The problem sounds like a design flaw with the PC, and not anything wrong with the OS. Simply put, if software can destroy hardware, it's the hardwares fault.
Deal with dell, they're the ones at fault.
Now, I am little concerned. I was just about ready use windows 10 more. Now, I am thinking of totally removing it. See, I also have a dell that had its motherboard replaced do to an electrical surge. Windows 10 wasn't installed till way after that replacement with my multiple boot system. My dell system isn't the same model but it is still an all-in-one. If an operating system or driver could damage the motherboard, Windows 10 needs or the driver needs to be recalled as soon as possible.
Is your hard drive a ssd or hdd? Mine is an hdd which might be the difference.
Do you have access to the dell drivers cd that should of came with the computer? There is a way to possible re-flash the bios using the driver disk tools normally I don't recommend flashing the bios, I consider that the last resort. I am not sure how to do that, I only did it once. I can't remember what I did. Once, you get into the bios installed, reboot into the bios and disable secure boot. Reboot computer if it boots into windows 10 either roll back to previous operating system or disable/uninstall dell driver update tools and let windows update handle them. My experience for the limited time I used windows 10, is all in one dells that are upgrade to windows 10 do better with driver from windows update then from dell. Ironically, Dell provides the drivers to Microsoft to use with windows update.
Even if it may "look" as if the MB is damaged not a single OS install can actually kill it.If an operating system or driver could damage the motherboard, Windows 10 needs or the driver needs to be recalled as soon as possible.
No need to reflash a bios to return it to its default settings, remove the power cord, wait a couple of minutes, remove the cmos battery, wait a few minutes.
Remove/disconnect all peripherals, HDs, put back the cmos battery, power cord and the power up the machine and you then should be able to access the bios.
That's the first step to make sure there's no physical damage to the machine.
Having sais that, TS' particular MB seems to be troublesome from what you read about it. Doesn't mean it shouldn't be capable of running W10 though.
I'm not saying this is the same issue (it won't be), but as an example of the sort of things which can happen with hardware, there was an issue with one of the preview versions of Windows 10, where it could send a command to certain hard disks to put the disk in a mode which wouldn't boot.
The hardware wasn't damaged, but it had been sent into a mode which Windows couldn't it back get out of, without using specialist 3rd party tools to change the mode back.
See the Microsoft employee's response on this thread.
The reason I said re-flash the bios, was to restore the dell logo. I was using that as a very last resort when you having nothing else to lose. Like doing the CMOS reset first as you said. I think all-in-ones are a pain to remove the stand. That dell driver cd, has a special way to boot outside of bios or at least mine does.
One of the biggest problems with 10 is the automatic driver updates through Windows Update. Particularly as they are done invisibly in the background. Fix a problem, wait a bit, reboot, and your system is hosed again due to the problem driver having been re-installed.
Another problem is Fast Boot. Seems like a good idea, but it affects POST (power on self test) behavior. Problems may require clearing the CMOS, which is not always easy to do with a laptop or AIO like the 2710.
A good feature of Win 10 Pro is that it allows driver updates to be turned off.
