NVIDIA power indicator error

[esm]

Hi guys, i am posting this question on behalf of a friend who has an ongoing problem with his computer.
Basically everytime he turns on his pc he gets the following error message :

"The Nvidia system sentinel is reporting that Nvidia-powered graphics card is not receiving sufficient power.

To protect hardware from potential damage or causing a potential system lockup, the graphics processor has lowered its performance to a level that allows continued safe operations."

This error can be seen through this link: http://img155.imageshack.us/img155/6202/mypccn8.jpg

Although this error message occurs is does not affect the performance of the computer, the problem is it pops up several times and tabs out of any other programs he is using. The specification of his computer is as follows:

AMD 3500+
Asrock 939dualSATA
512mb
550 watt psu
Xfx Geforce 6600gt 128mb
Nvidia drivers 93.71with nvidia control panel thing

As you can see the power supply is easily sufficient for the specification of the computer. Would it be possible to uninstall the control panel which is making the error popup and install third party drivers for the card? Any ideas would be appreciated because we are out of them!

Many thanks

You could try uninstalling the NVIDIA drivers and control panel and downloading the drivers from XFX's site.
That's weird because you shouldn't be receiving the error message. What make and model is the power supply?? It may state 550 but it may not necessarily be rated at 550.
