A Positional deadlock - can you please suggest a continuation for white


I am a low rated player as you can see. In one of my last games, i faced a setup, as above. I don't know how to continue furthur, continuation which would give advantage to white.

These kinds of positions can be tough. I don't have time for a thorough analysis and I'd stand a good chance of being wrong anyway but here's some things to think about.
Your knights are better in this locked position than black's bishops and your bishop is strong because it's not being penned in by your own pawns. Breaking through usually involves the sacrifice of a pawn or piece. You could try doubling rooks on the "a" file and posting a knight, possibly protected by the other knight, on square c5. You could then push the c3 pawn to try break up black's pawns and invade with your rooks. You could also create a position called "Alekhine's Gun" which would be the rooks doubled on the "a" file backed up by the queen before you push the c3 pawn.
Anyway, gotta go. I'm sure others here can give you more, and probably better, advice.

Gomer_Pyle gives good advice, I think. Another couple of general points:
(1) Don't hurry! As Gomer_Pyle indicates, strengthen your position as much as you can, for example by placing rooks and queen on the a file, before taking more direct action like Nc5 and/or a pawn break.
(2) While manoeuvring your own pieces into their optimal positions, watch out for Black's possible resource sacrificing a piece on b4 for which, if you are not careful, Black might get 3 pawns (your b, c and d pawns) leaving Black with 3 connected passed pawns which will be difficult to deal with when they roll down the board.

Black can play N X P and if white replies with N X N then black plays B X N ch : followed by QX P and also attack on knight at a3 : so to avoid this , as Samareshc says NC5 is good : it prevents all of the messy complications and builds up an attack too .. C
It's a draw, but you have a chance to swindle the guy.
What you do is the following:
Play Nb1, Ke3, Nd2, Nb3. If he ever plays moves his knight, play Ndc5 immediately. You want to tade your knight for his bishop so you are hoping for Bxc5 bxc5. If you can get this accomplished you have a chance.
If he offers to trade rooks on the a-file, trade only your Queen rook, keep your KR on g1.
If all of this works, then you spring the trap by playing 1.Bxh5 gxh5 2. g6 fxg6 3.Rxg6! followed by 4.f5! with chances to win.
