My hp compaq nx7400 PC Notebook's screen got bliked after certain minutes again and again after i installed Mysql server 5.1. Anyone hava idea

It seems there is a conflict within that software and your notebook remove it and see if that fixes this issue. Not quite sure as to what your trying to explain. You can also do a rollback as well read up on the compatibility issues that you may face downloading this software to use in a Notebook PC. If you un-install the software and this fixes the issue make sure your downloading the correct version of this software or any software you wish to to use with your notebook. It is obvious to me that Notebook worked fine "Right" before you installed this software. John
