Sometimes it turns on, sometimes not.

I made an upgrade and installed two new video cards on my PC , but now the image appears only occasionally , when it doesnt show up I have to keep restarting until it does.

Also when it does not appear there are some things that can happen :

- Windows Goes straight into safe mode and swhen the loading bar finally goes off, no image show of and you can hear the log in sound from windows.
- Windows displays that screen asking if you want to start in safe mode .
- Or nothing appears ( The motherboard LED shows b2 code and freezes there, I have a Maximus 7 formula ) .

 

When I finally get into the computer , everything is normal, and the cards work 100 % . (I think, BF4 runs at 4K, HIGH and MEDIUM 80-100 FPS)

 

Anyone knows what could be happening here?

I think B2 is bad BIOS, at least on my ASRock which is AMI BIOS based, which I assume your ASUS also uses AMI BIOS.

What would be the problem with the BIOS?

idk, maybe the flash chip on your card is bad or the bios flash is bad. i'd test the cards individually and the one that causes problems i would rma, fixing it yourself could just cause further damage and void the warranty.

I made some quick tests and they were inclonclusives:

I am going to call one card 1 and the other 2:

1- Only TOP(1) card, didnt turn on at first, and I didnt try restarted.

2- Only TOP(2) card, didnt turn on at first, after I restarted, it worked.

3- Both cards with TOP(2) BOTTOM(1), didnt turn on at first, after I restarted, it worked.

 

With this results, it may be the 1 GPU or windows problem. I will run some more hardware tests later when I have more time.

I formatted my PC to see if the problem stops, and it did. But now I am having some micro stutter issues, I have to pictures to ilustrate that: (In both of them, I am just moving one window around, with another behind it.
