Last summer I upgraded my mother board and CPU in my PC. Then in October I got a new GPU. I installed everything and everything was fine. About a month and a half ago, I went to turn on my pc and my monitor said "no signal from DisplayPort." Eventually after unplugging and plugging power to both my pc and monitor, I got it working again and thought nothing of it. Since then, this same issue has been exponentially reoccurring. I thought whatever I can fix it no big deal. Well today I went to turn on my pc and the same thing happened, however I can not get it to work this time. I've tried unplugging and replugging in all of the cables. Ive tried different display ports. I have tried using an HDMI instead and none of that worked. Then I took out my GPU and tried to run my computer through the motherboard alone, connecting via HDMI. I turn in on and it worked. Then I tried my old GPU and that did not work either. Once again I tried multiple ports on the GPU and multiple cables including the HDMI that works with the motherboard and I got nothing to display again. I tried a different PCIE slots as well and still nothing. I am wondering if this could be a power supply issue as I saw something online saying it is possible. I have my watt total on PC Part picker and it is about 150 watts less than what my power supply is good for. I think I narrowed it down to either power supply or motherboard but everything else works on my motherboard so I am not sure.
Any suggestions?
