Hey guys, the title says most of it but I'll explain the situation. I am trying to turn on my computer but it won't power on. None of the fans spin, and the power supply doesn't work when I hit the power button. However, I tested the power supply and it works fine, so I don't think that's where the problem is. The motherboard light is also clearly lit up, meaning power it getting to it. So it seems that its just the power button that doesn't work, and I've checked all of the headings on the motherboard and made sure the connections are in the proper positions, but I can't get it to work. The system worked fine the other day, and I didn't move the headings. The only change I made to the system was adding a r9 290x in place of a GTX 770, and I placed a cap on the "chassis intrusion" pins. That's it. Any ideas? Thanks.
