    videocard fan turning on while in sleep mode


    I have a computer running windows 7 32-bit that I am using as an HTPC with WMC. At night when I am done, I push the power button (sleep mode?) on the remote and it puts the computer to sleep. For some reason, the video card fan starts up at full speed at 4:30 in the morning but the computer is still in sleep mode. Can someone tell me what is causing this and can I stop it from happening. The video card is an ati x800xl.

    Have you got any scheduled tasks to run at that time?

    My media machine will run it's fans while waking up to record something. I can't hear the graphics card fan itself, but I can see the fan speed in my LCD status display. From what I understand, some TV capture cards can use the GPU for encoding chores. Not really sure how that works, I just read it somewhere.
