Pc stuck on black screen after windows login?

Once I sign into windows it shows a black screen with a cursor, it won’t let me open task manager after I try to click on it. Then after a few minutes it brings me to my home screen with error message . I can use edge, but when I try to uninstall something or use task manager and other things it wont load. This happen after I tried to download a rom for dolphin emulator and idk what’s going on. Please help

How do I uninstall the ROM, is it in BIOS?

2nd EDIT: You said you tried to download a "rom for dolphin emulator". Uninstall that, whatever it is.  Remove it. Also run a full virus scan and then reboot. 

Orig. What is the error message.  That may be directing you to theproblem. 

EDIT to add: Ok, first things first, uninstall the ROM.  then reboot and check all your drivers.  the Rom is somehow locking the drive and not giving you access...or at least tht's what it seems.  The only way to know for sure is to uninstall and see how things work afterward.
