Monitor goes into power saving mode

Hi, I am having a strange problem here, what is happening is whenever I go to view a quick time movie online or start up Picasa 3 (Google's photo organizer) or if I go to the video maker in Roxio Creator 2009 my monitor shuts off and says entering power save mode, so I have to restart my computer every time it happens.

At first I thought it was my monitor, because the one I was using was from the stone age (it was just a temporary monitor until I found better one), so today I splurged a got a 22" View Sonic VX2233WM, hoping that it would solve my problem, so I went to the Red Giant Software site and watched a quick time video and a second into the video my monitor shut off, so I restarted my monitor and Installed the monitor driver and tried again with the same result, so then just for good measures I tried one last time, in case the monitor driver needed the computer to be restarted, and the result was the same as before.

So I am wandering if any of you have had this problem and/or know how to fix it.

Here are the computer specs:

Mother Board: P5W-DH Deluxe(with all the necessary drivers)
Processor: Intel Quad Core Q6600
Video Card: ATI Radeon HD 2600 XT(With the latest driver)
Operating System: XP Professional 32Bit

Thanks in advance!!!

Control Panel, Power Options......god I would hate to think I spent money on a new monitor just because I needed to change the power saving settings in the control panel. I guess you probably wanted a new monitor, and you are really happy with it though?

I swapped out my video card for my 6600gt card and now the problem is completely gone, so I think it was a compatibility issue with some other hardware, so I will just stick with my 6600gt card.
