Hi, my NV ran fine for a while, about 20hrs, then it suddenly started to crash to desktop every few hours and i would log back into it fine and continue, however after about 73hrs gameplay and downloading the DLC's Old World Blue's, Gun Runners Arsenal and Honest Hearts the crashes became progressively more constant and are now at the stage where the game crashes every time i fast travel or when i get about 3 mins into the game making it unplayable.

My comp specs are fine and I had run NV on the highest graphics it could go with no lag, even now there is no lag or loading glitches, it just crashes constantly. Ive looked up a few guides but they dont help im not using any mods. Anyone got any suggestions?

You've patched the game the the latest edition right?

Yes, its completely up to date.
