My pc keeps rebooting when I turn it on and repeats forever

[Nubr0]

My asus x551ma keeps rebooting when I turn it on. First it shows me the asus logo. Next the asus logo goes away and it is just a gray screen. Then it turns off and turns back on again and repeats. I do not have a install disk or anything like that, I tried to see if I could boot it up from the BIOS menu I saves and exited and it just went back to the loop. Right now I'm on my moms computer typing this, so please help me out. Any solutions would save me alot since I can't get a new one.[video="https://www.youtube.com/watch?v=1w2ObJx57XM&feature=youtu.be"][/video]

Have you changed any settings in the bios? I would advise running bios if so and resetting values to default. Other options could include removing your battery if possible to ensure it is fully shutdown.

I was going to take out the battery but I couldn't get the back unscrewed (the battery is INSIDE instead of outside for some reason) but I will try resetting the bios to default. EDIT: I tried that but it is still doing it. We're going to best buy today though to see if they can do anything. Thanks for your help.
