XPS 8700, BIOS update failed, no boot into BIOS/Windows

Upgrading BIOS on my XPS 8700 From A9 to I believe A13? BIOS upgrade failed. System still powers on, NO BEEPS, CPU heatsink fan spins up, case fans spin up, I hear HD's engage. (I still have the old 7200 RPM s Steady Amber light on Motherboard, but display never comes on. Was hooked to GTX1050ti video card before and was working fine. After the BIOS snafu, no display. CMOS Clear, Jumper Short didnt work. Also pulled the 1050ti and tried with the onboard video just to see. Same outcome. I'm really stumped on this one.  Any ideas?  Bad motherboard? Thanks in advance.

A corrupted/failed BIOS update on many Dell's means the motherboard must be replaced.

Here is the Dell policy on this:

Dell Policy, BIOS breaks motherboard CMOS

 

In warranty customers

If a Dell Support representative directs you to update the BIOS, and it broke the motherboard CMOS, Dell will replace the motherboard.
Stipulations =
* The service itself could be either onsite service or Return to Dell Depot, depending on which warranty you purchased

If you updated the BIOS without any direction from a Dell Support representative, and it broke the motherboard CMOS, Dell will do a one time only motherboard replacement.
Stipulations =
* The service itself could be either onsite service or Return to Dell Depot, depending on which warranty you purchased
* We will then ask you to not install any BIOS update unless you contact us first and have us guide you

Out of warranty customers

If a Dell Support representative directs you to update the BIOS, and it broke the motherboard CMOS, you are eligible for a one time only out of warranty motherboard replacement.
Stipulations =
* This is a one time only offering
* This is a parts only service. Dell will not send on onsite technician
* Dell will only have motherboards available for 5 years from the original system RTS (Ready To Ship) date. If you are past this 5 year period, you will need to purchase the motherboard from a 3rd party seller

If you updated the BIOS without any direction from Dell Support representative, and the BIOS update broke the motherboard CMOS, you have to buy the replacement motherboard either from Dell or a 3rd party seller.
