Why am I scared of minecraft animals?

So. I built an animal pen on minecraft and trapped all of the animals in there, I built a platform for me to stand on for feeding them. Once, I stood on top of the platform to feed the sheep and cows, then I fell down the platform then the cows and sheep started mobbing me. I felt so scared and then started hitting the animals in my way and ran away. After that I can't upgrade my pen because whenever I enter the pen, the animals will go and disturb me. Someone help me? Like how to get rid of my fear? Btw, I also get head aches whenever I play minecraft in the car… Thanks

Why does my higher end gaming laptop run some games slower than my old lower end one?

Okay so basically, a few weeks ago i got a new laptop to be specific its an Alienware 17 2013 model, and my old laptop was an ASUS N56V. And all of the specs on my alienware are rather higher than what i had on my asus. Majority of the programs run wonderfully on this Alienware as to where on the ASUS they did not. But games like Minecraft, and the original Bioshock ran much smoother on my old one, both of the computers had the setting maxed out too. But my old one could hardly run Crysis or Farcry 3 on low settings where this new laptop can max them out. After i noticed the bioshock lag after the first boot, i went back and found my Farcry 3 was running ever so slightly lower than earlier (Average 40-50 frames, was getting 30, so still very playable). The specs on the alienware are as follows (Sorry if i forget some of the specs)

Alienware 17:
GPU: Nvidia Geforce GTX 770M
CPU: Intel Core i7 4700M (Quad core, 2.4 GHZ, Turbo boost to 3.4 GHZ)
RAM: 16 GB
1.5 TB (750 GB x 2); 80 GB (Solid State) 7200rpm

and the ASUS had:
GPU: Nvidia Geforce 635M
CPU: Intel Core i7 3630QM (I think Quadcore and forsure 2.4 GHZ)
RAM: 12GB
And a 1TB HDD (Don't remember the rpm)
So if you could give me any answers as to why its running slower it'd be greatly appreciated. I got a 2 year warranty if it sounds like a GPU or CPU issue. But at the same time i don't see how it could be if some games are running phenominally, as to where others seem to struggle just as bad or worse as my old one

Good gameplay recording software for YouTube?

So I recently decided to make a new Minecraft gaming channel. Yay!

I have the account made. (RainbowCrafterHD) The username is similar one I use for all social networks. I got it from a username generator YEARS ago.

The banner and profile picture are being made by a very talented GFX artist I know on YouTube for free. (Who only speaks German, making it quite hard to communicate. )

I ordered my new Acer Aspire V5 laptop for playing, which should arrive at my house anywhere from Wednesday-Friday of next week.

I'll get Minecraft within a few days of getting that.

SO HERES THE THING
I'm that kid that doesn't want his parents to spend a lot of money. When I want something i'm constantly finding ways to save money including selling stuff I already have. Which is what I did to get my computer.
So Minecraft and that new laptop is pretty expensive for my parents, even with the stuff I sold. So I don't want them to have to spend much more on anything else.
But I still need a gameplay recording software to post my gameplay to YouTube.

What's a cheap HD recording software that also can record sound that's going on in-game and over Skype calls? WITHOUT A WATERMARK ON IT.

Cheap as in 15-24 US dollars cheap.

Is it possible to make my hp 2000 laptop better for gaming?

I recently got an hp 2000 notebook pc for Christmas. It runs on windows 8 and is an ok laptop. But i've noticed it doesn't work well for gaming. I was wondering if its possible to make it run games better and less choppy and laggy. Such games would include minecraft and Dayz.

Added (1). Response: thanks for the news. I'm thinking of selling this laptop afteri raise the proper funds. Any suggestions on a cheap gaming laptop? (I know they are expensive, just need a starting point.)

Added (2). Oh, and just to be sure, would replacing the processor help at all?(if such a task is possible)

Added (3). Response: thanks. Any additional information or things I should know would be wonderful:3

Added (4). Additional question: i've also heard something about having my laptop focus its hard drive or some component of the sort on soley graphics and performance. This concept is kind of vauge to me, but from what people say this could help boost gaming performance. I would like to know more information on what this is and how its done.
