Z97 GAMING 9 AC - PCIE no longer detecting

[eclipse88]

Hi,

So I recently purchased a new system including the MSI Z97 GAMING 9 AC motherboard and MSI R9 280X GAMING G3 graphics card. After building the system I initially had problems with the graphics card not being detected. After some research I updated the bios to 1.4 and used the onboard graphics card to install windows 8.1, drivers etc. After windows, drivers etc were installed the graphics card still would not detect until I went into the bios and changed the PCIE to 2.0 (instead of auto). This then used the 280x instead of onboard and allowed me to install the graphics card drivers. I switched the PCIE to 3.0 after it was working.

Initially everything was working but the next morning I had the same issue again: only the onboard graphics card was being used. I switched back to PCIE 2.0 and it worked again. Until the next morning: the 280x is no longer being detected at all in any PCIE slots or in PCIE auto, 2.0 or 3.0. I have ruled out a graphics card issue as the 280x works in other pcs. I have tried another graphics card in this system and it does not seem to work either. In bios it just always says that the PCIE slots are 'empty'.

So I have tried the following:
1. Cleared CMOS.
2. Updated BIOS.
3. Updated Chipset, drivers etc.
4. Tested the Graphics Card in other computers.
5. Used a different graphics card in this system.
6. Tried PCIE 2.0, 3.0 and auto.
7. Completely reformated and started from scratch.

Any suggestions as to why the PCIE slots seem to have stopped detecting?

Hello,

Can you please provide your card's Serial Number here but also:

Use GPU-Z to make copy of vBIOS of the card (make the card work, even in PCIE2.0) and upload that copy into some free file hoster (make sure user don't have to register).

Thank you for your reply. Sorry for my delayed response. I need to add that I have had the system working for hours on end, playing games like Arma 2/3 perfectly so the graphics card seems to be working fine. The problem I have worked out seems to occur after I have shut down my computer and leave it turned off for awhile. Once turned back my monitor remains black, although fans and lights are all running and on, its like it forgets to use the graphics card (if that makes sense).

I kept having this problem no matter what I did so I have just organized to send it back where I bought it for testing.

It's completely up to you. A bit strange issue.

Report back if you got it solved or replaced

Was this issue ever solved as im seeing the same issue.

When I first booted the machine all was well however when I came to reboot my machine for the first time it no longer sees I have a GPU and so switched to the Intel onboard 4600.

At first I assumed the GPU had come lose or some BIOS setting needed changing. BIOS is set to use PEG (PCI-E Graphics card device) so i reseated the card and rebooted. This didn't work.

I reset the BIOS CMOS and that fixed the issue, my machine booted using the graphics card again however as soon I rebooted windows again it lost the card switching back to the onboard.

According to the BIOS the PCI-E slot is empty. I swapped the card out for an older ATI 7870 but had the same problem. PCI-E slot is empty unless I clear the CMOS (I made no changes in the BIOS).

At this point it sounds like some kind of software issue I have updated my BIOS to the latest version (1.5) but that hasn't fixed the issue. Whenever I shutdown or restart it will lose sight of my card unless I clear the CMOS or power down at the wall.
