thanks to everyone. few days back i bought doom 3. i know that i'm years behind. but i did not have good computer where i could play doom 3. it was from jurassic age. i installed it, everything went fine. suddenly from today morning keyboard stopped responding. i can not use arrow keys or any 'A', 'S', 'W' and etc keys. whenever i press them nothing happens. strangely 'esc' button, F1, F2......F9 all function buttons are working !!! keyboard is all right it is working perfectly in all other conditions. so after uninstalling i reinstalled it. even after reinstalling keyboard buttons are not working other than esc or F buttons. then i changed the keyboard with another one. but the problem persisted. what should i do now? reinstalling, changing keyboard didn't help.
please help me out. i do not have any other game on my desktop so that i can check that.
my specs: win xp sp2, intel core i7 920 processor, msi x58 motherboard, 3gb ddr3 ram, palit gtx 260 896mb graphics card, seagate 500gb 2 no.s
waiting for any suggestion & help. thank you once again.
