Local Disk (C:) Errors

Question

Hello, 

I have a question about my Local Disk (C:) and overall recent laptop performance. The past 2-3 days my laptop has slowed down a lot there is usually a big delay in the typing to screen like 3 seconds but there isn't any sound delay. Every time I open my laptop now I get a notification in my security and management that a driver error is occurring and I should restart my computer to fix the issue which I did multiple times it didn't fix the issue. I went to the recovery option to do a system restore on recent changes and my laptop is saying Local Disk (C:) one of the files is corrupted. I don't know how to quite solve this issue if anyone could give me a solution to solve this I would appreciate that a lot. I will leave a screenshot of the error in this message.

P.S - The option to Check the disk for errors doesn't work I tried multiple times.

Thanks,

Shane

Hi Shane,

Let’s try the following commands:

Click start, type “cmd” - right click and run as admin

DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each "/") - and hit enter

Wait for that to finish, and move onto the next command. Type:

sfc /scannow (note the space between "sfc" and "/") - and hit enter

Once these are done, let’s see what comes back and we’ll go from there.

Hello Charlie,

Everything went as planned and the hard drive was fixed. I continue to have some performance issues and nothing really changes. However, I went to troubleshoot my device hardware through the windows settings and it said I just had to update some drivers and restart the computer. The first time I did it with a restart it didn't work. Then I did a shutdown and turned it back on and the laptop seems to be running at where it was 3 days ago. I might be experiencing some minor issues still. One thing I did notice however is recently my AC adapter has been shorting out over the past 2-3 weeks and not working properly so I have to buy a new one since the laptop is getting the charge it needs. When I was having the performance issues my laptop was at 94% on the home screen and when the charger started to work again after I came back to the computer later the laptop was running normally again (Note- laptop was at 100% and charging after the charger started to work again.). I also pressed my F2 button upon boot to enter the settings of the laptop from the BIOS I can't recall the name at the moment and checked the power supply and it was at 81% different from the home screen most likely just an error. Anywho, I noticed my battery is exhausted and doesn't hold a long charge anymore and the AC adapter will fully break anytime soon. I will run the system diagnostics upon the boot later and inform you on what it says. I will leave you a TXT file of the logs from this morning after I woke up and the computer was done running the second command you provided me with.

Thanks, for all of the help!

Thank you for such a detailed response. It really is appreciated. Also, great work on diagnosing the battery and the power supply. Just like anything else... they have a shelf life. Replacing them will help.

Saw the TXT file, and i’m Happy it found and repaired some corrupt files. Let me know how you make out with the system diag.

You’re very welcome, and I’ll be here!

Try checking your hard disk for errors:

https://www.groovypost.com/howto/check-hard-dri...

Also try the following to see if it helps:

Open Start, type: CMD

Right click CMD

Click Run as administrator

Type in at the prompt OR Copy and Paste these one at a time : (Hit enter after each)

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /ScanHealth

Dism /Online /Cleanup-Image /RestoreHealth

Also run the System File Checker utility:

Open Start, type: CMD

Right click CMD

Click Run as administrator

At the Command Prompt, type: sfc/scannow

This will check for any integrity violations

Restart your system

I personally would backup your files then perform a new install; since this could be a sign of potential system stability issues:

Backup:

http://answers.microsoft.com/en-us/windows/wiki...

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to reactivate if necessary. or use the reset function in Windows 10.

Go to a working computer, download, create a bootable copy, then perform a clean install.

Review the following guide for instructions and details about configuring your BIOS or UEFI boot settings for DVD, CD, USB or SD Card.

Once your computer is set to boot from the DVD, you should see this option. If you are installing from a retail Windows 10 USB thumb drive, you will be asked to select either 32 or 64 bit Windows 10. Learn more here https://www.groovypost.com/howto/choose-windows...

The Windows logo will appear on screen, this might be here for a while, as long as you see the animating dots, everything should be ok.

Select your Language, Time and Keyboard method then click Next.

Click Install now

Windows 10 setup will prompt you for a product key during installation a couple times. If you originally upgraded from Windows 7 or Windows 8/8.1 click the option 'I don't have a key' and 'Do this later' . If you have a Windows 10 product key, you can proceed to enter it.

Setup will also prompt you to select the edition you have a license for - Home or Pro. Please make sure you choose the right edition. If you choose the wrong edition, your only option will be to perform a clean install again.

The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:

Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core should install Windows 10 Home 



Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro should install Windows 10 Pro

Wait while setup prepares to copy files

Accept the license terms then click Next

Click Custom: Install Windows only (advanced)

NOTE: Sometimes Windows 10 setup can become confused if it see's a thumb drive. You might get a driver missing error or something to that effect. If you do, restart setup, but this time, when you arrive at the following screen, disconnect your thumb drive then go through Custom options. When setup is ready copy files, it will prompt you to reconnect the installation source (your USB).

Select the drive then click New

NOTE: If you have multiple partitions listed, select each one (starting at the bottom), then click delete until there is only a single (one) unallocated drive displayed in the window.

Select the unallocated drive listed, click New, click Apply then OK

This will split the drive into multiple partitions, select the Primary partition then click Next.

NOTE: The System Reserved partition is where recovery files are kept for diagnostics and repairing damaged Windows 10 files; or even reinstall Windows 10.

Wait while Windows installs

When this phase of setup is complete, Windows will automatically restart then reboot into setup again.

Windows is detecting and installing your hardware. After this is complete, Windows will restart one last time.

Answer 5

I suggest you do this command first

Chkdsk c: /F

then use the commands that charlie suggested

the SFC command

Ending with the DISM

Chkdsk checks and repairs the basic disk structure

SFC fixes some system files

DISM fixes other system files.
