Minecraft crashes at launch?

I bought Minecraft yesterday on my laptop, and whenever I try to start it, it says "The game crashed whilst initiating the game." Detailed crash says "Error: org.lwjgl. LWJGLEXCEPTION: Pixel format not accelerated."
What do I do?

Recommendations for a dell optiplex 380 upgrade?

I recently purchased a dell optiplex 380 desktop for my little brother. It has a Pentium E5800 (3.20 GHz) core, 8 GB DDR3 RAM, 1 TB HDD, Intel integrated graphics, a 255 Watt power supply, and a Windows 10 operating system. I'm trying to upgrade the graphics and power. From what I've read, the GPU needs to be single slot, and low profile (which rules out high performance graphic cards). I'm trying to upgrade the system enough for my little brother to be able to surf the internet and play lower intensity games (like minecraft and roblox). Since returning the system isn't really an option, does anyone have any recommendations? Is it even possible to be able to play those games with this system?

Help shorten Minecraft username?

My username for other games is JustAnotherDogMeme (Don't judge). Minecraft says they only accept 16 letters, mine is 18. Help! I'm trying to avoid JADM, so help please?!

Help finding a song/symphony?

Okay so I was watching a YouTube video today and a minecraft ad came on.It was a brand new ad (irrelevant) that I didn't care to watch HOW EVER the music they played in the background of this ad was A SYMPHONY. Or an orchestra song I have no clue. But it played 5 notes per beat, and those notes were flute. Or some sort of wind instrument.So the song was maybe Bach or Vivaldi or something.It was maybe baroque Ish. And it played 5 notes per beat in rapid sequence like da-da-da-da-da / da-da-da-da-da / da-da-da-da-da / da-da-da-da-da. Sounds intense, it's probably not beethovens 5th in c minor because I've tried to look it up in any way and it won't work…
