How to Troubleshoot 100% Disk Usage.
100% Disk Usage even after refreshing the Dell T5810 PC. Tried performing most troubleshooting guides available in the internet - Disabled Windows Search, Background Intelligent Serivce, Superfetch; Increased Virtual Memory etc. Also checked with Crystal Info Hard Disk which shows the performance as "Good". Updated Dell Softwares, BIOS, Drivers and Windows. The 100% with hard drive is frequent and is disrupting the work of a user. Any suggestions where I might have overlooked in troubleshooting?
If you have enough space to install and run Tree Size (Jam Software), try that. Excellent tool for graphically displaying disk usage. You can start with the trial.
Virus scan?
Try Malwarebytes https://www.malwarebytes.com/ Get the Windows version and run it. If it doesn't find anything uninstall it.
Also find the manufacturer's util for the particular hard disk you have in your system and run that over it. Both Seagate and Western Digital have utils and if you can't find them post here.
