The computer in question relatively new, probably <2 years. It was already running a little slow (as all windows 10 seem to, in my experience.) however just a week ago, it started operating so slowly I literally cannot log on for at least 10 minutes, the screen is black following a successful password entry. Once the desktop finally appears, only the background is visible, for another 5 minutes then the icons appear, then after another 5 minutes or so the dock appears. after it's been loading for around 20 minutes, forget trying to open anything, it won't even open the "File Explorer" without locking up for around 2 minutes. and after it finally responds, it takes about 4 minutes for the actual windows to appear.
However, upon booting into Safe Mode (with networking) then after logging on (which is reasonably quick) the computer responds on demand, with maybe a 1-2 second delay, and that's it. I've run a Norton Virus scan (In safe mode, that is), the results were 3 low risk Adware. (I've attached the results from the scan) but to no avail, it stills runs just as slowly.
I'm currently running a Memory Diagnostic (at 94% now, with "no problems yet") However I doubt "Memory" is the issue, because, correct me if I'm wrong (probably am), if it was a memory issue it would happen regardless of which "mode" I boot into.
I've even tried "Resetting" the computer (re-installs the Operating System while keeping personal files.) and when it was at about 35% it said there was a problem resetting the computer, and could not continue.
I'm almost at my wits end, aside from doing a Factory Reset.
Any possible resolutions are greatly appreciated.
