The system just keeps rebooting if I try to forward video on YouTube and other streaming apps.

This time it stayed at the boot animation for long time, I had to unplug and put it back again to fix it.

Is it a common box issue? I've plugged in a 32 gig pen drive for extra storage and a Bluetooth keyboard receiver to the back using a USB extension, can this cause issues?

P.S. I'm on latest update it received stable and I already reset it atleast 5 times after to fix some slow down issues already.
