I need help guys ! I were browsing through the web without putting any stress on my rig but suddenly it shuts off. So I let it sat for a few minutes and press the power on button but the fans and LEDs spin/light up for 1-2 second and turn itself off ?? If I hold down the power on button it would keep flashing on/off but won't turn on.
I tried pulling the PSU to wall socket cable out and replug but no result..
Could it be my PSU?
