Recently when my computer is left on it seems to lock me out of everything. I am unable to open any new programs but the previously opened programs (foobar, firefox, game i'm playing) work pretty much the same.
I can open task manager but whenever I attempt to end a process or program it freezes then after a minute or two it gives me some sort of error. (Unable to end process access denied something like that)
It only happens after the computer being on for 5-6 hours so a quick reboot fixes it but I'd like to know what exactly is going on.
I thought maybe a virus but it doesn't really sound like one to me but I really haven't had many virus issues in the past.
