Hello – I need some help……Yesterday morning I switched my PC on and go the black screen asking if I want to start in safe more or normal. I selected normal and then got a message that I need to run a disc scan so my computer automatically started to do this. This happened a few times and when I got to my desktop in the end I got a message from Norton that I need to run a virus check because my computer was not protected. I then had to force my computer to d/l the latest Norton aniti-virus check. The antivirus is now updated but each time I run the virus check it is extremely slow and when it get to system 32 to the file called – windows\system32\config\audiossrv.dll it just freeze. Also, when I work it just freeze.Any idea what is wrong. It is a dell laptop with windows vista on it.Thanks for any help.
