i was wonderen if some 1 out there might have any other way or ideals ,thanks in advance alotUnless you are experienced with computers I would advise you not to flash your BIOS I assume that's what your trying to do.You could do unrepairable damage. If you MUST flash the BIOS take it to a reputable engineer who knows what they are doing. I am an engineer and have had so many units in where customers have done what you are trying to do.
If you are just trying to update the software that should not be a problem. Download the zip files into a folder and open them find the install files on each and  CLICK them and follow the instructions. Just make sure you have the right download for your model




Good LuckAre you sure you got the right update? To me f.52a suggests a fith gen BIOS. Seriously agree with mrrigga, take to a repair shop. One bad flash can render your mobo inopperable
