When I went to turn on my computer today, my monitor gave me a "no signal" issue and then the screen turned black, but the monitor light stayed yellow. I feel like my computer not POSTing is also an issue because I can't even get into the BIOS. I also recently installed a CPU cooler, but i didn't have the correct mounting bracket so i used tape to prevent the screws for the cooler from touching the motherboard backplate. I'm not sure if this is an issue preventing my system to POST. I have included photos for your reference.
