Inspiron 3670, does not have bluetooth?
Can not enable Bluetooth in BIOS, its grayed out. You can restore BIOS settings which checks the box but is still grayed out. After exiting BIOS it reverts back to disabled (not checked) Tried different cards, drivers, CMOS, removing battery/memory modules, cussing an beating with no positive outcome. WIFI works on all cards. Is there anyway to reset BIOS/Board to factory.

Did you check Device Manager? See if Bluetooth is listed there. It might need a driver update or reveal a problem. Don't make changes in bios on today's computers. It is simpler now with Windows 10. Settings are changed in Windows.
First thing to do is plug in a Bluetooth device.

All of the above. clean installs maybe 8-9 times. Even hot plugging it. The only thing is registry. But they said its not going to be that, but policy's, fresh installs, cards, drivers, legacy drivers, pulling memory, clearing cmos, removing battery.. The only thing is from set up of the mobo at the time. It gave options in the very begin to enable or disable Bluetooth an that once these were set the option could not change. I know for a fact it was enabled. All I can remember at this time was anther option for hard drive an something to do with china it said. An mobo was reman. as probably like the other being shipped as well.

Windows 10?
If you search for Bluetooth in Win 10, does the BT settings screen show that BT is enabled?
Did you just try to pair a BT device?
Open services.msc from Start>Run in Win 10. Look for Bluetooth Support Service on the list. Make sure it's Startup Type is set to Automatic and that it actually starts when you click the button, if it's not already started. Do NOT change anything else in services.msc.
Then open Task Schedular from Start>Run. Expand the folders in the left pane and in the Windows folder, click Bluetooth. In right pane make sure UninstallDeviceTask is DISabled, if you have that task listed. And if any other BT task is listed, make sure it's enabled.
Reboot and test BT again...

Have you tried repairing Windows or clean installing it? (Back up personal files on external media first, and make sure you have product keys for any apps you installed.)
And it would been helpful to tell us Dell is sending a new motherboard in your OP!
EDIT: And did you check Task Scheduler to make sure that the BT UninstallDeviceTask is disabled?

says the service can not be started, either because its disabled or has no enabled devices associated with it. We have tried everything dell has been working on it for a month an they cant figure it out. They say they never seen this before. They have sent new cards 2 Qualcomm, an Intel 9560 then they sent another mobo which didn't boot so waiting on another. But from the sounds of it they have know clue.
