Asus Maximus RoG VII Ranger Q-code A2 and no display

[hansigno]

Hi,

I've had this build for around 3 years now.

Yesterday I played PUBG when it froze at the loading screen. I had to hard-restart the PC, but when it turned on it failed the first time and crashed and then it turned on again but with no display. I checked the q-code and it says "A2" - how can I fix this?

I have already tried to: reseat the GPH and RAM, MOBO Battery, Clear CMOS, removed my boot disk (still get the same code)

I hope someone can help me!

RIG:

CPU: i5-4670K
RAM: 16GB HyperX Fury
MOBO: Asus Maximus RoG VII Ranger
PSU: Cooler Master G650M
GPU: EVGA GTX 780SC


#EDIT 1: It now shows A0 but still no display. Removing the card and using the MOBO VGA however, gives a display. Any tips?

Because you can use the PC with onboard iGPU, so the problem will be from either the GPU or PSU. First try the GPU in other pcie x16 slot, if you get same result, then test the GPU in other PC, also try other PSU. Then you will find which one has problem.

Or try the local PC shop or your friend(s) ask for help.

MERGED QUESTION
Question from hansigno : "nVidia cannot find compatible graphics hardware / gpu not detected / no display with gpu"

Hi guys,

I am in need of some serious help.

I've been having some different issues and I have tried to fix it for days without luck. It all began when I played PUBG and it froze and the loading screen. I had to shutdown my computer but when I powered my PC on again I got no display on my monitor. I have a ASUS mobo and it shows A0 which means everything is OK. However, I am able to get a display when I connect the DVI to the MOBO. When checking device manager it said the GPU was not connected, I therefor uninstalled the driver but now I can't install it again since it says I do not have compatible hardware. I have tried almost everything from resetting CMOS, Checking all connections to updating BIOS / downgrading BIOS and I have also reinstalled Windows without luck.

I really hope someone can help me as I really need my PC to do school and other work.

Thank you!

Not sure where my reply went when the threads got merged...

It may well be a failed GPU - if you cannot get a display "out" when connected to the GPU, it's most likely either the card failing/failed, or inadequate power.

I assume you're outside the warranty period? Max 3year warranty period on EVGA cards.

It may be the PSU - the G650M is "ok", but not great.

Options are:
1. Try the GPU in another, known working, adequately powered system
OR
2. Replace the PSU with a known working, quality unit.

Thanks for the reply.

I do not think it is the GPU as I have tried another GPU in the system getting the same issue. I also think it might have to do with the PSU as I have had past issues with it (asus power surge...). But could it also be that the PCIe lane is defect?

What card did you attempt to use to troubleshoot? If a much lower powered card doesn't work, the PSU may well be the culprit. If you used a card that had a similar or higher TDP, that doesn't really get you much further forward.

If you've had power surge warning at a BIOS level, the PSU may be failing - the motherboard is detecting a power surge and, if you're not experiencing it throughout the home (which would indicate an "actual" power surge), that's coming from the PSU.

Yes, it's entirely possible the motherboard is failing - with a "dead" PCIe slot being an early symptom.

I used a Palit GTX 960.

What I will do now is to try another PCIe lane and see if that is the case. Ill post a reply when I've tried it.
