Hello @gurukiran

 

Welcome to the HP Forums, and thanks for posting! :) 

 

I understand that your computer is turning on but only displaying a blank screen. I'd be happy to help with this!

 

Do you have an alternate monitor or small TV you could connect temporarily to isolate the cause of the issue? 

 

If you don't, or that doesn't work, follow these steps and let me know if you're able to get any hardware diagnostics. Turn the computer off. Then, immediately after pressing the power button to turn it back on, start tapping the F2 key on your keyboard. 

 

If you're able to access the hardware diagnostics, select System test then run the Extensive test and let me know the result.
