I am new to orcad,using it from last 1 month.
Till now I had designed boards for thru-holes components only,but now i had to design a 4-layer board(2-routing and 2-plane(PWR and GND)) and it consists of surface mount components also.....and everything if fine till i came to the part of routing,the orcad is unable to autoroute the board 100% and i am just a beginner,so cant go for manual routing.

What should i do??
CAN someone help me with general solutions and defaults used in doing so.
 

As a beginner you should ONLY be routing it manually.

There is way much more involved in autorouting than simply hitting GO.

If Orcad cannot autoroute it 100% then what are you expecting?

You will have to manualy route it.

I suggest you consider starting again, moving some components so it can be routed 100% and manualy routing the important parts before autorouting.
 

Autorouting is not a good name, at best it should be interactive routing.
PCB design is a disipline that requires skills and knowledge in a lot of fields, that has to be learned, some of us on this site have over 20 years of learning PCB design.
I know that it is considered by some that anyone can do just by pressing the buttons, but it isn't.
Start your education with this lot:
