Windows 7 Windows Aero gone haywire.

I've been enjoying my new computer for a while now, but windows keeps asking me to revert the colour scheme to improve performance

Your computer's hardware and video card must meet hardware requirements to able to display Aero graphics. Check that your computer meets the minimum hardware requirements for running Aero:

• 1-gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor
  
  
• 1 gigabyte (GB) of random access memory (RAM)
  
  
• 128-megabyte (MB) graphics card
  

Aero also requires a DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver, Pixel Shader 2.0 in hardware, and 32 bits per pixel.

For best results, you might also want to follow these graphics processor recommendations:

• 64 MB of graphics memory to support a single monitor with a resolution that is less than 1,310,720 pixels (for example, a 17–inch flat panel LCD monitor that has a 1280 × 1024 resolution)
  
  
• 128 MB of graphics memory to support a single monitor with a resolution from 1,310,720 to 2,304,000 pixels (for example, a 21.1–inch flat panel LCD monitor that has up to a 1600 × 1200 resolution)
  
  
• 256 MB of graphics memory to support a single monitor with a resolution greater than 2,304,000 pixels (for example, a 30–inch wide-screen flat panel LCD monitor that has up to a 2560 × 1600 resolution)

So why would I be running out of power // resources //// or need to revert my colour scheme to save power in the first place.

The message appears like a warning message, like I'm on a knifes edge, but the reality is I should never get this message in the first place.

Why am I getting the message? I know how to disable the message - that is not my question.
