I'm running windows 98se with all the updates from MS. Here's my problem, Put a new dialup modem in my pc, loaded the drivers, everything went just fine, I can get on line, can do everything within windows. But when I try to change display resolution weather from control panel or right click desktop/properties/settings I get a dialog box telling me I'm trying to preform an illegal operation,operation will now close [rundll32 error]. don't know why putting a new modem would have anything to do with display settings, but prior to putting in the modem we had a bad electrical storm, power went out and the old modem cooked. Nothing has been the same since. Anyone got any idea's that may help me out? Thankyou.
