Use recovery disk or warranty?

Hello,
My Toshiba Satellite P755-S5265 has been acting strangely lately. Whenever I start it up, it starts up and goes all the way up to the windows 7 screen, with the symbol that has the 4 colors. However, after that my mouse shows up and that's all that shows. It's basically a blank, black screen mouse with it.

I have a one year warranty that was included with the laptop that expires in 3 months. Should I use this warranty and go back to Office Depot for them to fix it...or should I use my recovery disk to fix it?

I'm not sure if the warranty will help as I heard bad things..any advice would help.

Thank you!

P.S. I have also tried troubleshooting the problem. I have tried holding the power button for 1 min and have tried cleaning the RAM. None of these have worked.
