Respected Admin:-i have dell inspiron 3420 laptop,when i switch on the laptop,there appears dell logo which then disappears and there comes black screen with cursor and nothing else.I tried various methods such as removing the battery,cable and then holding on the power button for 1 minute etc but this does not work.Anothe method that i tried was diagnostic test which some days back it shows some error"Fail PSA V4220 Error 2000:0333.Video-User provided no input for graphics test"but today when i am performing the same test it shows no error and displays a message "pass PSA V4220 ePSA extended test pass". so what might be the problem with my laptop.(please answer as quick as possible)
