builtin games are not playing

hi!

well i got a new WINDOWS 7 ULTIMATE 32 BIT but the problem im facing is, the builtin game like CHESS & all other games are not working.
althoug they are there and displayed but when i click any one of them, none of them is going to be played.
my second question is, i heared that all or most of the games are playable on WIN 7. i had a game BROTHERS IN ARMS, which is not going to be installed. so pleses help me regarding the matter.
thanks to all.

hi!

although there is a huge difference among MHZ & GHZ but a typing mistake can never be meat to real.
anyways! when try to go to start -> All programs -> games -> and then click on anyone of them (anyone except the one i've installed by myself like FARCRY 2)
the cursor become bussy for just a second & then nothing happen.

when i newly installed WINDOWS 7 ultimate 32bit, all the builtin games were woking properly but several days before i've just tried the net based game online and after that no one game is playing.

last night i installed FARCRY2 to check whether all the games are unable to be played or what but FARCRY2 is working prety well.

thats the whole story. if you need any further inquiry to get to the crucks, i'd appreciate.

thanks,
sohail.
