Chatt,
O.k. doing a refresh would be a last resort option is most cases were corrupt files can not be fixed with System File Checker or DISM command i gave you. Not sure if system restore is working properly yet, i would test that also, it is good to use this as it can help you revert back to earlier time when PC did not have the problem rather then doing a refresh because with this you will loose all added software, drivers and updates you already had on system .
Be careful on certain software you choose to put on and try make sure have a restore point before you do in case of issues. Do research of software well.
After you put all windows updates back on i would suggest you doing a chkdsk on main C: Drive . At Command Prompt (Admin) Copy and Paste chkdsk c: /f /r
This will take an hour or more so do it when you are not using PC for awhile. This will check and fix files on the drive, check for any bad sectors on drive and if health is good, may possibly been causing you issues.
You can post result here for us to look at it, this way
1. Press the Windows + R keys to open the Run dialog, type powershell.exe, and press Enter.
2. In PowerShell, copy and paste the command below, and press Enter.
get-winevent -FilterHashTable @{logname="Application"; id="1001"}| ?{$_.providername –match "wininit"} | fl timecreated, message | out-file Desktop\CHKDSKResults.txt
3. You will now have a CHKDSKResults.txt file created on your desktop that is the log file of your chkdsk scan results from Event Viewer.
Then can run DISM again at admin command prompt dism /online /cleanup-image /restorehealth
Also SFC same admin command prompt sfc /scannow
As far as a virus, adware or spyware i am not certain if there was any, why i originally asked to post in Malware removal here. Let's see how it runs for you in coming days, post back if need help.
Just go through same order of doing Disk Cleanup, removing unwanted Startup Programs, defragging and windows updates and hardware drivers updates for system which now will be lost in doing a refresh.
