I recently bought a new desktop; an Hewlett Packard, 2.5 Ghz, 750 GB Hard drive, 8GB RAM, Nvidia Geforce 9100 and I'm experiencing a weird problem with it. At first, everything was fine and everything went down smoothly. But then, I decided to manage a user account and make an account for my mom, dad, and mother (since this will be a family computer). After creating an account, I logged into my sister's account but HP Advisor crashed. That's not all. I got this error code where it said "MUIStartMenu stopped working" The computer detects the trouble and closed the MUIStartMenu or watever that is (I don't even know what its for, I checked google and found nothing). But the annoying thing is that my mom wants to use Internet Explorer 8 but it wont even open up. I tried to system restore but it didn't even work. What do I do? D:
