Service Pack 1

I have been trying to install SP1 on Vista. It goes through the install process but after it restarts i get the message acpi.sys is missing or corrupt. I have turned acpi of in bios and my pc wont start at all. I had previously installed sp1 rc and then installed it.

I cannot be certain on this as I do not have access to your computer. Did you uninstall the Vista SP1 RC? If not that must be done before you install the final version of Vista SP1.

I have uninstalled it but if i remember correctly i think i had to make an adjustment to the registry but cant remember. Also i don't have sp1 coming through windows update i get it from a separate download

It could be the down loaded copy that is giving you issues.
Have you tried using the Windows or Microsoft update method?
If not, try it and then let us know what happens.

I am unable to get the download via the normal update system. I will download the file direct from microsoft again and see if it works.

I am also unable to get the download from the Windows update, but it is because of the sound driver which is prior to the version that SP1 requires. Are you sure you do not have a driver incompatibility issue?
