The number of beeps are 4 of which it reoccurs like after every 3-4 secs
. The beeps are also short...like a split second for each. However, i believe I have solved this problem from a thread on the forum. I opened up the computer, removed and re-inserted the ram; switching the ram across the ram slots and I realised that one of the Rams is bad. So I had a spare ram which I used to replace bad one and it came back on. So as of now, there are no problems. Thanks a lot.
