I have a Dual Core 1.8Ghz Pentium 4 running Windows XP. The machine restarts fine, but when I select Shut Down, it logs off as usual and switches the screen off, but the power light and harddrives etc remain on, almost like a sleep mode. Is there some setting that I have to change to get it to shut down? I have to hold the power button for 5 seconds everytime to get it to turn off properly.
