BSOD When Normal Web browsing or gaming, BCCode 101

Okay, so I decided to clean out my PC from dust and what not only to come across a problem. (I reapplied thermal paste to the CPU as well.) However to make things more complicated, before I cleaned it all out, I had trouble with an update. On June 14 late night I shut down my PC to be met with an update. Thinking nothing of it i let it run its course. A full 12 hours later, the update was NOT complete. It was on 4 out of 5. So I did what anyone would do and shut it off. Reboot, and tried the download again, this time it started at 1 out of 2 and completed. So, where did everything go wrong? This is the message I get as follows:



Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033

Additional information about the problem:

Any help would be appreciated. Tl;dr: What does this mean??
