agar ap ka computer on ho aur display na day to us ki casing khol len:

1. Sab say paylay us ki sari RAM nikal len aur phir on krain. agar beep ki awaz aye to matlab ap ki kisi 1 RAM main problem hai.

2. Agar beep ki awaz nahi aie to matlab ap k Processor main Problem hain. Ab aap processor ko nikal len aur socket ko air say saf kr k dobara thik kr k laga den. agar dusri bar chal jaie to thik warna ap ko processor new lagana ho ga.

baaz dafa RAM aur Processor kisi waja say current sahi toor par pass nahi kr sakty is waja say dobara nikal kr laganay say wo phir say kam krnay lagtay hain.
