    Windows 10 running slow after power outage


    So a couple weeks ago there was a power outage in my town and it screwed up my computer in a weird way. I don't have a surge protector or a ups (but I should get one). When the computer rebooted for the first time after the power outage it took about 10-20 minutes to start up fully and once it was fully up and running every program I started was running very slowly and most of the time wouldn't respond. I've already done a full computer reset and I also reinstalled Windows 10 but it is still an issue. I hope it isn't a hardware issue but if it is I'd like to know what piece of hardware it is and the steps I should do to fix/replace it.

    Chance is your HD was corrupted or even damaged due to power outage. Open Admin command prompt:
    1. Run: chkdsk /r C:
    2. then Run: dism /online /cleanup-image /restorehealth&sfc /scannow&pause


    NOTE: You can copy and paste the above to the command line then run.

    I ran chkdsk /r C: and it returned, "Chkdsk cannot run because the volume is in use by another
    process. Would you like to schedule this volume to be
    checked the next time the system restarts? (Y/N)"

    Yes, C Drive is your Windows OS so chkdsk needs to run offline. Answer yes then restart your PC, it will run chkdsk. Note that It will take a while to run and sometimes seems stalling, just let it finish chkdsk.

    I ran chkdsk after the restart but then I ran "Run: dism /online /cleanup-image /restorehealth&sfc /scannow&pause"
    and it got to 40% and returned:

    The source files could not be found.
    Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source.

    The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

    Beginning system scan. This process will take some time.

    Beginning verification phase of system scan.
    Verification 0% complete.
