Random Lockups

[Kc7mxo]

I reinstalled civ3 after the 1.17f patch came out, and now the game randomly freezes after a few minutes of playing. I can ussually play for 5-10 minutes, and my computer locks up entirely.

My system is as follows
Amd Tbird 1ghz
Asus A7Pro Motherboard
Visiontek Xtasy Geforce 3 Ti 200
Windows ME
Creative Labs Xgamer sound card

I'm using fully updated for everything in my system. Is anyone else having similiar problems?
