Hi,
Here are some troubleshooting steps that may help.
- Start by connecting an external monitor onto your laptop and observe if the same problem will persist on it.
- If the display will come up on the external monitor but not on the built in display that could mean that the built in monitor is acting up already.
- But if the same problem will happen on the external monitor, proceed with reseating the RAM's.
- Remove all the RAM's off for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, do try disabling all the startup items from Task Manager.
- Lastly, reinstall Windows and see if the same problem will persist after.
