So my computer starts turning off during an intense video game, especially when I set the graphics to high. Great, that's just the PSU dying. Pretty obvious issue/fix. One day the computer just doesn't turn on.

I buy a new PSU, and nothing. It's still dead. The MB won't even spin up any fans. So I guess the MB must be dead.

I buy a new MB, and the MB boots up, but no output. The "BOOT" and "VGA" psc leds are lit up. I do everything I'm supposed to, remove all drives, swap out RAM, go down to one stick on different slots with different sticks, unplug everything, reset the CMOS, and nothing changes.

Great. I guess the MB is dead on arrival. Or my CPU is dead. My $350, AMD 3700X that I just bought. I have no way of telling.
