Please excuse some of my lacking expertise here.
My daughter got a new laptop roughly 2 months ago, an HP. It has Vista as its OS. It has had absolutely no problems. We went on vacation a week ago, and she shut the computer down while we were away. When we returned, upon rebooting, she had no sound. When we try to go into Control Panel and adjust the volume, it tells us there are no sound devices installed. But when we go to Device manager, it says they ARE installed, working properly and have the latest drivers. When we attempted to adjust sound again, we got the message that no sound was present because Windows sound service was no enabled. We clicked to enable it and got the message that the host program, Rundll32 had "a problem" and was not working. Microsoft had absolutely no fix for this at their site. So, what do we do? Should I use a registry cleaner, should we just backup necessary files and try to reinstall Vista from scratch?? HELP!!
