Hello, i buy new Sapphire rx480 8 GB. 3 days he works perfect. After free days screen just turn off and about 5 seconds he turn on and work about 1 min and turn off again. Some times screen show whites lines, some time windows just shut down . I try reinstall drivers, windows, connect with differents cables(HDMI, DP). Should i make a return?
