nvidia geforce2 clone problem, Help!

Hi,

I have been using the nvidia geforce2 for quite some time to watch video on
my tv using the tv out signal via a wireless sender.

When I choose the clone mode, I can watch the video on the tv but on the
monitor the video was blank but I could still access all the functions of
the pc and it was just a matter of changing the settings of the feforce2
back to single view for the monitor to view video again.

This was not really a problem, however I was playing around with the
settings of the geforce2 and tried the Dual control, which was a mistake.
All video was sent to the TV and nothing was left on the monitor. All I
could see was my background photo. I was unable to use the pc and every time
I restarted the PC it was the same.

I unplugged the geforce2 card and connected the monitor to the onboard
graphics card - I could then use my pc but of course not send video to the
tv as this has no TV out.

If I install the geforce2 again and start the PC with the monitor plugged
into the geforce2, the monitor is blank.

If I start the pc with the monitor connected to the onboard graphics card
then change it to the geforce2 everything works fine. I changed the setting
s of the card to normal and everything works ok......

until I restart the computer again and it reverts back to a blank monitor,
even though the settings on the card are set correctly to provide video only
to the monitor.

It's driving me crazy!! Can anyone help???
