Hi, everyone as you will see i'm very new here and i would like to thank any one that helps contribute to the problem at hand here. So long story short i bought a "EVGA Z97 Classified motherboard" However it's actually a Z87 classified.. It's been flashed with the z97 classified bios hence at first i thought it was legit and so on. But i had driver problems and could not sli. The other two bios don't boot so how do i get the z87 classified bios back on. And i have done ctmos and i have take the battery out for 8 hours and tried again. Any help would be great! Thanks again.
