Inspiron 2020 Won't Factory Reset Windows 10 Please HELP

[MNG_Guy]

I have a desktop Inspiron 2020 Dell and I have a problem with opening up certain programs like art programs etc. I also can't open up certain setting options within the system. I'm an admin of my pc but I still can't access even normal programs. I tried to factory reset my pc deleting everything and re-install but that didn't work because it says "There was a problem resetting your pc, no changes were made." I've tried downloading virus deleting software but I can't find anything. What else should I try out to reset my pc?

If reset refuses to work, do a fresh install

download the Windows 10 media creation tool and use it to make a win 10 installer on USB

change boot order in BIOS so USB is first, hdd second
boot from installer
follow this guide: http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

when you reach the screen asking for licence, click "I don't have a key" and win 10 will continue to install and reactivate once finished

On the screen where you choose where to install win 10, if it gives you an error about GPT drives, delete all the partitions on the hdd and press next. If it still gives error, cancel out of the installer and restart PC and start installer again, it will accept next on that screen this time (some PC just need a restart here)
