Maximus XI Hero (Wifi) Display Issues with EVGA 980 GTX

tom808
Level 7
At initial build of this system I encountered some issues getting the GPU to work. Last week, it seemed to stop working after I let the machine go into hibernation/sleep mode. Some jiggery pokery in the BIOS and Windows 10 and eventually the GPU was detected and started working again. However, upon hibernation/sleep two evenings ago, my GPU display stopped working again and I had to use the on-board VGA, again. While in Windows with 'Microsoft Basic Display Adpater' (I tried to load Legacy drivers) showing in Device Manager, (and some Windows update that happened yesterday), Windows suddenly recognised the GPU and installed it! It was no longer 'Hidden' in device manager. So, yesterday, the GPU was working fine, again. I was gaming all day.

Today, booting up the PC, with no changes, the GPU is not detected again. No display. Had to resort to VGA. I've had no luck getting the system to detect the GPU at boot. Things I've done:

- Updated the BIOS
- Cleared the CMOS, twice.
- Loaded Optimised Defaults (a few times)
- Enabled CSM in BIOS
- Set primary display mode to PCIE in BIOS (from Auto)
- Disabled Fast Boot
- Put the card in a different PCI slot - no difference
- Re-installed Windows
- Disabled on-board graphics and connected monitor and TV only to the GPU (this seemed to work last week when I was having similar issues at initial build, but not this time)

Everything else seems to be working just fine. I'm even able to play games through the VGA, but at lot lower settings. So I'm wondering, what problem does this motherboard have with my GTX 980?? GPU Post in BIOS doesn't recognise it at all but I think this only works for ASUS cards. How can I know if the motherboard is picking it up at all at the moment? The GPU is currently 'Hidden' in my Device Manager - does that mean it's connected?

All recommendations welcome.

Spec:

Maximus XI Hero 390z (wifi)
i9 9900K
EVGA gtx980 Classified
Corsair Vengenace RGB Pro 3200Mhz
Samsung Pro 256GB SSD

Thanks,

Tom.

I can't from information available, rule out PSU as possible cause, if that helps your thinking.

So...I invested in a new PSU. 850W Corsair. All working fine...except no card detected. Again, the card seems to be alive....green light on top indicates it's using 'normal' BIOS (as opposed to an OC bios)...the LEDS for the logo are lit, and the fans turn on at boot up...however, it is not detected...It's either the card or the board...or there's some incompatibility issue....

It was the board. I bought another board and everything's working fine. I tried another graphics card in the broken one and, again, no detection. The PCiE Express slot power management or something must be faulty.

Very interesting. I bought a new MB - maximus xi hero-wi-fi and an - rtx2060 strix - and I have the same problem. only that with me the card was NEVER recognized. in Windows always 'Microsoft Basic Display Adpater'. However, the card is not recognized in older mb rampage formula. So card as the cause. ordered a cheap pcie-3 card to test. Lets see what happens...

Ok, I've bought and installed a new CMOS battery (good idea). Still no card... I may need a new PSU. I'm going to buy one anyway, this one's over 10 years old, at least...could a 'weak' or 'old' PSU cause this intermittant detection of the card?
