No signal when booting, all fans and LEDS work fine.

Hold power button, everything runs fine (all fans and lights), no signal. I've checked all the connections and they're fine. Dead GPU?

I heard someone say dead CPU and my heart stopped, but I'm sure it's not as my pc can just run forever fine, just has no display (from what I've seen a dead CPU means the PC turns on and then just shuts down again)

try taking the power cable out then holding the power button for 60 seconds
