[Solved] Winows 7 power management

I just jumped ship to W7 from XP, skipping the whole Vista episode. I have been up and running now for 2 days and I have to say I like it.

After trying to overclock on W7 I was having troubles and it would shut down. I looked at my core temps and noticed my cpu and voltages were right down to min. I flashed bios and checked all drivers all were fine. I googled it and all I found were ways to change your cpu from bios to a stable setting. well I tried all that and still samething. I went into control panel to double check all drivers currently installed and BAM there it was power management. HAHA so cool, not sure if I missed that in Vista but I thought it was neat.

So here is my question:
What setting should it be on?
I like speed and play high end games and downloading here and there.
If I go High performance will just jack up my electric bill or if i go to BALANCED will it save on my bill and give me the performance on demand when needed or is like a disel engine and take a bit to perform under stress?

Any idea would help thank you and sorry for long post.

amd 940, my question is, in windows 7 in power settings if i click balanced power settings will I get the same performance as I would on high perfomance power setting, even at stock cpu?

Im pretty sure i know what i'm doing lol and very familiar on OC'n, just new to windows 7. And no its not just for laptops. You need to read up on it. There are drop down menu's to reduce your cpu power your harddrive power, monitor, and so on. You can set the max or min or in between settings on everything I mentioned. When your pc is just sitting there it does not need all that power, especially all the cpu power. So it kicks it down and lets it cool. If you watch and monitor the cpu it will go nuts when you open programs.

Who said anything about being green. All I asked was for ideas on what settings people are running and if it effects how the system runs. I said I noticed it when I was clocking my pc that it wouldnt allow me to because of windows default settings. WOW you can quote me all u want when all that quote means is what I found in google.. Nice specs there, maybe try new windows before you start being negative on peoples posts.
