DVR Receiver problem - DirecTV DVR

For DVR Receiver problem, relating to DirecTV DVRs and receivers. I came home today and turned on the DVR. Started acting funny and wouldn't change channels every time. So I turned it off, unplugged it, and turned it back on. Now it says that is is in startup, the screen then goes blank, a minute or two later it powers it self off and back on. Then it starts all over again.

Ive only had direct TV for about two months. Whats up?
