HELP!

Hi so my 04 Yukon Denali just started doing this this morning. On the dash the only thing that is working is the speedometer and the rpm. Everything else is flat lined. The buttons on the two front doors aren't working either. The radio will turn on but no sound. We just went to O'Reilly and the battery, starter, and the alternator all checks out. They checked the fuses under the hood and those also check out. We are at a loss and don't know what else to do!
