Exiting a game and it errors HELP!!

[No Me]

Hey guys, every time i exit a game. well mostly every time. (90%) it gives me a blue screen with this error saying pretty much this
Driver_IRQL_not_less_or_equal
Alcxwm.sys

I am wondering, what is it conflicting with, I have basicly the same video card and drivers my friend does, only difference is that i have a silurio and he has a compaq consumer GeForce 2 MX 400. His doesn't do it. I just recently got a new mobo, cpu, ram and video card. and formated and everything. Games load and play fine, its just when I exit them, I get that error.. Any ideas??
I have a:
MSI K7T266 Pro 2
AMD XP 1800+
256 PC-2100 DDR memory
Silurio GeForce 2 MX 400

heres a question...Have you looked for alcwxm.sys on your harddrive and looked at the properties to see which piece of hardware that belongs too? it could be a sound card problem or a nic problem and not a vid problem

You might want to trace that sys file back, then update the drivers for that piece of ahrdware, or try moving it to a different slot on your mobo..I can tell you right now that doesn't seem to be a nvidia driver file at all so i'm kinda edging towards it being your sound board thats the prob
