Hello, my windows XP system crashes with a BSOD everytime I try to change the sound volume, both from the icon in the icon tray and from the control panel, audio settings. The weird thing is that the sound is working: I can hear windows sounds been playing at startup and I can also hear sounds from DVD or CD playing. I simply cannot change or disable the volume: the system crashes with a BSOD and even if the option to restart in case of errors is not enabled, it restarts on that BSOD and I don't have the chance to write down anything. Event Viewer contains those information for the system error: BCOde 1000007f BCP1: 00000008 bcp2:80042000 BCP3:0000000 BCP4:0000000 OSVER:5_1_2600 SP:1_0 PRODUCT:256_1 I have updated already the sound card driver, no success; I have tried already to replace the sndvol32.dll file, no success. I have researched the newsgroups, no success. Sttached the last minidump file. Can anyone help, please? Regards, D.
