XP get rid of Cannot Install this Hardware message

You could try preventing XP from "installing" the monitor each time you boot.
Go into Control Panel/System/Hardware/Device Manager.  Click the plus sign next to "Monitors" to expand the list.  Right click on your monitor, choose Properties.  Under "Device Usage," choose "Do not use this device in any profile."  Click apply, reboot, see what happens.

google for a driver for your monitor  - and install that
or try windows update>optional updates to find a driver
also -  is it showing in error in device manager ?

Right click on you My Computer / Click properties / on the tab click Device Manager Look for a yellow question mark or exclamation mark then expand that area if it say unknown device you have to install new drivers for that monitor or simply update you video card if you have any, you can find the driver from the manufacturer site or if the monitors comes with a CD just pop it in and you are good to go.

Go to Samsung site to download the correct Samsung monitor driver then install it.
Use:
Choice 1:  Automatic Download and Update Samsung Driver
or
Choice 2:  Select your Product family to download the drivers

Installing the correct driver will stop the New Hardware Installation Wizard.

What happened was it made things worse! After setting the device to "do not use" the wizard error came up continuously. After close one dialog box another would pop up immediately. The only way to stop that was to go back in and re-enable use of the device.

nobus, Sarahiko: The monitor came with a CD, but that wouldn't install. I suspect manufatureres are dropping driver support for XP. That was the case with an ASROCK motherboard I recently bought.

Michael-Best: As mentioned above, the shipped-with CD did not install. Also, I was mistaken about the brand of the monitor. It is not Samsung. It is HP Pavilion IPS LED Backlit Monitor.

I did not notice your link to stopping the New Hardware Installation Wizard. I'll try that next.

nobus: I had tried using the Wizard to find a driver, both at boot-time and from the device manager. No luck. I also had no luck with the CD that shipped with the monitor- it gave no errors except "cannot install." I assumed the CD would be latest-enough, considering this was an XP system. However, in the interest of being thorough and following you suggestions, I went to the HP website and downloaded the requisite driver. And guess what? It worked!

Thanks!
