i have not ruled out the bios chip on the mobo because, the mobo i switched with was the same motherboard, one that i had from the start of this build, and bricked it when updating the bios, so i used the same bios that was in the 2nd mobo to see if it was the motherboard. Wasted Efforts...

Have you tried simply RMAing the board? Do you have another AMD chip to check it?

dont have another amd chip... and the board is good... with the blinking light... all the research ive done says its not too bad of a problem... how my problem is different to all the rest is i cant get into the bios... as soon as i hit the power button, i get the blank screen with blinking underscore... im going to college for High Performance Computing... and this has me abit stumped...

Didn't notice this before, if you swapped bios chips you probably ruined both boards unless they were exactly the same. And I mean down to the exact same model and version. That would explain the blank screen and no post because the bios isn't booting up. If it did it before, the board is probably dead. If you have no other chip to test in the board your only option is to RMA and get a replacement. I would anyways after trying to swap a bios.

haha, you are right... but... they are the same exact board... lol ikr
