Games on my computer keep Blue Screening error info in thread

I have had this problem for a while now, I built my rig this summer and games I installed on here have been working just fine. But as soon as I got Left 4 dead, and a bunch of other games on steam. I've noticed a lot of game BSOD'ing (blue screen of death) on me.

These are the games i have had the problems with:
Alien swarm: wont boot, BSOD after the first loading screen
Dead Island: BSOD after selecting my character for campaign
Killing Floor: BSOD when click on LAN tab for finding games, BSOD when trying to host a game.
Left 4 dead: BSOD after loading screen before main menu
Left 4 dead 2: same as left 4 dead 1.
Operation Flash point: Dragon Rising: BSOD before game even starts.

I have tried re installing these games, and the problem still persists.
Here are my Computers Specs:
Intel Core i7-2600 CPU 3.400GHz 3.70 GHz
8GB RAM
64-bit Operating System
NVIDIA GeForce 560 2gb

Here are some of my NVIDIA control panel settings:
