Hello i'm new to site, I just got a system build and when i shut down my computer my motherboard stays on (lights on the mother board are on when the computer is off) as well as my speakers staying on. I have a 600 watt Zaleman PS with a power switch and have to turn off the power switch after every shutdown to make the mother board and speakers turn off. My question is should the mother board shut off when I turn off the computer? Do i have to turn my power switch off after every use?! Is it OK to leave the power supply on when I'm not using my computer? Thanks! ^^
