I didn't add or change anything. One morning in the middle of a game I got the blue screen of death. Since then, it has happened more often. It gives me different messages also. So I can't narrow it to one problem. I get; memory_management, IRQL_NOT_LESS_OR_EQUAL, and a couple other ones. Sometimes it has no error code at all. I restored to an earlier version. It happens less, but still happens now. I just downloaded the newest drivers for my Nvidia card, it still blue screened once since. Is it possible I have a stick of memory going bad ? I'm at a loss and afraid of using a registry cleaner due to the horror stories. Please save me from the insanity.
