BIOS Dell optiplex 5050
Hello, after updating the bios of Dell optiplex 5050 <To protect you, your private information was removed from public view. All private data was saved to your private Case. DELL-Admin> it started to say at startup that the TPM module was not detected. It is also not available in the bios to be turned on or off. I have tried all sorts of options to fix the problem, but to no avail. According to AI, I need a specific BIOS update file that I can only get from you.

The computer is an OptiPlex 5050 Small Form Factor. Everything that is described on the site has been tried and is without result. Please help. I am looking for an official email to write directly to Dell but I can't find it.Alvy_das

Reboot, keep on Clicking F2, get in to BIOS settings and select TPM enabled, as well BIOS downgrade allowed, apply changes, reboot.>

Method 4: Updating Using a USB Flash Drive
This method is beneficial for users running Ubuntu or other Linux operating systems, or when Windows is not accessible. Additionally, you can use this method to update the BIOS directly from the One Time Boot Menu on compatible systems.
If downgraded (flashed) and (back) upgraded BIOS will give the same error, that'll be windows installation/ configuration / corruption issue
God forbid, during the (long) time BIOS flashing will take and you'll turn the computer off or unplug the lead etc- once/ IF BIOS does become corrupt- "lottery" to be able to replfash it (several layers to get to the core)
Fresh OS reinstall will be required, NOBODY via email or on a phone is going to be able to help you with that, as have several ("block"- layers) of safety on the actual chip on MoBo, so nobody could easily corrupt it remotely ONLY to learn, if BIOS is going to accept new OS install configuration.
Considering your M$ Office skills, I'd highly recommend taking it to a local shop or find a geek, that would do it for you, in your your presence.

You are welcome and thanks!
