BSOD playing StarCraft 2 and watching YouTube

Hi,

I was playing Starcraft 2, and I got a Blue screen, and it said System Service Exception. But, I didn't get the information on that.

A few hours later, I was watching YouTube, and I got another BSOD.

Here's the information:

I'm a complete noob on computer stuff, so you have to speak like you're speaking to a kid, haha.
