I'm currently not on my computer that is having the issues as I am at work but I will try and answer some/all of your questions.
I have already gone through all the drivers
in Device Manager, right clicked them all and selected Update Driver
. All of them said they were up-to-date.
Yes I did upgrade from another OS, I used to have Windows XP Media Center Edition 32-bit installed.
I used Windows 7 Upgrade Advisor before I installed Windows 7 and it said all was good to install Windows 7 Ultimate 64-bit. It did however say that I would only be able to do an Custom install and not an Upgrade, so I did.
I will run Windows 7 Upgrade Advisor again, though, to see if it says anything about Audio drivers/Tv card drivers if that's what you wanted to know.
So are the dump files all saying that the issue is my Audio driver and that's it?
Thank you so much for your help so far
