What drivers did you install? are there any older drivers that you can use? the drivers are vista or 7 correct?
Follow this link to see the drivers i installedhttp://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4063&lc=en&cc=us&dlc=en&sw_lang=&product=3860488#N287
i realized that when i disable the display adapter drivers in safe mode and restarted the comp works fine.
then when i check the display in screen resolution in advanced settings it gives the adapter information as UNAVAILABLE i.e the Chip, DAC Adapter string etc.
am sending the information about the directx components and drivers installed to the Toms hardware email
