My laptop won't turn on

Hello,
I think I have the same problem. No matter how many times I push the start button, my laptop sounds like it's about to start and then shuts off. There is nothing on the monitor (the monitor does not even come on), but I can hear the fan. Were you able to figure out a solution to this problem? I appreciate any advice you can give...
