Ok i played the game around 400 hours and i had around 3 or 4 crashes.Not a big deal for me since i like to hit F5 often and they was after many hours of gameplay.Anyway i was bored by the amber color on my HUD and PipBoy and decided to change it GREEN the good ol' Fallout 3 GREEN color After continued my game got freeze.K i said ctr+alt+del will help.Started the game again and it crashed.Stared it again and crashed again after the same amount of time.It was stupid to think about the color change but just in any case i reverse back to AMBER.And WOW no crash 3 days so far (in real time).But JUST in any case tried BLUE -------> CRASH :brokencomputer: WTH?! My OS is Windows XP 32bit and i have patched New Vegas and i don't have any DLC.
