Windows 10: PC lag -> reset - > super slow black screen

PC Specs -based off memory

Windows 10

H97 -PRO Gamer - UEFI BIOS

Intel i5-4460 - 3.2GHz
Nvidia Geforce 97032GB RAM
2TB HDD - Seagate st2000dm001
Symptoms

Initially I started noticing my PC was getting frequent lag spikes in games.

Overtime weeks? the PC itself started processing all actions slower and slower.

3 days ago, I updated it with the latest windows update. The slowness now got to a point of loading the PC up took so long I decided to do a PC reset [Keeping files, not the clean install for resale]

After Reset -
Was fine going through the new windows setup phase. The moment it logged into the Desktop booting up the taskbar etc, it became UNBELIEVABLY slow. Disk was at 100% despite the most consuming process only being 0.1-0.3ms

Thought was strange after a reset to be so slow, checked online and saw multiple posts about 100 disk problems after reset mainly reflecting the windows 10 which is strange since I did the exact same update on my other newer PC which is having problems at all

Tried -
- Device manager - no ! showed up

- Energy options - changed to high

- disabled windows search

- MSIsupported "1" to "0" - reboot and didnt work, still super slow.


Didnt do the below -

- Superfetch - Couldnt locate such a service on the PC

- No antivirus came with the PC

After the MSIsupport trick reboot - [this took almost 1 hour now]
- chkdsk - Healthy

Tried reboot again to test SAFE mode - loaded in and was also very slow, not as slow as normal mode but every command to do something would take 5-10mins

Tried -

- SFC /scannow - OK [Took 3-4 hours]

By the time this finished, the PC was COMPLETELY FINE. [Was hoping the slow SAFE mode was a sign of bad HDD so all I had to do was replace it]
I opened device manager just in case and noticed outdated drivers with !


Decided to reboot again to boot SAFE mode with network so i can update those drivers, very slow load up and slow processing again...

On my 3rd day so far still slowly trying to figure out the problem...
Any diagnosis and ideas would be appreciated

:)

 

Super super super slow running Windows 10

I have a Samsung touch screen computer. I upgraded to Windows 10 a couple of months ago. I have Norton antivirus. A couple of weeks ago my computer started to run slow. I did a "go back to a known good date" reset. worked for a while. then started to slow
down. Now it takes over an hour from turning on computer to get to google web page. It works, but is super super slow. Do you have a suggestion to try so I dont lose my saved data. I have only got on set up (F8) once on many attempts. Thank you for any help.
