I have a Dell Inspiron 1525 running Vista that will not boot up. When I turn the computer on the fan runs but the screen stays black and nothing turns on. The battery light blinks amber, and the wifi catcher light blinks yellow then blue. I thought it was the DC power jack/USB board, so I bought and replaced it, but that didn't do anything. It still does the same thing. I couldn't find any diagnostic for the blinking lights (the keyboard lights do not light up). I tried re-seating the RAM and anything else I could think of, but nothing works. Does this mean my motherboard is fried? How can I tell if it is that, or something else? Any advice would be greatly appreciated, thanks.
