Normally when your PC beeps once on boot up, if you are getting a lot of beeps it could be faulty memory or your graphics card is not seated properly. Also when it is running, defragment the C drive, and go: Start/Run/msconfig/Startup and see what programs are running in the background. Too many progs. running at once in the system tray (bottom r/h screen) will slow down bootup. A lot of things can cause your problem, these are some of the ways I have solved similar probs. Have fun.
