|We ARE giving you the best advice, a bad or failed BIOS update, whether done for the right reason or a misled reason typically means that you throw out the motherboard and purchase a new one. This is why we say never update a BIOS unless there is a really good reason for taking that chance. ONLY the manufacturer of the motherboard and possibly the system manufacturer can repair it, but probably would not. If you are very lucky, they may have a solution or if you can convince them that this happened following their instructions, they may be willing to replace the motherboard since that would take much less time than sending the system back for possible repair.|
If you purchased an extended warranty (not generally worth the money, but in this case, possibly), that may also be an option for repair/replacement.
Sorry if this is not what you would like to hear, but the stories on the internet of dead motherboards when a BIOS update fails are far more common than people who have found a solution and got it working again.
You have to be a little bit crazy to keep you from going insane.
