My 13 year-old son is taking computers in school and decided to experiment on my Inspiron 8100 (they will have to take apart and put back together a computer as part of the final exam). Unfortunately, something didn't work out and when I press the start button, the green lights light up for about 30 seconds and then the thing just dies. Nothing happens on the screen. The unit is 4 years old and was working reaonably well up to now.
Does anyone have any suggestions as to what to do?
