GUI issue

I have successfully installed Red hat linux 7.2 on my PC.
But During the installation i saw the following messages

"starting anaconda....
probing vedio card:unable to probe
"

In Xconfiguration step of installation ,The installer could not identify my video card.

Finalle when i start the system it is starting only in text mode,but not in graphical mode.
Is there any problem with video card?If so,How can i solve that problem?

cheers

Certainly, there's a problem with the video card, it's either faulty, or the OS drivers are not suitable / not found. Check your VC model, and search for drivers at the vendor's site, or check the supported hardware list - your VC / chipset may not be there.
