unpsupported mode

[Guest]

Window XP Home eventually starts ok.
But the normal DOS and Windows screen that used to show the loading bar
scale doesn't appear and there is a blank screen with an error message that
pops up about 7 times before XP starts that says "unsupported mode" together
with a V (Value) and H (value).
What does this mean.
It all started when I replaced the on-board shared graphics card with a
Radeon 9250

The H and V values are the pixel numbers corresponding to the location on
the monitor of the dispaly.

Boot into Safe Mode, open Device Manager, delete/remove ALL instances of the
display adapters you find, reboot, and Windows will re-detect the new video
card (Assuming you did shut off the on-board video in the BIOS). Then you
install the latest driver software from ATI.

The H and V values are in fact "H 35.9" Kh and "V 59.9 Hz" which sounds like
some type of frequency thing ?

Did you remove things and reboot?

Can't find anything to delete in the BIOS ?
