Hi yassine78,

Please refrain from posting your personal or system information on open Forum.

I’d suggest that you follow the steps mentioned below

1. Switch off the computer.

2. Disconnect the power cable from the wall.

3. Press and hold down the power button for 15 seconds.

Then connect back all the peripherals and check if you are able to switch ON the system

If you are able to turn on the system. Please try to run diagnostics.

Please reply with your findings.

Thanks and Regards,

Did the BIOS update complete, or did it fail (or freeze, meaning you had to power the system off before receiving a "successful completion" message?

You have two options:

Contact a shop that can unsolder the BIOS chip, flash it externally and resolder it, or

Replace the mainboard with a new one.

If you can replace a board yourself, it's likely to cost about the same - $150-200 -- for either option.  If you have to pay to have a board replaced, sending the system off for a chip reflash will likely be the cheaper option - $150-200 vs. that plus another $100 or so to have the board replaced.

there's a solution to force boot or something like that to reset bios?

That only works in a very few cases - from the sound of it, your system is dead enough that there's no way to get it to recognize anything - meaning an external flash or board replacement is needed.
