Yesterday I operated 2.75a but it shut off automatically again.I just clicked material button. I want to know whether some wrong is on 'user reference' setting?I checked all. Thanks.

Enabling all of the addons increases the probability that one or more could cause unexpected behavior.

I agree with DramaKing you do not need all of those add-on turned on unless you really need them and the ones which have the yellow triangle are usually not fully implemented or stable and that may be causing your instability issue personally I think 2.76a was more stable than 2.75 allot of bugs were resolved in the 2.76a release that seemed to plague 2.75

Also, I believe updating graphics card driver may alleviate the problem.

Thanks guys.I know may check all so that issue came out. And here are parameter when starting 2.75a.

OK I see one issue got to file user preferences got to the systems tab then look for sample rate and if yours has 44.1khz use the little arrows to change it to 48khz this was an issue with 2.75 that it would not change automatically to match your systems that is the first error you see in the second line of the screen shot you provided. Changing that and saving user preferences should resolve your errors again I still would recommend updating to 2.76a and also updating graphic drivers

Thank you so much indeed. But I find that every version of blender that I used,which it always showed 'fail to set xxxx ,got xxxx instead',which I cannot understand it is meaning.Does it say system is wrong? PC has not enough electrical energy?

The error I mentioned above I experienced the same issue at one time and updating graphic card drivers but had to manually make the change as I described in my previous post. It seemed that after version 2.76 this was no longer an issue that is why I recommend that you either make the change manually or update Blender to at least 2.76a also the Lux Render version you might be running might not be the right one for your system you may have to update the version and make sure it is installed in the right location.

That is referring to the audio sample rate. I've never had a problem with that error, though. Also, the pylux error could be the result of Blender being unable to locate the LuxRender executable. Seeing as you have all the included 3rd-party rendering addons enabled, the only surprising thing is that there aren't more errors.

Thanks so much.

Woah. I never saw anyone enable ALL of the addons. I think doing that could definitely cause some issues.
