I just received my PC back after shipping it, and now it won't display anything. I built the PC a while ago, so I know it worked before. I've already reseated the RAM and GPU, and I've run through all the diagnostics I can think of, but I'm still unable to find the problem. Any advice?

If there’s no integrated graphics, double-check all power connections to the GPU and motherboard. It's easy for something to get knocked loose during shipping. Also, make sure everything is seated properly and that there’s no dust or foreign material in the slots.
Have you checked if your motherboard has an integrated GPU? If it does, try connecting your monitor to that instead to see if it displays anything. Sometimes, the primary GPU may not be working even if it seems fine physically.
