That blue screen code is related to, according to MS, a device driver, system firmware, or an upgrading error. Since your watching video or playing games when it happens, my first bet would be that it's related to your video driver. Reinstalling or updating the video driver may fix the problem.
Are you using a video card or is it onboard video? Post your computer specs...
It could also be a ram issue. I just fixed a blue screen error a week ago on someone's Dell system with the same blue screen code. The problem was not a driver issue in this case, it was a ram issue. One of the ram modules had gone bad. Starting the computer with only one stick of ram may help. This will help isolate what ram module is the culprit, if ram is the problem. Re-seating the ram may help. If starting the computer with only one stick of ram leaves you with insufficient memory to start the OS, just download and run
MEMtest86 and run diagnostics for a couple of hours and see if it reports "errors". Burn the .iso file to Cd and boot off of it
