    I recently started having problems with my comp and normally i would format but i have been too busy and stuff to do all that and i need a fix for my problem

    the problem is after a while my svchost.exe screws up and i have to close it, which then causes my sound driver to disappear..... and my keyboard shortcuts not to work at all ( media keys). I think the cause of this could of been an updated version of directx 9 feb, i am not sure but.

    any idea what exlactly svchost.exe is or what my problem may be would be appreciated thanks

    could any of them be hiding unwanted programs?

    eg how do you work out what each one is a shell for

    actually a search only yielded 3 threads that even mention svchost, and none of them have anything to do with a driver based failure.

    And im guessing he has probably tried google too...
    maybe alecstar can help, hes always good with these software/driver based problems

    The guys above found the definitions from the horses' mouth on HOW svchost.exe works...

    VERY "SORT OF" like how you can see NTVDM.EXE work in Taskmgr.exe, when it runs DOS/Win16 programs really!

    NTVDM.EXE acts as 16-bit program's 'broker' more-or-less... running them in ITS memory spaces as subordinate processes for CERTAIN w/ Win16 by default (unless you make them run in separate ones) & DOS ones run in their OWN spaces - still, this is what controls them in either case!

    A tool by Sysinternals (procexp.exe/"process explorer") can give you THAT kind of picture (how taskmgr.exe can show ntvdm.exe 16 bit process broker & showing its child processes) on services processes (services.exe, svchost.exe, etc.) & 'break-out' their subordinate services they run, & control them as well, like how taskmgr.exe can do...

    A 'better taskmgr.exe' in some ways really!

    APK

    P.S.=> Barring that, which is a GUI program?

    I believe that:

    tasklist.exe /SERVICES

    Can do the same for services, albeit in DOS console/tty terminal screen mode... tasklist /? gets you ALL of its commandline options, if I am incorrect above though!

    In a hurry now, have to go, but hope this helps! apk

    Yes i have tried searching for it =P, normally i find the results a lot faster then waiting for someone to post a working solution, but then theres times when it takes too long and i just post a threat.

    I have tried tasklist.exe in cmd, i am not sure what i am really doing with it but, and i got no idea how to work the filters.... (I wasn't really around during the dos days).

    If it helps I got an nforce chipset, and i am using the integrated sound card, when the svchost.exe dies, I cant access my nvidia mixer (thing in bottom right corner).

    Then, hit Microsoft's SystemInternals site, & download PROCESS EXPLORER...

    http://www.microsoft.com/technet/sysinternals/default.mspx

    Look in the PROCESSES section, you will find it there.

    It will do the job for you, GUI/graphically easy... & it has a LOT more options for control than does taskmgr.exe, & also far more than the tasklist.exe command does (I mentioned that so you had something CLOSE @ HAND/native to the OS, that you could use immediately is all).

    * GOOD LUCK & you now have the tools for the job!

    APK

    P.S.=>
    This sounds like Windows Audio service is 'dying' on you almost... check that via services.msc, & also look @ your eventlogs in EventViewer for err messages, they ARE your pal, via using -> %windir%\system32\eventvwr.msc... apk

    Yeah your right my Windows Audio service is dying, I worked a way to get it working again without restarting and thats by going into services by admin tools and restarting it there.

    I figured as much... good, (well not really for you in your case) you now know what is what over there & @ least can work on it now, hopefully.

    That'll do it - services.msc is a direct way to that, because I am assuming @ least, that you 'attacked the problem' by messing w/ that service, there.

    GOOD LUCK - hope it does not keep happening & all that.

    APK

    P.S.=> Services HAVE options for when they fail, & I believe that attempting to restart themselves when they fail IS one of them... & if they fail more than X times, you can make a program run so you can restart them, or whatever (take a look around inside this service, in its properties, you'll see what I mean - right now though? I NEED COFFEE!!! It's "mornin'-tyme" & my brain's 'consciousness service' isn't working fully lol...) apk

    Hey sorry to hear, my solution was format n reinstall windows :(
    I was tweaking at it for ages and kinda gave up, even with alec's help.
    I know a quick fix but it gets annoying after a while.
    here it is anyways

    when the problem occurs go to
    control panel>admin tools>services
    find windows audio, and restart\start it.

    this however doesnt fix any other problems it may have caused, like my media keys on my keyboard and etc. (basically whatever else associates with the svchost.exe file)

    Get me your EVENT VIEWER failure messages for this service "conking out" on you... it MAY help!

    :)

    APK

    P.S.=> We "zero'd-in" on the fact that it IS your "Windows Audio Service" dying on you above via the methods I outlined, now...? Let's try to find out WHY... apk

    Don't thank me just yet, until we figure this out, if possible, but we know @ least that your Audio Service is getting its butt kicked by something @ this point is all...

    I need messages regarding why your Audio service is dead specificallly... or, svchost.exe even (taskmgr.exe can help), at the moment your sound dies, or near to it... then, in the eventlog you look for messages about that timestamped the same, or VERY NEAR to it.

    AND REMEMBER: Process Explorer from above? It's BETTER than taskmgr.exe in this case, because it can show you WHICH service is dying, when, & LARGELY, why.

    Catching this in event logs via eventvwr.msc, is tough... timing & possibly TONS of messages of the "ERROR/FAILURE" type to sift thru... but, it's STILL a good tool for this type of analysis, too.

    Don't jump the gun on this yet, doing stuff like that knockout & reinstall of network card drivers, as it may not be the cause here!

    (That is, unless there is somekind of interrupt interference between your NIC & your soundcard, DMA-interrupts related stuff, & resources on them can sometimes be changed - I haven't seen that happen in YEARS, not since the DOS days, w/ NICS & soundcards, but it might be happening here, but iirc, PCI-interrupts are NOT quite the same, & not limited to 15 IRQ's lines to the CPU, etc.)...

    See - I suspect it is NOT really this Netapi32.dll message you're showing - check the other events near that one, time-wise especially... & look for one related to services stalling.

    Thanks, & sorry for the inconvenience...
