Hello. I have built a new PC (it being my first time) and installed all the hardware properly. When I booted up for the first time, No video came on my monitor and heard one long beep and three short ones, which i believe meant an issue with the ram. I tried switching the ram to a different slot and messed around with it booting up in total of about four times, disconnecting the hard drive several times but still getting the same beeps. This last time, in order to get video on my monitor I tried disconnecting my graphics card and reinstalling it, but now when I try to boot up and hit the power button nothing happens. Nothing spins no noise or anything. I don't know what I did wrong this time but this is worse than the ram issue i fear.
