first of i have to say i love dis forum. anyway my problem is i want to know if my mother board has an onboard graphics card and how do i disable it?

Look in Device Manager.
Why do you want to disable it?

To my knowledge, the P45 chipset does not have any on-board graphics. But you can check your graphics easily. Type msinfo32 into the Start/search, hit Enter and look under Components > Display.

becos i have 2 ati saphire 4890 and i dont want any conficts between my cards and the onboard card if there is?

maybe u guys can help me cos i dont know wat to look for.

It says it right on the first line after "Name" - ATI Radeon HD 4800 series. So you have nothing to worry about.

thankyou whs .
