Main Reciever freezing

The main receiver is the only one out of my 5 receivers that keeps freezing up And lags to respond to the remote. I have tried resetting the receiver in two separate ways. I did the signal testing and all the scores on each individual transponder come out in the high 90s and signal strength is good. Everything else works in regards to Apple TV, Roku, Netflix, you tube and so on…….so what’s the problem?  Could it be that I should change out my hdmi cord with a new one or should I try switching hdmi ports with Roku or apple or should I just call and get the updated genie since I am eligible and have the protection coverage with my DIRECTV account. For instance, as I’m typing this, it just froze and then went to a screen that said this No signal. please check the input connection And now restarting itself. It says a problem has been detected in the storage device system will now scan disk to attempt to fix it. This happened the other day as well, and then nothing happened. It’s at 87% standing desk. I’m waiting to get the results of what it’s gonna say. It’s 100% now and scanning again still the same message that a problem has been detected. Once again, you got to 100 and jump back to 69% and started scanning disc again
