I dont know what did it, but suddenly I seem to be unable to open most of the items in the control panel including display, add remove programs, And system. It seems that all the ones that wont open are ones that open into a new window. I have been able to get them to open a few times, twice directly after doing a registy clean with Ontrack system Suite. I don't know if this will help but All I've installed recently is mem turbo, ontrack system Suite, and drivers for my digital camera. I tried a system restore but the one that went back the farthest wasn't far enough... Any Suggetions?
