Crashing :s

I have recently started a new game on Friday and experienced no problems at all as usual untill today. Every now and again the game will crash and make a crash dump after saving the game or continuing through the game (I.e game loading etc). I don't have a clue why this is happening all of a sudden. I know this will most likely have nothing to do with it but it wouldn't be effected by having the HDD removed and then installed again at any point, although this was done when the PC etc was shut down and powered off.
Really don't know whats going on and I will really appreciate any help given!!
Cheers M1D

**** Forgot to add, I'm running FM on the latest patch with a few data edits. Nothing that hasn't effected the game before.

first thing would do to try a re-install of FM. usually that helps.

Yeah just done that recently and it seems to be working alright atm. Hopefully for the long run!! haha
