I have an HP Notebook, which I've had for about 18 months, running Windows 10. The entire time I've had it, once it starts up, the Disk Use will go straight to 100%, with zero programs open. Then it just stays there. Sometimes, after being on for a few hours, the Disk Use will go down to something reasonable. But it never lasts for long. I've looked around for various solutions over the last year, but nothing has worked. And truthfully, I don't have a good recollection of what I've even done at this point. The computer is always making noise and always running slow, and it's very frustrating. Any help would be appreciated.
