If you actually shut windows down, the computer will power down. In this case, will the capacitor discharge, and then restrike, or will the computer stay shut down until the power is killed via power strip and then turned back on? If the computer restarts due to the capactitor before you could kill the power, then you would have to set up the computer to not kill power to the MOBO on windows shut down. I had a windows 2000 machine that went to a black screen that said "you may now turn off the computer" when you powered down windows.

If your motherboard has both a "power" button and a "reset" button then you should be able to do it either way. Shut down Windows or shut down hot, personal preference.
I know my motherboard has both buttons in use.... therefore the "power" button only turns the pc on after an actual power down. (turning power strip off)
Without killing the power strip first, I have to use the "reset" button to re-boot. The "power" button does nothing no matter how many times you push it unless you actually shut the power strip down first.
So if the cap is on the "power" switch pins as Peale has mentioned then it should only kick it on the one time when power is turned on at the power strip. It should not reboot if you shut down through Windows before powering down the power strip.
(did any of that make sense ???)
This of course is dependant on your PC setup and I know would work fine on mine

And since you bumped this, it is worth mentioning that most mother boards have a 'turn on when power is detected' function. That is how I have my MAME PC set up. No need for this trick at all.

I did some site reorganizing lately and moved stuff around. I thought I changed all the links here - guess I missed one. Fixed.
