Keyboard and beep noises on a Laptop?

My little cousin while i was gone played with my keyboard. It was working before i left. The keys not working are g h ' (up button) Esc. When i first started up my laptop it made beeping sounds like about 50 of them. When i first went on google on my browser it was spamming ''''''''''''''''''''''''''''''' it never stops it did it everytime my laptop goes on search bar or anywhere you can type. I'm using Lenovo g570. I'm able to type the letters by on-screen keyboard.

Added (1). to be a little more accurate it makes about 30 beep noises.

Does this look like a good laptop?

http://www.bestbuy.com/...9091398274

It has Windows 8.1, Intel 4th generation i5 processor, 4gb RAM, 500gb hard drive (apparently it's a hybrid hard drive not sure if that makes it better or not), 1920 x 1080 display.

I think the screen size is perfect, and I like the ability of having the 2-in-one style, but do you think that it's very useful/worth the price? With a discount I have i'd be able to get it for around $700… Does that sound like a good price for this laptop? I'm looking for it to be portable and good to take to college for writing notes, papers, streaming movies and music, etc (not a design major where i'd be using Photoshop all the time and i'm not a heavy gamer either). The only thing is that it only has 2 USB ports but I can always get a usb hub or something for that. What do you think?

Is it possible to upgrade the CPU of a Lenovo G585 Laptop?

I'm no computer expert but I do know that my computer is pretty slow and laggy due to low CPU. I recently upgraded my RAM from 2gb to 8gb, but performance is still pretty slow because of the CPU. Is there any fix for this? Can the CPU be replaced? If so what would work with this laptop, and who could I go to to get it installed?
