Help!!! Kernel Panics

I have a MacBook Pro 2010 that is giving me major issues now. I keep getting a message box (black see-thru) that says I need to restart my laptop. It is written in about 7 different languages, and the only thing I can do is do a hard power off.

Also, my screen will turn a solid color at times. It has turned blue, black, and sometimes looks like "snow" static on a tv. Once again, the only thing I can do is to do a hard power off since I can't see what's on my screen.

What do I need to do, or is there anything I can do, besides purchasing a new MBP? Thanks.
