Hi again - I posted the other day telling about how a usb cable/palm pilot shorted out my mobo. It wasn't the psu, as first suspected. I replaced the mobo and rebuilt the system. I reloaded windows today and had no problem logging on, but when the windows cd was removed, I was unable to. During boot up I get the error message about having a boot disc failure. Now, I reformatted the virtual C drive but not the virtual D drive on the same hard drive - is this a problem? It doesn't seem as though there is a failure as I'm able to log on to windows with the cd in place. I changed the bios settings as needed, only choosing the hard disk as boot disc. Do I need to reformat the entire physical drive and reload windows again? Not sure where to go at this point. Thanks again for the help the other day, it was appreciated.
