My R5 ran Great!  ...until I updated the latest bios patch, then it turned into a loud noised, graphics hanging POS.  At one point it showed "cpu pump failure" in a checkbox.  trouble is....I don't have a cpu pump and there is nothing plugged into the cpu pump terminals on the MB.  Can anybody tell me what going on or how to revert to the original bios where I didn't have a problem...I wish to God I hadn't updated the bios.... Also, I ran every self-test there was and the results are that "NOTHING IS WRONG"!!???   Well something is wrong for sure...I spent 2 hrs chasing my tail on the Dell website looking for answers....there are none......
