Secure boot is probably to blame, but I have no idea how to turn it off without a good BIOS. Flashing the BIOS should help, but you need access to F12 to do this from a USB stick.

Well now this is getting dumb.  I was able to get into the F5 diags, F12 wouldnt work. In there I chose to exit and got the Legacy boot menu and moved the USB to the top.  Saved, exit and then it only powers on to a blank screen with the 1-2-3 lit up.  I followed the proceedure to remove the battery and reset the bios and nada.  Nothing, still black screen.  I dont know what to do now.

I also removed all drives, all cards, and the USB drive and it still does the same thing.  Any ideas what I can do?  Thanks again.

Not sure if serious but is just my luck :). It was in legacy with secure boot turned off. I turned it on, at the hdd warning I pressed f5 and let the diags  run. Then when I exited it showed me the boot menu and I was able to move the usb drive to the top. Saved and then nada on the next boot. Pull everything and still nothing. Thanks again. It is a precision t7610

Sounds serious! Which Precision model are you using? Do you recall if your BIOS was in Legacy or in UEFI mode before this happened? Was secure boot on or off?

Is it a brick then? New Motherboard time?

As a last resort, read the following link.....it may (or may not) help. Dell does have a BIOS Recovery Tool for computers built after December 2015, but your T7610 is almost certainly earlier than that. Fingers crossed.

No, it doesn't work, unfortunately. I am looking for a new motherboard.  So ridiculous.

Just to update, I bought a refurbished motherboard and all is fine.  Definately the bios. Thanks to everyone that helped.

Change boot order. When you changed default it is possible that boot order changed as well. Default is hdd .

Assuming I understand the setup correctly.
