PC fan randomly ramps up while idle

The other day I spilled some water near my setup's power strip. I quickly turned it off, but after some inspection I found that no water ended up getting into any electronics. I turned it back on and everything seemed to work just fine, but I noticed that when I'm not using my computer but it's still turned on (fully turned on, not in sleep/hibernate), the CPU fan will ramp up for a few seconds and then ramp back down. This also happens when the screen is black and I make a mouse movement, waking it up. Any help would be appreciated!

    Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you.

    Here are some steps that I have compiled for you to try:

    Option 1: Turn Off Fast Startup

    1. Click the Windows Start Menu > type Control Panel > Click on Control Panel

    When you go to the control panel it may show up as the “Category” view option by default (near the upper right side of Control Panel window). Switch it to “Large icons” if needed then click Power Options.

    1. Click on the “Choose what the power button does” link on the left side.
    2. By default, the Shutdown settings options are greyed out. Click on “Change settings that are currently unavailable” to unlock the greyed out options.
    3. Uncheck the “Turn on fast startup option” to enable/disable the fast startup feature.
    4. Click Save
    5. Do a restart.

    Option 2: Run the Windows Troubleshooter

    1. Open Start > Settings > Update & security > Troubleshoot
    2. Scroll down
    3. Click Hardware and Devices
    4. Click Run the Troubleshooter
    5. Restart afterward and observe for changes.

    Option 3: Perform a Clean boot.

    Putting your system in Clean Boot state helps in identifying if any third-party applications or startup items are causing the issue. Kindly follow the steps from the Microsoft article mentioned below to perform a Clean Boot.

    How to perform a clean boot in Windows

    http://support.microsoft.com/kb/929135/en-us

    Once booted, check and observe.

    IMPORTANT NOTE: On the article, refer to section "Reset the computer to start normally after clean boot troubleshooting" to reset the computer to start again as normal after troubleshooting.

    Option 4: Run the SFC Scan

    1. In the Search dialog box on Windows 10, type “cmd” and press the Enter key

    2.Right-click on Command Prompt program from the search results

    1. Click on “Run as Administrator” from the drop-down menu
    2. Run the SFC Scan
    3. Type the following command in the Command Prompt window

    sfc /scannow

    1. Press the Enter key to execute the program
    2. It may take a few minutes to a half-hour for completing the SFC scan. After the process is finished, the SFC scan reveals corrupted files and informs you about the repairs.
    3. Close the Command Prompt window and restart your computer to put the repairs into effect.

    Option 5: Run DISM

    1. Open the Command Prompt as Administrator.
    2. In the command line, copy-paste these lines one by one and press Enter after each:

    DISM /online /Cleanup-Image / ScanHealth

    DISM /Online /Cleanup-Image /RestoreHealth

    1. Wait until the procedure ends (it might take up to 10 minutes).
    2. Restart your PC.

    Option 6: Use Performance Troubleshooter

    1. Open the Command Prompt program by right-clicking on it and selecting “Run as Administrator”
    2. Type the following command and press the Enter key

    msdt.exe /id PerformanceDiagnostic

    1. Let the command execute and finish
    2. Restart your computer later, and check if the dwm.exe file is facing errors.

    Method 5: Perform Windows Update

    Select Start > Settings > Update & Security > Windows Update , and then select Check for updates. If updates are available, install them.
