OK, guys. New to this forum. Hadn't played SimCity4 in a while but was bored this week and was going through my old game stack. The game has crashed on me at least 6 times. 4 of those, it just crashed right to the desktop almost instantly. The game was completely closed out but my PC worked normally. The other two times,the game hung for a few seconds. One of those two times, the sound stuttered for the duration of the hang. Then after 15-30 seconds... crash to desktop. That was the only time I was playing Windows Media Player, listening to music in the background. My PC is fairly new (3-4 months) It is an Intel E6700 Core2 Duo processor Nvidia 8800GTX Vista Home Premium 32 2 or 4 gigs RAM (can't remember) The version of the game I have is the big box Deluxe Edition. The game crashed unpatched. It then crashed after I patched it at the official site. It then crashed after I installed that SKU1 thing. I have not added any mods or altered the game in any way. I run other games just fine. The first couple of times I crashed, I blamed Vista. Then I came here and read someone saying to run in Windows Compatibility mode. I did that. No good. Then I right clicked the game to open it and ran it as an administrator. No good. Then I checked under properties "Always Run This as Administrator" or whatever it says... That seemed to help a little although it may be coincidence. Until I did that, my cities crashed with populations of 70-90,000 people. This last time, I got to 150,000 before crashing. I had not run an antivirus program in the entire time I owned the PC (stupid I know...). Today I went and bought Norton 360. No virus. I have defragged my hard drive. I set the swap file to 4096 or whatever just now following you guys' instructions but I doubt that will help because the swap file was already set to close to that (3800 or so). I would be glad to tell you guys whatever you need to know about my exception reports or dumps or whatever. The game has crashed at least six times as I said and there are only two of them. You guys will need to tell me what you need to know off these reports as I don't want to post the entire things. I'm fairly *****ish guys so speak sllloooowly. And thanks in advance to anyone who tries to help.
