hey all a few months ago i had a MID7125. the tablet started having problems. Synthoms include random reboots, a buzzing sound of of nowhere, screen turning all snowy and white. Tried factory reset and everything and it still happens frequently at random times. last resort i did a warranty fix/exchange and they sent me the 7042 about 5 days ago. everything ran fine. today it started happening again. any one have any ideas what causing this?
