last september i built my own computer and it has worked until now. Recently my computer would not turn off even when i commanded it to, so i have had to turn it off manually. today it was working until i was playing a game, fear, and the game froze. i turned off the computer manually and proceeded to turn it back one, and it wouldnt. none of the fans would spin, none of the lights or leds worked, and my router does not indicate thecomputer as connecetd as it usually does when its off. lastly, when my computer was off but working, before this happened, one green indicator light would stay on in the computer, but now it is not. i believe the issue is either the mobo or psu, but i dont know for sure, nor do i know how to test it. please help, i would be grateful!!!!
