Debian Newbie need help

[p3qwestra@hushmail.com]

Hi.

I need help please.

Because I'd like to move to Debian, I have tried the Debian 6 Live 
CD. However, because the screen refresh rate is fixed on 60hz, I 
cannot proceed. I am unable to change the rate and leaving it on 
that setting means I get migraine. My graphics card is a 256MB 
NVIDIA 7600 PCI-Express which can handle much higher resolutions; 
as can the monitor - an excellent Gericom CRT which can also handle 
much higher frequencies. I've tried to find help but am lost in the 
maze of topics none of which seem to relate. However, from a Google 
search, this would seem to be a long standing problem and not just 
with Debian. Interestingly Puppy has no problems in giving me the 
needed screen and refresh options.

Thanks in advance,
