My Nextbook Ares 8A tablet is fully charged, but turns off after less than five minutes of playing a game. I cannot feel any warmth coming from the device, so it can't be caused by overheating. PLEASE HELP!

Could be a bad battery. They give a false fully charged message when they are going bad because they actually hold and access less and less of the charging capacity. You may well need to replace it.
