Hi, I recently bought a custom built PC from CYBERPOWER’s website and on the first day, I was using it for a good 6 hours and all of a sudden it turned off. I tried turning it back on but to no avail, it wouldn’t turn on. When I turn on the power switch, a light on my graphic’s card turns on but when I go to press the power button on the front, nothing happens. I have an 800 watt 80 plus PSU. Could this be a power supply issue or a problem with the power button itself?
