Task manager - Can't end processes (Access Denied)

Recently I've been having problems ending processes. Whenever I try to end a certain processes I keep getting an access denied error and I have no other way of removing processes as it wont go away even if I turn off my computer. This is pretty weird considering what I'm trying to end is game processes. So now I can't play certain games as I keep getting "Program is already opened" errors when I try to play them and there's no way I can play them. Some of the games that still play even without me having to kill the task completely now have multiple copies of the process and I can't end any of them.

I've tried messing with the permissions on the files and it didn't work, I also tried messing with the admin rights and such but no luck. My account is an admin

Can anyone help me out?
