The system powers down after 5 seconds and then restarts and powers down again, but only if I do not remove the jumper. If I remove the jumper, it will start up and stay that way, but the keyboard and monitor will not work. I use the i7-3770 and 32 GB of 1600 memory. It is a brand new build. I think that it has to do with the bios, but the bios will not come up after it starts.
