I have Windows XP. When I turn the computer on the Dell logo comes up and then the screen goes to black with a white cursor flashing. It will stay for hours. I have defraged, run scandisk and nothing changes. I have also tried starting holding in F-1,2,3 and it still does not work. There is a message that says there is a 'keyboard error'. I also tried alt,ctrl,delete and nothing. What can I do? Ralph PCBUILD maintains hundreds of useful files for download visit our download web page at: http://freepctech.com/downloads.shtml
