I have a Dell Inspiron 1521, the computer will turn on, and all the lights will flash, however nothing comes up on the screen. I have tried taking out the battery and holding down the power for 20+ seconds several times but that does not work, I have tried swapping out RAM sticks to see if that is an issue, I have tried taking a bright light to the screen to see if the inverter is shot, but there is no picture whatsoever. I fear that the Video card or motherboard may be bad, is there any further troubleshooting steps I can take to pin point the issue, or resolve it all together. Any help would be much appreciated.
Thank you
