Windows 10: What can I do if my computer suddenly start running so slow I can’t even troubleshoot it?

The computer worked fine last night, but was a little slow today. I restarted it and now it’s incredibly slow about 30 minutes to load. I can’t bring up settings even in safe mode. Lots of storage space. Very sudden drop in performance.

Computer run slow and Start menu not functioning

Hi Joe,

Thank you for posting in Community.

We are glad to provide the assistance required to help resolve your issue.

Before we proceed, I would ;like you to provide the information stated below:

• Did you make any changes to your PC prior to this issue?
• Does your computer run slow during startup?
• What is the exact issue you are facing with your Start Menu?
• Do you receive any error message with respect to the Start Menu?
• Can you provide the name of the registry tool that you are using?
• Do you have enough space in your c: drive?

For now, I suggest that you check which program is running in the background when the computer runs slow. To do so open Task Manager and check under Processes.

Also Run maintenance task which checks issues that might slow down your computer's performance, such as how many users are currently logged on to the computer and whether multiple programs are running at the same time.

• Press Windows + X on the keyboard.
• Select Control Panel.
• Select Troubleshooting.
• Click on Run maintenance task under System and Security.

As for the issue with the Start Menu, run System File Checker [SFC] scan on the computer which will replace the missing or corrupt files & check if the issue persists.

a. Right click on the Start Menu, locate and select Command Prompt (Admin).

Note: If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

b. Type the following command, and then press
ENTER:

sfc /scannow

Hope this helps

 

Why has my Laptop suddenly started running slow




















OK have done the above. Hardware seems fine, no?

PS I have set Performance Manager running. It said it is "Collecting data for 60 seconds..." however my computer is running SO slowly that after what is now 15 minutes (and counting) it has not spat out any results (!).
