HP 8100 TOWER, i5 660, 8 GB RAM, 500 GB Sata, Windows 10, MS office, Chrome, foxit reader, imagestone viewver.

PC is restarting. Checked ram one by one, put thermal paste on processor. It is still resarting. It restarts when I open programs. I checked processes and disk usage goes 100%. after sometime it restarts. When I stop working on windows, usage goes down to 0 to 10.

I have also tried all fixes mentioned below. It is still restarting by doin all one by one, and still 100 disk usage.

Disable SuperFetch service.
Update device drivers.

Update windows 20H2
Perform a diskcheck.
Reset Virtual Memory.
Disable Antivirus Software temporarily.
Fix your StorAHCI.sys driver.


Then I removed HDD, insert one ram of 2 GB, and connect another old HDD with installed Windows 10. So PC was not resarting with this HDD, but it also goes 100% disk usage.

What do I do? Do I install fresh windows or any other fixes is there to do? I need to use the 1st 500 GB HDD.

Kindly help.I did it and resolved the issue by doing the following.[/B]

Go to Device Manager > Display Adapters > "Properties" of the Device > Select "Uninstall Device" from "Driver" Tab

Check this "Delete the driver software from this device", press OK and RESTART the PC.

Afer restarting it automatically detects the driver and worked fine. As well as disk usage decreased to one percent.


Thank you everyone.

PS: If someone try this above procedure and does not detect driver automatically then make sure you have backed up or downloaded your display device driver from the authorised RESOURCES.
