It mostly due to hardware problem and mainly form my view power supply accessing some hardware required more power.i would recommend you to have at least 450 watts of power above 500w if you have good graphics card.

A long beep refers to the memory modules just replace ram slot position also clean it well and try again if all that not work try then on another system and check that working.
