All the posts confirming the same thing, don't delay and don't use the computer until it gets fixed. It can cause any unwanted mishaps. Your system is well under warranty. Return it and get it fixed as soon as possible. For sure, there is nothing to do with the software of the PC......................
If you really wanted to you could open it up do a visual (power off) inspection if you don't notice anything do a visual (power on) check if you cant see anything return it. Or just take it back right away.
You can also see video tutorials from Youtube regarding that problem. You can give it a try.
Did anyone mention you should take it back ? ?
Turn it back in! Or your warranty might get screwd! Might already be though since you opened it.
