Our dear friend Raju just got a brand new assembled PC. It's 
   a P-III running at 800 MHz with 128 MB ram & 20 GB hard disk!!!! 
   His parents after  hearing all the hype about the need
   of a computer  decided to buy him this PC as they thought it's going
   to help him a lot  in gaining knowledge and in  studies. But our dear
   friend Raju has  something else on his mind, he was  completely
   facinated by some 3D games  he had seen on TV commercials and computer
   magazines , he just couldn't wait to get his hands on one of them,
   particularly QUAKE-III. He got cd from a friend. After a smooth
   installtion just having to click on the  'NEXT' button a few
   times, he had a QUAKE-III icon on his desktop. Our  friend holds his
   breath and clicks on the icon just waiting to be  transported to a
   whole new exiting world of 3D games and there is a 'sigh', no it's not
   a  sigh of relief, it is because he sees a message similar to :-
	 		searching for opengl.dll 			
			failed
			assuming 3dfx 
			searching for minigl.dll
			failed
			program halted.
   Does that sounds familiar, has it happened to you as well? Then you
   and  Raju have something in common, either you have been taken for a
   ride by  the assembler or while cutting corners to save a few bugs
   you missed out something important, something like your display card
   to be more specific. The quality of the graphics on the screen
   doesn't depend on your CPU or system RAM but  on the graphic
   processor and VRAM on the display card.Lets try to know a few things
   about graphics card.
