First make sure all the fans are working and the heat sink is properly attached to the CPU. While it's running make a boot floppy, as you may need it. To do that got to Settings, Control panel, Add/Remove programs and choose the tab for making the floppy. The Windows installation files are in Windows/Options/Install in most ME installations. You can use the files to do a fresh install if need be, by putting them on a CD and starting the setup process with the repair floppy. To do a fresh install you should format the disk, preferable removing the old partition and putting a new one on and formatting it. You need to have the product key to do the fresh install.
