What would cause Photoshop 6.0.1 to give me an error message, right after the loading fonts initializing screen, that says "Unable to continue because of hardware of system error. Sorry but this error is unrecoverable."

I have uninstalled, and reinstalled and still get the same message.

I am running Windows XP, and haven't always had this trouble. Just recently. And I am not sure what I may have installed or uninstalled to have caused this error.

Any suggestions would be very much appreciated!
