Hi everyone, first off I'm new to this forum and I'm coming here as a last resort to try to figure out this issue. I have a custom PC I built in May 2013 that has all the bells and whistles. One disconcerting and rather annoying thing that happens is that while I'm gaming on my Primary monitor and viewing a video (youtube or twitch TV) on the secondary, then the video starts to lag and stutter immediately when I open the game. It occurs when I play Starcraft II and Diablo III. But not XCOM: Enemy Unknown. I have not tried other games. But my impression is that the more demanding games are causing this issue (I think).
I'm not THAT experienced with computers. I mean, I built my own. I understand basic terms. I can generally figure ***** out. But I'm not an expert. Just wanted to throw that out there.
Here is the complete breakdown of my computer:

-I have performed CCleaner to clean registry.
-Tried updating to Windows 8.1 but failed at 81%. Had to perform system restore (this was a few days ago). The problem had been occuring way before this however.
-My windows updates is another issue. My computer continually checks and finds windows updates every 2 days or so. And tells me I need to install them. Some of the updates fail during installation. I have called Microsoft about this. But they want $100 to fix the issue (which is SUCH BULLSHIT because basically it's their damn windows that's broken...but my warranty was up after only 30 days??? WTF don't they have enough money? I digress...). Anyhow, I have tried Microsofts update troubleshooter/automated fixer. Didn't work. I currently have updates disabled since it will just keep on reinstalling the same updates over and over. I may just have to pay Microsoft their stupid money unless anyone here has any bright ideas. Better yet, could tell me if this issue is somehow related to the one above.
If you've read this far you are very kind. I look forward to your reply.
