I manually turned of my PC a bit ago and whenever I would turn it on it would turn on then off repeatedly until I turned it off. I switched the RAM and now it stays on but there is no display in my monitor and my keyboard and mouse aren't on, even when plugged in. I have tried different ports to. Here are my PC specs.
