Thread: black screen, CAPI2 errors in Windows log caused by Zonealarm?

    Default black screen, CAPI2 errors in Windows log caused by Zonealarm?

    System: Packard Bell, Vista (fully updated), Zonealarm firewall, Avast antviirus.

    symptoms:
    -for a longer period (not sure how long) at startup after welcome screen comes a black screen for several seconds, but after that normal functioning.
    -in the last few weeks in some cases the system keeps on hanging in the black screen; the only way out then is ctrl+alt+del (to reboot).
    -sometimes after reboot it happens again, sometimes i get a 'normal' startup.
    -in windows log 'applications' i've found series of CAPI2 - 11 errors back to May 2009

    I found out that -in my case- the errors are related to Zonealarm; disabling the Zonealarm firewall results in errorfree booting.
    Instead I tried Windows Firewall, but this caused (many) other problems (failing internet connection), and gives very limited control over what happens 'behind your back'.
    I switched back to Zonealarm, tried all kinds of settings, but i can't get these CAPI2 errors to dissapear.
    QUESTION: best settings for Zonealarm? Is it possible to use it and NOT get CAPI2 errors?

    Another interesting link about this problem (but with quite complicated advises) is:

    Thanks very much for your reply!

    Sorry, I don't run Vista, but I did find a newer MS forum posting than the one the OP originally posted. Maybe it will provide some additional help:

    I'm running a homebuilt machine with win 7 64bit. ZA free. Avast. and not much else for software except the HP software that goes to my printer.

    My Capp12 issues were caused by 2 audio devices. I did not install any sound cards. My video card and my onboard sound were at odds. (Who knew!!) I was told at MS answers to disable one of them and VIOLA! no more CAPP 12 errors. May or may not be your problem. Good luck.

    Hope this helps.
