No receiver required. My HTPC is directly connected to the TV, and it does the same thing.
I've used the workaround of disabling the ATI driver helper service, which needs to be done every time the drivers are updated. I know it's a problem of the TV being disconnected when you turn it off, since I hear the device disconnection sound from Windows when the TV turns off.
