I have a Dell Latitude D600 running on Windows XP. I try to turn on my computer and either 4 things happen. 1. I turn it on and the caps lock light blinks and then it turns off. 2. I turn it on and then it freezes while it shows the DELL thing. 3. I turn it on and then it says that the memory has changed and can't turn on for the safety of my computer. 4. It loads, but then freezes and is worthless. I have tried to ake out the battery, and unplkug it to see if that would help and it did number 4. Please help and be descriptive, I'm only 13.
