i i just built my first pc and when i tried turning it on it failed. so i started panicking, thinking of a solution to the problem. then i remembered that cursed 20 + 4 cable that just wouldnt stay no matter what i did. so i opened it up (the side panel) held the 20 + 4 cable into the motherboard, turned it on, and it worked, but as soon as i let go of it the system turns off. electrical tape? PLEASE HELP! sorry if this belongs in motherboards or somewhere else.
