I don't know if this is the correct place for my question, if not by all means please move it.
I have the AMD Radeon HD7900 card with Windows7 Ultimate x64 installed. I use the 'Power options' in windows to shut down the display and secondary Hd when left overnight or for some time when downloading off the net.This is set to 1 min. Now, the AMD card shuts itself down to 90+% when in this mode(fans Off) although turns back to full power anytime from a few seconds to some minutes after this. How can I set it so the card remains in the almost off(quiet) setting. I have been reading everywhere to no avail.
