Strange dayz mod problem with display driver crashing. HELP PLEASE

[Gartho]

Ok, so ive recently gotten back into Arma 2 dayz again. It has been working perfectly for the last 2 days until today. I use Dayz Commander to join dayz servers and today I tried to join as normal, all went well until I spawned in to the game which was when I started to experience slight graphical errors across my screen (black and white lines) then a black screen but the sound was still in the background. Immediately I knew my display driver had crashed and honeslty this does happen sometimes to me but after the second launch it is usually running fine. Although this time it wasn't id make it to the same part each time and then just crash. Sometimes I would even have to restart my computer because the display driver didn't recover fully. Im going to include my RPT log and hope that someone can help me. ALSO the main menu would even crash. If i launch without dayz commander and sit on the main menu for 10 seconds it would result in another display driver crash.

Ive tried:

Verifying integrity of both Arma 2 OA and Arma 2 base game.
Launching in windowed.
Restarting PC
Resetting graphics settings (it was difficult to do this as the game would crash very quickly so I had to be fast)

RPT Logs: (I have included a picture of my logs too.)
