Black screen after login, Safe mode OK

My laptop seems to hang after the login screen, the screen either goes completely black or sometimes shows the desktop picture and an empty taskbar, but I am unable to do anything such as task manager. Leaving the system running for 10-15 minutes after trying ctrl-alt-del will bring up some error message, but I forget what it said, I'll try to get it again.

I can get into Safe Mode just fine, and ran the SF Diagnostic Tool from there, I have attached the files it created as requested. The laptop hung on me on shutdown before this issue started and after waiting for 30 minutes for it to try to shut down normally it wasn't responding so I had to power it down. I'm thinking that might've fudged something up but I'm unsure if there were any windows updates queued at the time or not.

I'm really unsure what to do at this point, there aren't any System Restore points, I didn't remember turning it off but I must have at some point.

I finally got the error message to pop back up, been waiting this entire time for it to just appear. "Failure to display security and shut down options." "The logon process was unable to display security and logon options when CTRL + ALT + DELETE was pressed. If the operating system does not respon, press ESC or restart the computer by using the power switch."

I've ran chkdsk /f on reboot 2 times already, it found 1 error and fixed it but didn't change anything. Attempting SFC now twice it gets to Verification 9% complete and then after about 5 minutes it eventually says "Windows Resource Protection could not perform the requested operation."

I'm not sure if there was an update waiting or not, the problem first started yesterday after I had to power down when my system hung on the shutting down screen for 30 minutes when closing background programs but the list was empty.

I'll attempt a clean boot now and see if it works.

Clean boot is booting fine, albeit a bit slower than my old normal boot, and the windows boot sound seems to be delayed a minute after boot but I don't know if that even means anything. It does seem to stay on the Welcome screen longer than it used to however. 3 clean boots all manage to get to desktop just fine though.
