Hi nicc09,
Welcome to Microsoft Answers Community Forums!
Method 1: If your computer is having problems running the Aero desktop experience, which includes effects such as transparency, try using the Aero troubleshooter to fix the problem. It checks for common compatibility issues with running Aero, such as your computer's color, theme, and power settings and your computer's video card.
Open the Aero troubleshooter by clicking the Start button, and then clicking Control Panel. In the search box, type Troubleshooter, click Troubleshooting, and then, under Appearance and Personalization, click Display Aero desktop effects. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

For the aero feature to work the requirement is to have:
A Direct X9 compatible graphics processor with a Windows Display Driver Model(WDDM) driver.
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)
