Hi I have a laptop HP Pavilion dv4-2045dx recently three months ago and turn it does the audio sometimes and sometimes not, does not operate any programs that use sound hung like itunes and also the web sites as YouTube, to restart the sound comes back. Also now I am observing that my monitor is flickering while starting the Windows. Do you guys think that DV4-2045dx screen issue possibly? I am not having much idea about the screens.!! I restored the system but still the problem persists. So please help me soon as possible.!!
