I just bought one yesterday, and today when i sat down on it... i opened up a folder and my screen flashed a bright white and returned to normal...then i opened up another screen then it did it again only this time my screen went black, with the on off button flashing, and it wouldn't respond. I unpluged it and tryed again. and what do u know again? has anybody expienced this? any suggestions? what could it be from?
