All I did was unplug my existing CRT monitor and plugged in the new LCD
monitor and rebooted the PC.

Inital boot screen came up as well as windows logo etc but then screen
went black and nothing at all. Tried starting up in safe mode and still
the same.

So, plugged my old monitor back in and rebooted. Still went black!
Started in safe mode and it worked OK again.

Unfortunately, could not get it working again in normal mode. Tried
system restore - no joy. Repair install - no joy. In the end had to
reinstall XP to get it work again....

Any ideas why this happened? How can changing a monitor totally screw
things up?

I'm a bit scared to try my new TFT again now...
 
You probably had your desktop set to a resolution and/or refresh rate that
was beyond what your LCD screen could display.

Hi there Bertie,

Did you happen to change the Monitor while the PC was on or off?

If you changed the monitor while the system was on, you may have either
jolted the video card, or created a grounding short in the system which can
trash your video card.

Please let me know.

Best Regards,

I think you're right about that. So whats the proper procedure for
replacing a monitor with a LCD?

Should I install the LCD drivers and decrease the current refresh rate
with the CRT installed, then power down, switch monitors, and reboot?

I still dont understand how it screwed up things when I switched back
to the CRT though?

I did do it while it was on - not clever I know.

I think my video card is OK because all seems well after reinstalling
windows.

Just switch the machine off. Unplug the CRT and plug in the LCD. Switch back
on. Windows should find new hardware and either set it up automatically, or
ask for the CD with drivers.
 
jsut set the resolution to 1024x 768 and a refesh of 60hz on the CRT..

shutdown the pc and attch the LCD then reboot....

If windows wants to install a neew driver for the lcd let it search for one
on the mancufacturers Cd that cam with the LCD...

most LCD s arwe best working in there native state ... Eg for 17" its
generally 1280X1024. i think 15" are 1024x768...

once booted you can now fiddle with the settings.....

Your BIG mistake was switching monitors with the power on. That
is a NO NO. It is a wonder that you didn't fry everything.

Must admit I regularly do that. Maybe I better stop...

Switching monitors with the power on is no more a problem than switching
USB devices. The issue is that the OS does not always detect that you
switched monitors and it will not adjust the sync rate if one can't
support what the other was running at.
