How to improve my desktop performance for Windows Aero?

Just some ramblings from Charles

I bought my laptop last few months ago.  The performance has been satisfying.  The only hindrance is with the random hangs that it gave me along the way.  I got really frustrated and asked around how to improve my hardware problem (I am guessing it could be an hardware issue).  Then I found this interesting feature called Windows Experience Index in my Windows 7 64-bit Ultimate Edition.  It assesses the key system components on a scale of 1.0 to 7.9.  More information can be found below.

What is the Windows Experience Index?

The Windows Experience Index measures the capability of your computer’s hardware and software configuration and expresses this measurement as a number called a base score. A higher base score generally means that your computer will perform better and faster than a computer with a lower base score, especially when performing more advanced and resource-intensive tasks.

Each hardware component receives an individual subscore. Your computer’s base score is determined by the lowest subscore. For example, if the lowest subscore of an individual hardware component is 2.6, then the base score is 2.6. The base score is not an average of the combined subscores. However, the subscores can give you a view of how the components that are most important to you will perform, and can help you decide which components to upgrade.

You can use the base score to buy programs and other software that are matched to your computer’s base score. For example, if your computer has a base score of 3.3, then you can buy any software designed for this version of Windows that requires a computer with a base score of 3 or lower.

The scores currently range from 1.0 to 7.9. The Windows Experience Index is designed to accommodate advances in computer technology. As hardware speed and performance improve, higher score ranges will be enabled. The standards for each level of the index generally stay the same. However, in some cases, new tests might be developed that can result in lower scores.

It’s frustrating to see my laptop to have a rating of 4.9 on my graphics.  I would have expected it to be around 5 to 6 at least.  Even if it is so, it could be the main cause of the random hangs on my laptop.  (I am carrying a Dell Studio 1557 by the way.)

Here’s the screenshot of my Windows Experience Index.

After checking out on improving my graphic card performance, I installed whatever drivers that can help.  In the end, my result is still the same as 4.9 for my Graphics.

I google about how I can improve my desktop performance for Windows Aero… And it turned out that I may need to upgrade my video card in order to enjoy a better rating.  (The objective is still to resolve my random hangs that I am having.)

I guess the only way out is to upgrade my graphic card… But does that going to achieve my objective?  :(
