8/16/2017 Yes, it is the Dell logo screen. There is a progress bar that so far shows about 50%, about 80%, and then goes away. So far I've rebooted about 10 times with no problems. Every time but one (so far) since I brought it home it has gone past the Dell logo screen to the Windows login screen in about 5 seconds. The one time it didn't, it went to the dot circle (like it was updating - although it hadn't been connected to the 'net) for a few seconds before going to the Windows login screen.
8/17/2017 I booted 5-6 times again this morning with no problems. I took it back to the office, reconnected everything, and when it wouldn't get past the logo screen after several minutes I shut it off. Thinking the problem was environmental I disconnected the network cable, but it still wouldn't boot. I reconnected the network cable, and disconnected the USB cables (ink jet and laser printer) and it booted fine. I repeated the boot just to make sure and it again booted fine. I reconnected the ink jet printer and it wouldn't boot. It seemed odd that this would be the problem, so I disconnected it again, but this time with no USB cables connected it still wouldn't boot. I shut down and tried again, but it still wouldn't boot.
