Here is my problem, I have installed valid XP Pro licenses on three separate devices. 1. Compaq NX9600 Laptop 2. Gateway Solo 9550 3. Dell Precision M70 All three were updated with SP3 and are running Office 2003. All three laptops, after working for a number of days, now will not boot into normal mode and show a black screen after the progress bar. The laptops will not except any commands and have to be powered down to restart. All three laptops will boot into safe mode. I have tried a selective boot thru msconfig with no success. Any ideas or suggestions?
