Ok... Found fix
I was installing windows 7 in Uefi mode and it appears as though this
Was slowing down the pc or media center in particular.
I attempted a dozen install attempts and I got the same results.
Slow and unstable.
I finally did another reinstall and chose non uefi from the boot
Menu, installed all the same way, same drivers
... Everything the same.
Media center ROCKS!!
So fast and stable, it's not even funny!
So in my story... I dont like uefi... I've lost too much sleep
And I'm happy it's all done!!
Anyone else experience this?
