My system keeps booting hard (fan runs very fast with great noise) and nothing appears on my monitor. What’s the most likely cause, and how do I fix it?
if you have windows cd boot on it and choose repair or reinstal
Hello, that is the classic symptom of having dust bunnies living in your fans....Follow the guide provided above and you should be ok. Is it a desktop or a laptop? Is it an HP laptop? There were some HP laptop models where there were problems with the soldering in the video card coming loose and you would get no video as a result.
Does using another monitor help resolve the display issue? To troubleshoot the loud fans, I suggest you read How To Troubleshoot a Noisy Computer Fan.
