9.3 crappy

I loaded 9.3 up and install went well. I did the on line update part except the Nvidia ones. Rebooted did the you thing for the Nvidia. Rebooted fine. Diddled with a few personal setting such as screen saver and wallpaper. Shutdown and later fired up twice. Then I went to fire up and could only get a grey/blue screen that asks for log on and gives a console only. Its an x screen and does not allow for further options without knowledge on how to use the console a lot more than I do. I reinstalled and the same story! Any one got a clue what it's doing. I have reinstalled 9.2 and no probs. The screen did show an error about the floppy ( I did not write it down). There wasn't a disk in the floppy! Chris
