I've been having a BSOD issue that is always related to kmixer.sys. I have never really been able to find any conclusive evidence as to the source of the problem, I've replaced the RAM & the mobo, as well as throwing in a sound card, but to no avail. I never thought about the PSU being a problem, but after downloading SpeedFan, it came back with these results. +3.3V: 1.82V +5V: 5.67V +12V: 4.86V I'm still a pretty big noob with hardware and parts and such, and this certainly seems like a PSU that would need to be replaced. Would this be causing a BSOD though? I do notice that it occurs only when there is music/sound playing, this is just driving me crazy.
