Every time I turn on my new Dell Inspiron Laptop running Windows Vista Ultimate, it beeps urgently and then displays a screen asking whether I wish to start Windows normally or run the Windows Memory Diagnostics Tool. If I choose start windows normally, the laptop starts and runs as it should. If I run the diagnostics tool, it runs - the computer restarts and a pop up comes up and says that the tool found no issues, then the computer runs as it should. The question is, why does this diagnostic tool wish to run upon every start-up and can this be avoided?
