No Signal Input

Aug 29, 2018
So my computer spontaneously started to turn itself off at boot up. For example, I would hit the power button and then it would start and almost immediately turn itself off and then get stuck in an endless cycle of trying to turn on. I did some maintenance and managed to fix this problem by re-adjusting the RAM sticks. Now, however, I can’t get my HDMI to output a signal. I can’t even use the USB ports to say charge a phone let alone connect a keyboard or mouse. I tried the HDMI on both the GPU and the on-board graphics card with the motherboard, both of which give me nothing on the Monitor, any possible ideas as to what happened or what I can try?
