hi.. first of all I'm an Asian.. im really sorry for my english.. I have a keyboard that works perfectly fine when I'm typing.. this is sony vaio pcv rz24g.. but I'm having this problem whenever I play a game.. I have lots of game here on my PC.. when I'm playing nba live 2007, counter strike, spiderman 2, battlefield, my player will stop walking when I press 3-4 buttons at the same time.. E.g. playing nba live (baseline low camera view)when my player is running, I'm pressing the up button so it will run forward, but when I press up + left button, so that my player will run to north east.when I pressed this key, my player will run to north east but when press up button again, it will stop running.. I'm a gamer so this is really annoying for me.. please help me please... here's a link for a same problem (in case you don't understand my problem) http://www.pcguide.com/vb/showthread.php?t=64274
