Windows 10: Why is my disk running at 100%?

Task manager is showing disk usage at 100% but none of the processes are running more than .1 MB of usage on a terra-byte drive. What's going on?

Disk Usage at 100% with nothing running

My PC is running Windows 10 with the latest updates but has suddenly become unusable with disk usage staying at 100% even with nothing running and just the same processes listed in Task Manager as before the problems
started. I've tried a few suggestions found in online forums - disabling Windows Search and Superfetch, adjusting page file size, etc. but nothing has done the trick yet. I don't have any outside anti-virus software installed. I read about the potential MSI
issue but don't have IDE ATA/ATAPI Controllers listed in the Device Manager. Finally, it seems to boot up normally and will have periods where the disk usage drops and it's usable but those moments are brief and it inevitably goes back up to 100% usage.

 

Clean install, disk usage at 100%

I've seen that article. and I am in fact not running that driver. I followed the steps and it does not appear in the list.

<snip>

In the Task Manager, under Performance tab, the disk utilization reaches to 100% due to which system became lagging and unresponsive. It started freezing in few moments and this keeps happening until disk usage reduces from 100%.

Control panel > Power Options > Edit Plan Settings > Change Advanced Power Settings > Processor Power Management > Maximum Processor state.

Also, once I start Chrome 64, it uses lots of cpu and ram to do absolutely nothing.

before you decide to download and install it. Sometimes they include 3rd party programs, "unwanted" programs that are automatically installed during a standard install. So, if offered, do a "custom" install and carefully read each step. One of the steps MAY
give you an option to install, or NOT, "additional" programs. 99.9% of the time you don't want to let them be installed. For example, when you install Adobe Player you are given the option of installing 2 additional "free trial" programs: Potentially Unwanted
Programs: MacAfee Security Scan and MacAfee Safe Connect. The option to install is turned on, you have to manually turn it off. Those are PUP's. If you click "OK"/"Next" without paying attention you get the 2 "extra" programs.

As well, watch out for ads on the site. They may advertise products that include PUPs. Thoroughly research any product advertised on the site before you decide to download and install it.
