My Predator g3-710 gaming desktop stopped working overnight the other day. Attempt to turn on and there was no power - the power supply, which had been quite audible before, makes no sign of starting up. I checked the power supply by disconnecting it and then jumping it from ground / on and it started up when I plugged it in. The on switch appears to be working when I check it with a multimeter and press the button. I'm gathering that this is thus a motherboard issue. I'had hoped that the PC, purchased only a few years ago (but now out of warranty) could last a bit longer. Curious if there is anything else I should check or what my next steps might be?
