100% disk usage and memory usage

Hi,

100% disk usage and memory usage can be caused by a software corruption, running application running on the background and malware or virus infection.

For us to properly isolate the issue and provide an appropriate resolution, kindly answer the questions below:

• Did the issue happen after installing the Fall Creators?
• Did you receive any error messages?
• Can you send us the screenshot of the Task Manager showing the 100% disk usage and memory usage?
• What troubleshooting steps have you done so far?

For isolation purposes, please perform a clean boot to see if the same issue will occur. Refer to this
article for more information on how to perform a clean boot
in Windows.

Looking forward to your response.

 

how to determine what's causing 100% disk usage

Considering your 2nd screenshot, assuming your Disk column is organised high to low, you have a problem with disk transfer rate- it appears to be low yet shown as 100%

There are various programs running that appear unnecessary.

Suggest you do a clean boot and compare. You should expect disk usage when idle - a few mins after boot - to be zero unless there's good reason.

Comparing your 1st and 3rd screenshots, note the max transfer rate is 10x that in the 3rd screenshot.

It's not doing an update, and not apparently a paging problem.

From that it appears you have limited disk transfer rate, and the disk activity doesn't settle to near zero.

There are several threads on the topic of limited transfer rate - here are some:
Disk usage 100% please help Solved - Page 2 - Windows 10 Forums
Slow internal hard drive tansfer speeds - Windows 10 Forums
100% Disk Usage, tried some methods found online. - Windows 10 Forums

I'd suggest looking through those first, using any ideas there, keep a list of what you try, and post back with that list if you still have problems.


Please post specs of your PC. See mine for comparison.

 

100% disk usage.

Summer has ended and my girlfriend booted her school laptop for the first time in months, only for it to be so unbearably slow that it took several minutes to log in. She handed it to me and said "fix it"... that was 3 days ago and now I am here to humbly
ask the community what is going on with this GD laptop.

It boots and task manager reports 100%CPU usage, it then lags for several seconds and displays 100%disk usage with CPU usage bouncing between 30-60%.

If you leave it alone with task manager running it will eventually quiet down to a reasonable 0-5% disk usage, but doing ANYTHING causes it to bounce right back to 100%.

I have tried EVERYTHING.

• disable superfetch.
• disable microsoft search.
• disable updates and suggestive tips.
• updated to the most current version of microsoft. (it hadn't been updated since 2018 when she bought it.)
• reconfigured AHCI PCIE.
• changed energy options.
• disabled indexing.
• reset the virtual memory.
• ran disk defragment and disabled all scheduling.
• updated all drivers.
• deleted google chrome.
• Disabled all services that weren't microsoft services and disabled all startup programs (clean boot).

Still no change in the disk usage.

Its an HP Laptop model 15-bw0xx with Windows 10 home edition version 10.0.18362

after messing with it this long im considering replacing the HDD with an SSD but I fear that it wont fix the issue.
