Sorry tempers, I know I've been posting alot about computer problems lately. Anyway, after turning it on for a while and leaving for a bit and then coming back to the PC, I try to turn off the PC using start menu, it does not work. I try logging off or user switch, they don't work. I try CTRL+ALT+DEL, that does not work. The problem fixes once I restart the computer using hardware (the button on the PC case) instead of the software.
