I had a motherboard die on me that I replaced. I purchased an open box motherboard from newegg.com. Everything seemed fine then one morning the computer starts up but no video I asked for opinions and the most people said the video died. Okay I purchase a new one-computer shows video now. Then two days later when I boot my computer it does the same thing and boots into windows but no video. Weird thing is I left the computer on while I went downstairs for about ten minutes I come back and restart then the picture shows up. I’ve tested this a few times and it’s consistent when I use the computer for a while shut down the video won’t come on unless I leave the computer on for a while then restart. I have no idea what’s wrong now since I hooked my monitor up to my laptop and it comes on fine.
