Windows 10: Windows 10 behaving sluggish if at all after an hour

Ever since either Sep. 29th or 30th, my laptop's been sluggish and sometimes entirely unresponsive.

I can get it to somewhat behave for about an hour by restarting, but sometimes it gets so bad I can't restart normally and must manually power off the laptop.

All I'm usually running in the foreground is Chrome, but Chrome/File Explorer/other applications are often going unresponsive, attempting to open the Start Menu/Task Manager/other Windows features either take several minutes or don't happen at all. In addition, pages on Chrome are taking near-dial up time to load, with Chrome claiming "Waiting on cache".

I have tried:
CCleaner to clean up excess files and clear basic Registry issues
Malware Bytes (came up with nothing)
Windows Memory Diagnostic (I can't seem to find the log files in event viewer besides one saying the test was run).
sfc/scannow (came up with nothing)
Kaspersky virus scan (claimed it would take 3 days, so only got 1/4 done with the scan since my comp was slow enough without the scan)
Disk Defrag (Only got to pass 7 after 8 hours).

That's everything I could think to try, and I'm between jobs so getting a professional isn't an option atm.

Laptop specs:

Samsung Series 7 Chronos (NP700Z5AH)
Windows 10
Intel Core i7, 8Gb Ram 1Tb HDD
Intel HD 4000/Nvidia GeForce GT 640M

Any help is greatly appreciated, I need the laptop to continue job hunting.

Garmin Connect won't download to Lumia 950

Well it's about 8 hours and three soft resets later and now it allows me to install the app. Guess my Windows Phone was feeling fussy or sluggish or obstinate earlier today. All good now (after wasting time on the phone with B2X, their subcontracted mobile
tech support, and also with Microsoft's tech support).

Extra Note:

Disk Usage is shown as 100%, but I'm hoping there's a free method to fix this rather than replacing my HDD.

I also cannot get into the bottom of this thing without breaking it (it's one of those​ laptops), so an HDD replacement may as well mean buying a new laptop.

 

If the disk usage is shown at 100% this probably means you have a virus. To fix this there are two options get an antivirus (Avast, Avira etc) or reset your PC. To reset the PC go to Settings>Update & Security>Recovery. Under Reset This PC on the recovery page there is a 'Get Started' button. Click on it and choose Remove Everything. Then choose the top option. Make sure to backup your files (Don't backup any file that is from an app since it might be the virus) I hope this helps.

 

Have you tried to restart it ? Open task manager and than resource monitor. See what programs that use most of your HDD first. Are they (activity that use most of your HDD) from windows or not.

 

I have a similar problem on desktop pc. Still investigating..

 

Is it caused by system activity (such as "system" or "host process") ?

 

Not sure, I see high disk usage with page file. PC does have 4GB Ram.

 

Tried virus scan, as stated the scan had an estimated completion of 3 days so I quit. Could try again, I suppose.

A back-up would take awhile as well, but may be more worth it

 

I recommend for you to reset the PC
