I have an Dell Inspiron 2600 laptop. When I boot up the laptop I get the black screen with the highlighted Start Windows Normally. I am unable to get past this screen as it continually reboots into this screen, nor can I scroll into the safe mode. I cannot even boot into setup. It seems like all my keys, except the enter key, are not responsive. I am running Win Xp SP2, 640MB ram. All was right on Friday, now today this happens. Any thoughts? Many thanks!
