couldnot load opengl subsystem

i want to play MEDAL OF HONOR AND CALL OF DUTY2. BUT WHENEVER I RUN THIS GAME.....I GET AN ERROR MESSAGE AND IT SAYS. COULD NOT LOAD OPENGL_SYBSYSTEM. i HAVE AN INTEL 82810 GRAPHICS CHIPSET AND IS UPDATED. QUAKE III RUNS FINE IN MY COMPUTER. I DON'T KNOW WHAT'S THE PROBLEM. CAN ANY ONE OF YOU HELP ME SOLVE THISPROBLEM????????

I think we have been over this a few times. Th 810 is ancient history and MOH requires a decent card that probably support GL 1.4, while the 810 supports 1.1

thnx...i think i should buy a separate card.........but the problem is.......my motherboard doesnot have an AGP slot........now please don't tell me to buy a new mother board.........any soltions.........???

You could try a PCI card. I think there are some Geforce FX cards, but they are rare.
All Geforce FX and up and all Radeon 9500 and up support GL 2.0 to a good extent.
