I leave my computer running WMC and put it to sleep at night. I can see the blue light (power on) blinking slowly indicating that sleep is occurring. The next morning or sometime after the computer is put to sleep the blue light is on (not blinking) at this point there is not disk activity(red light blinking). I try to wake the computer up however nothing works, Mouse, keyboard, PS2 keyboard, Power buttton pressed fo 5 seconds, or reset button. So I have to uplug power, wait five seconds, and restart. The first thing that comes-up is "windows is resuming", then nothing, then corrupted graphics, then blank again, then a variety of windows screens, and finally a full screen of window and lots of disk activity. I have removed most non-WMC software to narrow problem and have checked to see what programs are running at night and what errors I am getting. The only thing significant is the warning about optimization (done at 2:00 AM) unable to complete due to slideshow. Any ideas.
