My LG LW40 Express Laptop won't start. What can I do?

Hello! I've got a LG LW40 Express Laptop. Whenever I turn it on, a black screen apologizing for inconvenience is what I see. It says that Windows didn't start successfully because of a software or hardware change. The screen lists modes of start up: Safe Mode/Safe Mode with Networking/Safe Mode with Command Prompt/Last Good Configuration and Start Windows Normally. I've tried all modes of start up and came to nothing. At first, it seems that windows is starting but all of a sudden the screen goes black and the one with the apology and modes of start up reappears. What can I do?
