Thank you for your answers. Because the computer is new, the best thing is to exercise the warranty and/or contact the vendor or maker for warranty support. Even tho it would seems that the problem may not be hardware problem. If you see other PCs on the network, that would seem to indicate the machine is OK.
Not true.
Unfortunately, current design practice is to not include extensive diagnostics in consumer devices.
Your remedy is to use the warranty provisions. The makers have decided to keep users out of the troubleshooting process. They believe their on-line support is better than more user documentation and diagnostic tools.
So, test them. See if they know what this is. It just might be they have heard this before and know what to do about it.
Because this is a very new Dell, there is a very real possibility that there is one of these rare things that the engineers imagine would never happen. I have a vague hunch, but t rather than guessing, you should insist that Dell give burdensome support.
Contact hem with another PC you have, but you need the model, serial and Service Tag of the new Dell. You may want to call them on the 800 number, it you can.
