Hi
the error does not specifically state a certain file. it just pups up when she turns on the computer and it just says rundll error. I have asked her if she downloaded things from the internet but she doesn't know. Also the only way i can get into her register editor is that I have to go into safe mode. I have tried to uninstall some program from the add/remove but some of the programs I can't uninstall. I was going to restore her computer to an earlier time but the last restore point is after the error started. I was looking to see if I could get something earlier but no go. I hate to have to restore to factory new but if all else fails I might have to go that route. But maybe I'am lucky and I can get some help
