So today I cleaned out my desktop with compressed air. A few times I picked up the tower and shook the dust out. As I put it back together and plug everything back in; it wont turn on. I look back inside and notice one of the connectors running from the the power supply isn't connected to something but I don't know what. I can't find anything to connect it to. My SSDs are plugged, my motherboard is plugged in. Any ideas?
