Game Crashes and flashing screens

[RVPERTVS]

Well, I´ve never experienced a single crash, though I have audio "hicups" now and then mostly during attacks, and sometimes the game seems like about to crash or freeze because of these, but it hasn´t yet. They appear about 1 time in every 6 or 7 attacks.

However I would like to fix these hicups but I don´t know a single thing about programing, codecs, drivers or whatever. Attached is my dxdiag print, I hope you Andy or someone could take a look at it and tell me if there´s something wrong or what can I do to improve my audio performance in order to fix the issue I´m talking about. I know I have the latest driver installed for my machine.

I would like to fix the issue without converting to WAV, because I know it must be a configuration issue only, because the game runs without this issue on my sisters, and I know my machine is better.

I tried turning off the mmswitch.ax thing but I got the "can´t find the module" window, meaning I don´t have that aplication.

Any help will be appreciated. Thanks in advance
