Hi Chris, thank you for replying.

I went step by step thru the list and there's no difference. Testing Dell Video chat - says there is no camera.

No camera is listed in Device Manager; also no 'New Hardware' message came up when Windows started. The USB ports are still not working.

When I go to "Add Device" in control panel, camera and scanner wizard, the only device listed as available is "xerox work center pro scanner" - something I never even  had!

Now what?

Thank you!

The devices that will not work on the monitor's usb ports WILL work in the front side ports of the CPU --

there is one bad usb port on the rear of the cpu (just tested it).
WHERE is the hardware profile of the system located? Is it sysinfo?

Is my monitor out-of-warranty (purchased 11/2008) ?

And you have tested another USB device on the Desktop PC USB ports to verify they are still working? If yes, it sounds like the monitor is defective.

Download the Auslogics System Information tool. I will need your monitor order number in a private message to check the warranty status.

oh - monitor ORDER number?  I'm really not sure if it was a separate order?

Would service tag on my 518 do it?

I've dl'd and running the sys info tool.

It says "no problem device"; however does not see any web cam.

Shows 10 usb ports... which I believe are the ones on front, back, top of the cpu.

Service tag is fine.

my monitor is doing the same thing as yours, shows xerox work center pro scanner - did Dell replace your monitor or was another fix involved?  

somehow I got lucky on this desktop, dell threw in 3 year on-site for a small amount of money - the $500 laptop I just purchased they wanted $332 for the extended warrently, I declined.

I got lucky - Dell actually replaced the graphics card last week - I missed that he didn't plugin all the cable correctly.

I do have re-curring problems w/ the monitor - I have 14m left on warranty period.

I am somewhat confused. How can you hold us responsible for the effects of a power outage? That is certainly not covered by our warranty. The power outage could have damaged the PC motherboard, video card, power supply, CPU, anything. I do not believe it is a reflection of our hardware quality. I think any PC manufacturer hardware could have issues with power outages.

Was the PC and monitor connected to a UPS or surge protector? If yes, those should have some kind of warranty for the items connected to them.

I  do not hold dell responsible for the power outage. The monitor was the only thing affected during the outage. I had been having intermittent problems before this. Sometimes the usb's didn't work, then they did.The webcam and mic tho worked okay up until that time.  I am having the same problems with the built-in card reader: sometimes it works, sometimes not. Same with 2 of the cpu usb hubs: 1 or 2 will often not work. 

it has been a shaky machine in the last 12 months - just like the one it replaced. Now that one is relegated to word-processing only - it's just slowly failing. each time it is used, more error messgaes, more BSOD occur, -- be nice to have a machine that will perform reliably, and without fail, for at least 4 years.  - i guess you just get what you pay for...
