So let me tell you a story.A couple of days ago i installed a new power supply and graphics card in my computer, but as soon as i started the system i kept hearing this high pitched sound coming from my system and it would start booting but a couple of seconds later the system completely turns it self off.I checked all the wiring it was fine and i unistalled the components and windows booted up fine.I would like to know how to fix this problem and whats wrong.
