Well this is my pc configuration:

Intel i7 920,8gb ddr3 ram,hdd-1 tb,os- windows 7 64 bit ultimate edition,nvidia 470gtx graphics card,motherboard-intel workstation WX58BP.

The problem is that the motherboard does not have any ps/2 ports and my keyboard has ps2/2 jack.I bought a ps2/2 to usb converter.Its a very strange problem.when i am typing its working fine but during gameplay when i am pressing two buttons at a time like walking and turning its not working.i changed my ps/2 converter but still the problem exists.i also checked my keyboard in other computer and found my keyboard is working perfectly fine.

can any one please help me?
