Woa, that's odd. Never seen anything like that before. Try to use "Update Driver" function under "Properties" page and see what happens?

Already tried it before, when I click "Update Driver" it will install back the older version driver...

This is the last thing I can think of, it'll definitely work on a desktop and not sure about spoiling your laptop. Try to overclock your integrated graphics. I've never heard of anyone doing it on an integrated graphics solution and worst still in a laptop. But if you've got the money to spare, you can give it a try. I tried to OC my old desktops graphics (GeForce FX5600XT) with a score of 3.0 to 3.5.

Thanks for the suggestion. Since the current driver I used was downloaded directly from ATI site. Better for me to wait another new graphic driver from HP Support Site.

Any trusted application to do that?

The applicant will be you, you'll have to visit HP Support Site and the application will be your internet browser.
