There's so much to cover that let's try a few things to salvage your installed and partially broken W10.
Step 1. CHKDSK /F/X all drives.
You may have to open an elevated command prompt to do this. (Plenty of articles about this and CHKDSK so I'll pause here.
Step 2. If the problems continue, try Windows 10 built in repair feature (Refresh.)
If that fails, use the RESET. (Files may go away with reset.)

I got a massive issue with my computer, it was working fine until it blue screened today, after it happened i could no longer use steam (or any of the games via steam) and my graphics drivers wouldn't install, to make matters worse anything I downloaded would just say "this won't run on your pc"
It's come down to being the SSD i scanned it and it told me it needs repairing but every time i delete or uninstall something on my computer once it has restarted it acts like it never happened so i cannot even fix the SSD.
I tried using a windows media creation tool on my usb to put windows on my HDD instead but it wouldn't allow me as well as not letting me format my SSD to fix the issue.
Please help me I'm going insane
