I know this isn't a laptop, but yesterday I was upgrading my hard drive to an SSD. After I cloned the current hard drive onto the SSD, I turned the desktop off and now it won't turn on again. Both hard drives work in other computers, but this one will not power on. I have done all the trouble shooting that I know of, like changing plugs, holding down the power button to discharge power, etc. Any advice on how I could get this machine up and running again would be great.
