Buzzing on audio output and loss of mouse/keyboard:can't shut down

Suddenly after starting the computer and going online there was a loud buzz on my stereo output. The output goes from my optical audio. This has never happened before. I flipped the receiver to radio and it's fine. Typing on my backup computer now. The sound from this computer to a different input on the same receiver is fine.

The mouse and keyboard are fine here too. But none of my mice or keyboards work on my main computer. I have a wired mouse and keyboard bridging the two computers with a KVM so they can share the same screen too. On the main computer I also have a couple of mice and a keyboard attached wirelessly. This setup has been fine for a long time. Years.

But with the mouse and keyboard unresponsive (I've unplugged all but the wired one), there's no way to shut it down safely.

Can someone provide a plan to diagnose the problem or tell me how you solved a similar problem please?

First up is the machine listed in system specs the problem machine? Also have you tried other mice or keyboards wired or not on the problem machine.
Even if you can get at least a keyboard to work you can safely shut down using that.

Now the set up I do have a problem imagining it in my minds eye it sounds quite complicated. having said that if it has gone for years like that then maybe you have some serious hardware problems with either the plug in devices, the machine components or both.

Now I have Googled KVM (never head of that abbreviation and never used one) and find it is a piece of equipment too that could be going south?

I wasn't able to get any mouse or keyboard to work. They are all listed in device manager and all working properly according to Windows. I had to do a hard shut down, restart and start in safe mode. I restored it to the point before I installed Quicktime and everything's been fine since. Quicktime and Skype are two programs that, for some reason, never fail to really cause problems. Odd. I appreciate your response and concern.

Well seems like they do conflict somewhere down the track and I really can't think of any quick and easy fix. I suppose it cold even have something t do with your security too - if it thinks something untoward is going on?? Possible as some do not like certain programs like the ones you mention.

My guess is the real culprit is the interaction with an old version of Nero, not compatible but I LOVE the photosnap viewer and I ain't gonna shell out big money for the newer Nero just for the photo viewer. I love Easy CD-DA extractor so I don't need no Nero for that! Anyway, that's my best guess. Thanks again for your answer and your concern!

Thanks, buddy. For a confusion therapist, you're very kind. The hunt starts to replace the Nero today. I like the way it scans folders but you never know, there might be something as good out there. I'm starting with Picassa today... I really just want a viewer, not an editor but they all come packaged that way now. Someone at Windows Seven Forums recommended it. A lot of people loved Irfanview but I hated the way it operates. Thanks again.

Just looking for a viewer, no editing at all. Picassa works in slideshow mode and double click mode though not as clear as Nero, which I uninstalled with a lot of other programs I don't use. Saved a TON of space. Now I realize I have other out of date programs. Ayay!!! The buying crying game never ends.
