Major Problem

The other day I was playing a game, game froze up (early access game figured it was no big deal) and realized I couldnt alt tab out or ctrl+alt+del out so I held the power button down til my computer shutdown, then I turned it back on. Its an Alienware 14 with Windows 10, and when it turns on itll sit on an Alienware loading screen normally for about 30 seconds maybe a minute, welp this time it sat for about 5. Then when it came up to the Windows 10 sign in, I couldnt click on the password bar or anything for about another 5 minutes before allowing me to type my password. Then it welcomed me and went to a dark screen (like normal) and instead of loading upvmy desktop right away, it stayed on the dark screen until popping up an error "RuntimeBroker.exe - Application Error" and it says this "The instruction at 0x00007FFB0D64C2B3 referenced memory at 0x00007FFB09DD8EB8. The required data was not placed into memory because of an I/O error status of 0xc000009c.
Click on OK to terminate program" these messages stack if I let the pc sit like this, and cant do anything with it. Please help.
