[francosalda]

Hi i  bought an Asus sabertooth z97 mark 2 motherboard and i have problems with it. first i cant enter the bios , when i enter  the PC get freezed ,( also i can't install windows because the difficult way to install that it had, but lets leave that problem for later) ...

 

i tried to update de bios ( it has the oldest one) , i donwloaded the bios from ASus website and i renamed it , then i plugged the USB ( fat32) into the Bios Flashback usb port  and pushed the Bios Button ( behind the cpu) for 3 seconds and it started lighting up but then it got freezed)

i don´t know what to do , now it doesn enter to the Bios display.... sometimes yes ... sometimes nothing.... and when i can enter to the bios it get freezed after some seconds..

 

i need help to update the bios , i think that it will be a good start to solve all this

 

my setup : intel i7 4790k , 8 GB 1866 mhz of ram ,  PCU sentey 750W, 1 TB hard disk

OK the updating bios problem was solved ( i had to make a low level format to the pendrive before copying the bios file) , now how can i installa the OS that i have on my pendrive? (win 8.1) it keeps giving me a blue screen

its impossible to install windows , i think the problem is the Mobo , every time i try to install ( xp,7,8.1) (from cd/dvd,pendrive) i get a BLUE SCREEN... i have secure boot disabled and CMS:auto
