hey, dude u were right i checked that whether there is a video card installed or not. and yes it was not installed. but i don't know that which one is my card. actually i also run the direct x window in which there was problem,i.e. that my computer is using another graphics card and there is no 3D acceleration active.
according to u i installed GPU-Z but it sayys that unknown graphic card.
GPU-Z would have detected an integrated card. If you have a card installed and you are running it without the drivers it will not recognize it since it is running of the win basic VGA driver. Where do you have your monitor cable hooked up? If you go into device manager under graphics adapters is there any thing with problems?
THnX dude u really helped me well thanks for ur support now my card is running properly
im now so happy....................................... problem solved.
Bye and THNX once again now iwill be able to play all my games.
