I actually have 2 questions.

I recently had windows xp installed on one of my computers. After I log off windows and turn the computer power off, about 20 minutes later it turns itself back on.
Any Ideas on how to stop that or what causes it.

The other is, does anybody know where I can find a list of processes that should be running on my task manager, or a reference list to check against and see what the ones I have running are. I have no Idea what all of them are. It seems that I have alot of programs on there that I have no clue as to what they are.
Thanks in advance for your help.
