Hardware Issue with Major/minor code 3.3

Question

Hello  I am Paras Sharma Owner Of  I am getting 3 long/3 short tones on Boot.  'The embedded controller has timed out waiting for BIOS to return from graphics initialization.'   I went to update some of the software from OptiPlex 3080 Micro Software and the drivers page. I downloaded about 8 different updates then started to install them. I have done this many times over the years.  1st I updated BIOS then rebooted, no issue.  Then I updated 2 or 3 others, I can not remember which ones (and I have not tried to recover the files from the drive) but I think one was Scalar Firmware Update another with the Video or Sound.  (During one of the reboots  I did see sometime about the ME?? - it could have been after the BIOS not sure )  Shortly thereafter during the process of installing Windows Defender popped up and said there was a serious threat if you want to reboot.  I choose Yes.  It rebooted and that was it.  I have a few questions: Is this motherboard toast? If not, what process can I use to fix it? I am furious with Dell.  Why am I getting a windows defender issue with something I download from them? Should we expect some level of support for a product that is out of warranty?  Isn't it the more environmental way of thinking?  I have kids and during the process I was not fully focused on the computer.  My 8 year old daughter felt so bad/ she felt It was her fault.  I calmly assured her that it was not her fault it was Dell's fault.
