Hai Frnds,This is ashok here.I had a problem with my system,plz give me solution if any one knows..

I a using ASUS motherboard.previously it was working fine.Once i got the error as ntldr missing,after that i formated my system and after that its working fine and recently i am facing with another problem ie., while i was using my system suddenly the led light stops blinking and the monitor gives me a different screen like distilated screen.Once if i restart the system i can get the normal screen and after 5 or 10min the same problem repeats again and again.what could be the problem...Its frustating me alotpothireddyashok04@gmail.com
