When I turn on my laptop HP pavilion windows 7 it starts but then a blank screen without starting

[Zaafir]

When I turn my laptop on, it starts and shows display but then windows does not start and there is a constant blank screen with a dim light. What is the problem? Is this the issue related to windows??

@Zaafir Here's what you need to do, to identify the issue and resolve it accordingly:

• check if it works fine on an alternate/external monitor.
  • If it works fine on an alternate screen, please Perform a hard reset, Attempt a BIOS recovery  and then, Run the System Diagnostics tests.
