thank you for the detailed response. ill try to gather this info soon.

i can say i use AHK (auto hot key) on all pcs. but scripts are only running per game. this one i dont have any running. maybe just having the AHK app installed could cause this. but its really a common app and i think others would have probs too. ill uninstall and see.

and i have used SharpKeys rebinder before. it changes keys in registry. but i dont use it on this pc and have the prob on this one.

Gateway KB-0532 is the keyboard im on now
ill get the other keyboard models when i can.

keycodes3 gives this info:
volume down key
OnKeyDown, Key code=174, Control keys=, Key name ..........Unassigned
OnKeyup, Key code=174, Control keys=, Key name ..........Unassigned

mute key
OnKeyDown, Key code=173, Control keys=, Key name ..........Unassigned
OnKeyup, Key code=173, Control keys=, Key name ..........Unassigned

ScanCode gives this:
volume down key
19791873

mute key
18874369
