Windows 7 Aero Requirements
If the problem is Windows 7 Aero themes not working, your computer may not meet the minimum requirements to run Windows 7 Aero. According to Microsoft, here are the absolute bottom requirements to run Windows 7 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.

- 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), that
- 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)
