Minecraft launcher not working?

I just downloaded the minecraft launcher off of mineshafter, and I have verified java to work on internet explorer but not chrome. I also tried using jarfix and that has not worked.

How to ride horses in Minecraft Creative?

Yesterday I just got Minecraft computer version so I was so excited… I went on Creative first because I didn't want to be killed on survival right away. I saw a horse spawn egg in my inventory and I was like, oh yay, lets ride a horse! So then I spawned a horse and I had some apples and a lead(minecraft lasso) in my inventory. With the apple, I right clicked it to try and tame it but I hurt it instead, so I tried again and just hurt it again. I tried right clicking it with a lead but I hurt it again. Then I finally tried a saddle but THAT didn't work?

What am I doing wrong? Please help me, is it the fact that I'm on creative mode?

Almost all games on laptop are pixelated?

So, almost all of my games are pixelated and it's been like that for some time. I don't think the temperature, checked on HWMonitor, and the only games that are not pixelated are The Sims 2&3 and Minecraft.
I have an Acer Aspire 5755G
Windows 7 Ultimate,64-bit(Service Pack 1)
DirectX runtime version: 11.0
Processor Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz 2.20 GHz
Installed Memory(RAM): 8,00 GB (7,85 usable)
Graphics Card Information:
GeForce GT 540M
Driver Version:285.90

And I had owned it for like 2 years or so. And a long time ago I kind of dropped it on the ground…
But after I dropped it, the games still worked and after a long time they became pixelated.
And I wanted to take a screensho, but I can't for some reason.

Will a PC refresh delete Minecraft?

I'm talking about a PC refresh (not factory reset), so it says it will keep files and stuff. So is Minecraft treated as a file or app? What about the saved worlds in Minecraft, are those files or part of the app? I guess I don't care if it deletes Minecraft, if I can still download it again and keep my the old worlds. BUt I do care if it deletes Minecraft along with the worlds.

P.S. I don't play or care that much for Minecraft. My brother doesn't want me to refresh the PC because he is afraid it will delete Minecraft and/or the worlds.
