I'm having the strangest issue upon starting up my computer. Basically when I push the power button to my computer the fans start spinning but there is no display on my monitor. I hear a fan turning on, ramping up speed, then turning off every ~2 seconds. After investigation I've discovered it was my GPU making the noise. So while it was in this loop I ensured all connections were secure, and that's when I found the solution. If I push on the 24 pin EATXPWR cable connected to the motherboard the computer starts and runs perfectly fine until the next restart. I should note my GPU gets power from the motherboard itself.
So I'm just posting in case anyone is having the same issue or if anyone has any idea what is causing this. I've ensured that the connection is secure to the motherboard.
