I came back to my dorm after a weekend to no video output when I powered it on. I ensured it was not the HDMI cables or HDMI switch currently in use. I even tested the DP connections to my roommate's monitor and there was still no video output. My motherboard has two PCIe 16x slots so I tried both and one (of the very many) boots I finally got video output and it loaded into windows (it was in the low res like when you boot a new system with no GPU driver), I logged in and when I got to the desktop all power to my USB devices was cut off, my keyboard nor my mouse was working (I tested every USB port). Therefore I shut it down and then was unable to get video again after that, continuing to test both PCIe slots. I, unfortunately, do not have anything with me to aid in my diagnosis. At home, I have an old Quadro NVS 295 I can throw in to test if it is the GPU along with some other tools to narrow down what it could be. I also tested with another drive with Windows 10 installed that was previously in this pc and there was no video output. Due to this I assume it was not even posting although it was not boot looping, it was just booting up and staying up with no video output.
At this point, I am led to believe that it is the Motherboard. It is a little over 3 years old and was refurbished when I purchased it. I am just looking for input if my diagnosis is correct or if anyone has any other guesses/ suggestions.
