   Hello all,

   I have a nice laptop called Acer 8930G

   Core 2 Duo 2.26GHz
   4GB DDR3
   2 x 120GB Black Scorpio hard drive
   Nvidia 9700M GT 512MB

   I did a fresh install of Windows Vista 32 bit with all the latest drivers. No Acer crapware installed. I haven't been on the Internet yet so no viruses/spyware.

   Eventually the browser (IE 7) became sluggishness (within hours after a fresh install). I expect IE to open/close smooth like Windows animation.

   I even tried Google Chrome, Opera and etc. All have the same result. Strangely, open/close 'My Computer', 'My Document' etc are very smooth.

   Why is that? Hardware fault?

   Try to fully update your vista and other software first, updates are there for a reason. No known issue btw.

   Then again, you say you havent been on the internet, so why use a internet browser? just wondering...

   Thank you for your suggestions, but I have found the solution.

   This might be very useful information for you if you ever come across another customer who might have the same problem.

   The problem I was having is when minimizing/maximizing a web browser (doesn't matter which browser it is), it caused it to stutter and the vertical scroll when scroll up/down a page was very chopping/stuttering.

   The problem came from the Nvidia video card, which mine is a 9700M GT and Nvidia is using a throttling program called Powermizer. Now, the Powermizer set the video clock speed to the minimum level until you are doing more intense 2D/3D graphics, it will kick-in and the clock speed reached the maximum performance.

   As soon as I opened up a browser, the video clock speed reached it max (to deal with the 2D effect), but it wasn't quick enough. It is too late by then.

   To solve that, I used a program called Powermizer Switch to turn off the throttling function only under AC mode and on when in battery mode. You don't have to have it running in the background. Just set it and reboot.

   No more 2D/3D stuttering or sluggishness.
