Did you install your ATI drivers? (

thanks for your reply
i tried but i couldnt find the right driver i did download a driver but i think it is not the right one if you know which driver i sould download please let me know

Its an old mobility chip and its long discontinued by ATI. In the past you couldnt install the desktop drivers on the mobility chips (unless you tweaked the .inf files) but had to install the drivers supplied by the notebook manufacturer. Since Compaq got bought by HP you have to search for an XP driver there but I dont think that they have one.

discontinued hardware + new operating system = headache

This is what ATI has to say about it:
