Scroll lock shutting down the computer

[Toshio Tenma]

Recently, I was playing mugen and I paused it and increassed the frame with Scroll Lock in order to advance frame. However, my machine shutted down instead as if I pressed the poweroff button. Any idea of how I can fix it?

Check your Power Options, in Control Panel.

It doesn't work like that.
