Windows XP BSOD when playing Left 4 Dead 2

[Swampwater]

I've recently been getting BSOD during gameplay whenever the next map tries to load. The game will play and then crash at random seemingly. I used WIndbg to get this information but don't know what it means:
I have also included some minidump files. Any more info would be great, I don't know what to do at this point.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: b6ce43b8, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000008, value 0 = read operation, 1 = write operation
Arg4: b6ce43b8, address which referenced memory

[Route44]

All five minidumps are the same 0xD1 errors and these are usually caused by faulty drivers.

All five dumps cite the same driver as the cause of your crashes: viahduaa.sys. This is a VIA High Definition Audio Driver and belongs to your onboard sound.

* Go to your motherboard's website, find your exact motherboard model and download the latest updated drivers.

may i suggest buying a better sound card if the new drivers fail?

Thanks for your reply route44. It hasn't crashed yet but sometimes it will run for a while without crashing.

may i suggest buying a better sound card if the new drivers fail?

What's wrong with the sound card I have? Other than the fact that I'm not entirely sure I downloaded the right sound card driver update for my computer, (ASUS P5KPL-CM) why would it not work?
