Flashing white screen

I assembled and everything was working perfectly. Even played bunch games. Than I connected to computer and tried some codings and now when i opened my device white screen flashes for 2 secs in every 4 sec and nothing else appears. Tried to reset but no luck. Any ideas?

How are you installing the games? Through the bin method or through Arduino IDE?
