I had those stability issues when i bought my minipc, i was frustrated with it, thinking to send back it to the seller. No way to make my device runs stable until i made some test to the stock power supply who comes with my stick (mk808b). I connected an ampere meter to it and found that its marked like 2A power supply but maximum that it gives was 1,2A under load, I tested some other power supplies, and saw how optimistic are some manufacturers about their power supplies. They said that can give an amount of amperes, and under hight load they works only giving the half they announce.
I bought a new quality power supply (Psvita one) that only announce 1,5A, and i found all stability problems goes away. No freezes, no reboots, it works stable like a rock. While the stock power suply can give only 1,2A with heat on it, the new one gives me 1,8A and works cool.
Feed the stick with the tv usb output is not a good idea, cause it is not designed to give so much power out, and in some case it could work, but not allways.
Not only the Amperes what the PSU can give is the problem, bad quality PSU afect with electricals noise our tv sticks.
summary: |
PLS, IF YOU HAVE STABILITY ISSUES, TRY A QUALITY POWER SUPPLY BEFORE COMPLAINS ABOUT ROM STABILITY OR DEFECTIVE DEVICES. |
And pls, all who don't have stability issues post your power supplies name, and how it works.
Mine: PSVITA power supply. http://www.amazon.com/gp/aw/d/B006JK...m_ps2?pi=SX125
Attached to it: External usb hd, wireless keyboard and mouse and ipazzport 3D fly air mouse.
Sorry about my English, and if you want to ask anything, i will try to answer it if I can.
NOTE: The psvita power supply need to be modded to connect standard usb ports in it, is very easy. Only break some plastics sheets in the usb output.

A very good explication of I said.
