I tried changing the num lock and the other fn settings but none of them seems to work. I tried changing the settings in the bios but that doesnt seem to work either unless theres a method that i missed. The keys doesnt work regardless if num lock is on or off.
Only thing that worked for me is that when I turn num lock on and hold a and z together, all the keys can be typed and keyboard works normally (aside from having to keep on holding the keys)
I also noticed that when i do this, the light for num lock switches (on to off or if it was off, it turns on).
This problem happens when i install both windows 7 and xp so it shouldn't be the os's problem.
If it helps, the usb keyboard that i plugged in is working fine.
