Windows 8.1 Laptop Lagging?

I have recently wiped the hard drive. I had to put in another hard drive. I will use minecraft as an example, but I used to be able to run even small modpacks with good fps (around the 30's). However, now I have even more space on the hard drive and I can't even play the basic game with terrible graphics and everything on low. (I'm only getting 15 fps at the most) Needless to say it is impossble to run any modpacks as the basic game is not playing as well as it should be. The specs aren't brilliant but should run minecraft WELL. I have updated everything and even turned off background programs, I run with battery set to performance and the computer set to performance. I have also disabled any 'graphical' options like shadows on windows and things like that.

Added (1). I have also allocated minecraft more RAM, I think about 5.

Added (2). I think I should say that I have downloaded some VERY nice looking apps from the windows store, and they run perfect. The graphics are comparable to console and it runs smoothly. Yet it can't play minecraft with normal settings?

Hilarious Gamer YouTubers?

So, I'm looking for hilarious gamer youtubers. Youtubers similar to DashieGames, Tobuscus, Smosh Games, RunJDRun, TheGamingLemon, and EatMyDiction1. I really love watching different gameplays/playthroughs that are hilarious. I also enjoy watching LCPDFR youtubers such as Bay Area Buggs, and Jeff Favignano.

Any suggestions?

P.S. I like funny minecraft youtubers as well.

I need a creative minecraft username? - 1

Please READ THIS BEFORE ANSWERING.
Things that can help you think of one:
1. I'm a girl
2. I like fawns, foxes and pikas (not pikachu) i like fawns the most
3. I want it to be cute, short and sweet (not too girly)
4. I would prefer a username without numbers (if you HAD to incorporate a number, then my fav number is 8)
5. I would LOVE it if you could come up with one incorporating the animal 'fawn' in it, as i love fawns and i would like my username to have 'fawn' in it.
Other things i like:
Nature, watermelon, lavender, lilac, daises.
Please try and suggest more than one. Thanks.
Btw; i thought of 'itsfawn' but i think its a bit too plain, so many you can jazz it up a bit?
