Alienware Aurora R4 - Command Center and windows 8.1

Hello

I updated windows 8 to 8.1 and now the command center and the fan control doesn't work properly.

Before updating the system fan were loud just on first seconds after boot. Now they continue activating loudly with some seconds interval since i log onto desktop.

Just after updated the command center crashed so i removed it and reinstalled and now i cannot control anymore the effects or anything on the command center.

When i shut down the pc some of the led continue blinking like the pc is in suspend mode.

I'm searching since my upgrade for some fix but found nothing.

Anyone with same problem?

Thank you and sorry for my english :P
