    Hi, as above my PC has started having boot up issues and the Sys fan is reading 0rpm but when I've opened up the casing all of the fans are running fine.

    Thanks

    Hmmm guess this isn't a very common problem then, could it be any kind of driver issue?

    I've recently upgraded from XP to windows 7 but updated all the drivers I could find from the manufacturers website.

    You should provide some details about your system specifications and operating system. Without them it's difficult to provide anything but the most general of suggestions.

    You could also define the problem a bit better. For example, you could provide some details as to what kind of "boot up issues" you are having. Anyway, with that as a start maybe someone will be better able to help.

    Does your sys fan have a 3 pin plug? The third pin is the speed sensor.
