Laptop screen all symbols, can not get into account?

I've had this Dell Inspiron 15 for all of about 3 hours, and when I'm on the internet, it randomly shuts off, turns back on, and displays this:

This computer has Windows 8 and when I type in my password in the box I suspect is the login screen, it just comes up with more symbols.

TL;DR: Can't get into computer. Computer is covered in symbols and gibberish. HELP. Is there a way to factory reset this computer without actually being able to get in? Or should I just send it back?
