Random Crashes No BSOD Pixalated screen

I did a fresh install of windows 7 ultimate x64 edition a few months back. For a while I was getting periodic BSODs but they have since stopped and now I just get crashes. Sometimes I can go hours or even a whole day with no crashes or issues, but now it is happening more and more often. As of right now I am running in safe mode with networking and have no issues. Up to this point I have tried reseating my graphics card and my RAM but it is making no noticeable impact. I cleaned the dust out recently. I did a stress test with my videocard using furmark.. I think it was the temp never got over 70 degrees and I had no artifacting. Other issues I have noticed have been small sound glitches and scratchy audio from time to time and sometimes as crashes get closer the audio starts to bug out more and more. I have added your debugging tools info. Any help would be appreciated, if I can narrow down the problem and find a fix that would be great. Even knowing more info would help, as I am at a loss with what to do.

An update. Not sure if its the cause, I disabled my vid card and tried to boot the pc normally to see how it would function and I got a BSoD from a driver associated with bitdefender. I uninstalled that and reinstalled the videocard as well as enabled it to see if I get the same problems as before. If so I intend to disable the vid card and see if I no longer get errors after that point. How likely would a faulty driver installed by a piece of antivirus software cause crashes like that? Or does it seem, with this in mind that it would be caused by multiple issues and that was just an underlying issue?

Okay so I got a similar crash, only this time, my browser closes down, if I try to access anything on the pc my screen goes entirely black while I have mouse control over a small area of my screen, then suddenly it freezes and a single press of the power button shuts the system off. During this time my keyboard does not appear functional, IE capslock doesn't turn on a light etc etc. It feels like, more and more its a graphics card issue but I am still not certain until I can verify how well it functions with the graphics card disabled.
