So randomly my computer shutdown, went to start it and it wouldn't start. i noticed that the gpu led would flicker and computer would fail to start. I have moved the GPU to every available PCI slot, i have changed my powersupply. If i only have the 6 pin plugged in, computer will boot. if i plug in the 8 pin it will just flicked and fail to start. i have scoured everywhere to figure out why. my computer is fairly old and is time for a new upgrade but i dont have money for it right now.
