Mahjers, thanks for the tips, sounds like a good idea but I had to make RAMDISk more than 40MB as after setting them at 40MB it comes to only 20mb free.
Anyway, I had decided to hold it for a while as I had use Walker's methods in creating a new ini and only editing the resoluton, darn changes, etc. The good news is that it really ran smoothly I'm able to run the game for an hour without crashing, before that I had crashed like every 10-15,30minutes. So there must be something wrong in my ini, I guess regenerating the ini, remove bloat, abomb really helps especially the ini part.
Hopefully this really stops the crashing, though there's always this thing in life that the problems will always comes in a creative way whenever we have a solution. So the learning never end and never give up. Thanks to all who had helped to troubleshoot. Cheers.
Edit: 1 more thing, I had also removed Crowded Cities as I guessed the scripts also had somewhat an impact to my crashing. However I had also installed back MMM with the lowest spawn rates and also TIE (because of the NPCs it added)
