Title: GA-990FXA-UD3 no Post, no signal.
Post by: davijrh on June 09, 2013, 11:40:42 pm
Hi, first of all, sorry about my english (im from Venezuela), so is my first time building a PC. The system is 2 months old and I updated the bios (F10a) with a Sempron 145. Here are my specs:
•   CPU: AMD Fx-8350.
•   Motherboard: Gigabyte 990fxa-ud3 rev. 1.1
•   RAM: 16gb Corsair Vengeance
•   GPU: Gigabyte HD 7870
•   HD: 1T WD Black.
I was playing some games when my screen just froze, so i forced to restart with the power button. It enters in the bios screen but the windows took forever to boot and then froze again. When I restarted again the pc just didn’t start, all fans were on, but no bios screen, no post, not anything, just the black screen with no signal.
I read other articles with the same issue but none of them worked for me, I tried an external build (I use 1 stick of ram to test it) with no luck; I removed the battery and place a jumper to clear the bios, nothing worked. I tested the GPU, HD and RAM on my friend´s computer, all were good (couldn’t test the CPU because he have Intel).
I placed a speaker to hear the errors codes when I turned on, but it just didn’t beep. I removed the RAM but no beep either, also removed the CPU with no beeps. I think is bios problem, also the bios version F10a is beta. Thanks! for taking your time to read my problem.

Did you revert your bios using the back up bios chip. I think you hit f9 when starting to overwrite new bios with the back up bios. Another option is to download the bios you were using and reflash it.
