I used to install the original windows XP SP3 and after done, when putting my computer into
Stand By >>>
Fans,
Mouse &
Keyboard are still active after
Stand By.
And this is to enable me to bring computer from
Stand By by pressing any key or moving mouse.
Nearly a year a go, I installed the same original windows XP SP3, and after done, when putting the computer into
Stand By >>> A strange thing happened ;;;

Fans stopped , Mouse & Keyboard also off.
The only way to bring computer from Stand By is by pressing the Case power button.
Knowing that I didn't change anything or add any hardware or change BIOS.
And this problem is until now when installing the Original XP SP3 or Mr. Maher's release.
But, I've tried a release called "Micro XP" a few months ago >>> This problem didn't happen with this release, and it wasn't happening with any release before the last year. Suddenly, It appeared to me from nowhere. !!!
It doesn't matter to me

except that I want to know the possible reason for that. Or what is the service responsible for that ? Or anything !!!
Thanks for your support.
