Random Assorted Crashes: HALP!

[Ichigo]

I have up to Seasons installed, and I've got a brand new graphics card. The problem is my XP will reset itself during gameplay, and come back up with the generic "The System Has Recovered From A Serious Error". The other problem is if I travel to many community lots, I get "The Application Has Crashed, Application Will Now Terminate". I have no hacks, just some CC. I'm only in Riverblossom Hills with all the premade families deleted. I can play for up to six hours a session before it crashes sometimes. I'm hesitant to twork any graphics settings down, as the game defaulted at the highest settings.

EDIT: It's also phail in a custom neighborhood.

FURTHER EDIT: Teh card is ASUS AH3450.

Do you have a lot of CC? Compare the size of your RAM to that of your Downloads folder and see what you get. If Downloads folder is bigger, you can increase the virtual memory and the random crashes should stop. I have no idea if that is your issue here, but it's worth a try.

Downloads folder:53,800,960 bytes

In relatin to my space, that's miniscule.
