Hi, My computer was sent to the shop to help get rid of a virus but ever since it came back things aren't working. For example: windows meida PLAYER, quicktime MEDIA player, yahoo games won't load, some other games including games I've downloaded since the computer came back from the shop. Here's the error when I tried to run the snes emulator that I just downloaded:

ZSNESW caused an exception c0000409H in module DSOUND.DLL at 0197:beb14fef.

I don't understand that but maybe someone here will. most of the error files i've recieved have involved missing or not working .dll files, but I have no idea what this means of what to do about it, thanks  No mention of your OS, so I can only guess. You can find out about ZSNESW at:

You mention some software, windows meida player, quicktime media player that won't open. Any error messages? Perhaps the icons no longer point to the executables.

The only info I could find out was that DirectX version could be out of date. Something to check out.

Hope this helps.  Thanks for replying. I'm using windows 98. I don't think its the emulator that's the problem because many programs have had similar problems. Yahoo games LOADS a blank white screen without an error message and windows media player shows this message:

(very similar to the zsnes error message)
Both SEEM to have something to do with the dsound.dll file. I ran a search for this file and found it in windows/system with hundreds of other .dll files.
