    Lately, I have been getting computer crashes where my monitor loses a signal from the computer, the gpu fan goes to 100%, and my computer becomes unresponsive (shutdown keyboard command doesn't work). This happens more and more often, to the point where it crashes before the computer can even post. However, when I open up the computer and jiggle around the connections, sometimes pulling out cords and re-plugging them in, this seems to completely fix the problem, until a couple days pass and the process repeats. I am certain I have a loose connection somewhere, but I'm not sure where. Should I replace the power supply or the motherboard? Or could something else be causing the issue? Thank you for any help!

    I would start with swapping in a known good pw supply. While the case is open, get a bright light and give the mb a VERY close inspection. Look for any capacitors that look like the pics below.

    go with trial and error, dont go buying expensive parts if it could possibly not be the problem, what it seems to me is that your having cable problems, first i would clean all the dust out and look at the connector ends, look over the cables and see if you have and cuts. if it comes down to it pull your motherboard out and hook it up while it lays on a piece of cardboard and see how it runs, your could just have a case grounding problem that is about 85 % of faluries not related to viruses or worms
