That was a good idea, but doesn't work. The plug in area is for a projector it looks like BUT when the desktop was booted, the lights on both the monitor and keyboard flashed, so they were recognized.

It's the cpu I guess. It has 6 months left on the extended warranty, but I can't think of where I keep those things.

I have 2 large binders of instruction manuals etc for everything I've bought... and many of those have the sales slips etc... but somehow they are out of place in the binders (can't imagine why this would be, as if the contractor would open the binder and take something??? )

Now I'm in a pain flare from moving the desktop and unplugging it and all... put my sacrum way out and it's impinging upon my right sciatic nerve. Working at not allowing the stress of the moment add to this.

Thanks for all the suggestions. I don't know why the sellers of the warranty don't have it in their files (not until you use it?) I'm too organized for this to happen, not be able to find the warranty info. Oh well. sigh.
