New HTPC Windows 7 will not sleep when it should

#1
I have changed my HTPC from a tower to the HTPC case. New everything except the Ceton InfiniTV 4 PCI card/cable card.
Have identical Windows 7/64 Pro systems. Tried to copy all the power / sleep settings.

New HTPC system will not sleep when it should. It is set to sleep after 10 minutes.

The machine wakes up between 3-4AM and 3-4 PM every day.

After 10 minutes of idle after Windows Media Center stops recording it goes into Sleep but wakes up seconds later.

Tried various combinations of settings. How can I get sleep to work correctly????

Hardware
MB Gigabyte GA-78LMT-USB3, AMD Fx6300, Wireless USB Netgear N900

The last time it woke up the system event log said it was the pci bridge

Wake Source: Device -PCI standard PCI-to-PCI bridge

It never goes to sleep on the timer of 10 minutes which it is set to.

Any ideas??
