanks again for everyone's assistance.

    Try changing your power plan to high power and see if it changes anything.
