Asus Maximus VII Ranger boot problem

[Skodmig]

Hey

I have a problem, which I cannot understand at all.

It goes like this: If the computer has been powered off or shut down, it will start up, but will not show anything on the screen. It stops at a Q-code 77.
Now, if I then take out my discreet GFX and use the onboard, then it will boot just fine and show no sign of problems.
Then I can power it off and put in my GFX and then it will boot fine not showing any problems at all.

I do no understand this problem. Its like, that the first time it boots, it does not like my GFX.

I have tried the following:
- Tested GFX in other computer, with other hardware - it works just fine here.
- Tested PSU - no problems
- Tested memory for faults - nothing there
- Tried other GFX in motherboard - does the same problem.

The specs for my computer are:

Intel I5 4690K
Asus Maximus VII Ranger (newest bios)
MSI GTX 970 Gaming
16 gb G.skill TridentX 2400 MHz
EVGA SuperNova G2 850W

Hi, Have you tested the second PCIe slot? Is it the same?

 

[Skodmig]

Yes, I have tried the second slot. It still does the same problem.

Then I suggest testing different power supply, if possible.

 

[Skodmig]

I have just done that. Still the same. It is really weird. I have never experienced this before.

Then either motherboard or CPU.

 

[Skodmig]

Im going to try another motherboard next week. Will see if that helps the problem. If not, then the CPU.

Please post back the result.

Okay, I have gotten the solution from someone on Asus Rog forums.

The solution to this is to use a DVI cable!!

That I did not think of at all. I have been using Displayport for the last 2-3 years and never in my life have I ever experienced such a weird problem.
But the computer booted just perfect and there seems to be no problem.

Glad you've solved it.
From your original post: " Tested GFX in other computer, with other hardware - it works just fine here.". I excluded a graphics card/port issue.

 

[Skodmig]

Well I really didn't thought about it could be the choice of port.

However, again, it's good you've fixed it and thank you for the follow-up.
