Computer guys I need help. Last night I was surfing various Porsche sites and all of a sudden the computer went blue and tried to reboot. The reboot was not working so I shut it off and thought I would try again today after work. But it only comes on to the point where it asks do you want to reboot useing safe mode,safe mode with communication, past known good startup or something like that. No matter which option I choose it tries to reboot but comes back to this same screen. I tried reinstalling Windows XP but no go. Last week I received a error message stating it couldn't perform a task because there was no memory. My HD is only about a 1/3 full. I have a Spyware software that I run almost daily that generally removes 10-15 objects each time. So did my HD crash? I'm not a computer weenie so talk to me like a 10 year old

. The computer is a 6 year old Dell Lattitude 600 that has been rock solid. What do I do?
