Yoga 2 Pro: Freezing, BSODs, and restarting

Question

I got my Yoga 2 Pro in March, and I've loved it. About a month or a month and a half ago(maybe), it started having random glitches.
At first, I'd notice it when using the Netflix app. When waking the computer up from sleep when Netflix was open, it would just bluescreen and come back up and act normal. Then, it happened occasionally during shows I watched.
Then, I started having it happen more often, almost never with the same bluescreen error message. I would be browsing the web with the only program open being Firefox, and suddenly Firefox would close, saying it had something go wrong. Shortly after, I would get a BSOD.  I can't do anything to recreate or predict when something like this will happen next.
I recently updated BIOS, thinking that it could help.  I went about a week with no problems.  Out of nowhere, today, I got a BSOD when I was trying to log in after starting it up. Later, I had it restart suddenly, with no warning or bluescreen whatsoever.  Then, I had the screen freeze completely.  I couldn't use the mouse, keyboard or touchscreen. I tried ctrl+alt+delete and Ctrl+shift+esc. I did a hard restart, and it's been fine since. I have googled, looked at discussion boards, and gone through with the Lenovo Solutions Center thing to try to identify a problem.  It can't find anything, but I know there is a problem or it wouldn't bluescreen.
Please help! I may just need a new unit. :/
