I'm currently going through the process of educating myself about these debugging apps, but I'd appreciate some help the problem that's started it all. ---------Skip if you just want to read the mini dump---------- ============================================== ============================================== XP SP2 AMD X2 4200 ABIT AN8 Ultra 512 x 2 ATI X850 Pro The system is crashing whenever I launch specific apps or specific opperations. All my drivers are new, the memory has been throughly tested, and I don't believe I have any spyware or viruses. I'm assuming that one of my drivers might be corrupt or there is a bad registry entry. I've got all kinds of symptoms: ---------------Error and reboot------------------ Mounting an image in Daemon tools 4 will cause it. Closing Notpad will cause it. Closing the MMC will cause it. Closing System properties will cause it. <I now fear closing things...> There are a few other apps that will cause it as well, but most don't cause a lock up. These will cause it every time. I can get around the issue by force quiting the app through the task manager. ---------General Weirdness-------------------- The system manager that is accessed by right clicking on "my computer" is largely unusable unless I boot up in safe mode. The logical disk manager "can not find the registry key", system policy won't load, and most of the other apps in that group don't work. The Services mmc accessed through the "admin tools" folder in the control panels reports a script error when opened and will not display the help information for any of the services. I believe the error was something like "cannot find OLE <something or other>". At any rate, it works perfectly in safe mode. However, if I open the properties on any of the services, that causes a system lock up and reboot. Anyway, I'm hoping these mini dumps will shed some light on all of this.
