Following an upgrade to this (my first MSI) board, I've installed an i7-10700K and my current GTX 1070 card. Other system specs are 32GB DDR4 3200 (2 x 16 in slots A2 & B2); 2 x M.2 NVMe and 2 x SSD (SATA slots 1 & 3). PSU is a Corsair RM550X (550w) and monitor is an MSI MAG341CQ. BIOS is 7C76v20, which is compatible (although not the latest ver.)

The issue I'm having is that I'm not getting any video output from the GTX1070 during BIOS or Windows 10 startup. The monitor switches between 'No Signal' and then thinks it's detected something but the screen is blank. After a minute or so, the Windows logon page sometimes (not always!) appears and the PC is perfectly fine afterwards. I've switched integrated graphics from IGD to PEG, but it makes no difference. I've cleared CMOS and re-flashed the BIOS (7C76v20) but again no difference. Also, sometimes the PC powers on but the screen stays blank and Windows never appears. At this point it seems the PC has become 'stuck' before Windows, since a single press of the power button turns the PC off instantly.

If I remove the GTX 1070 and use an HDMI cable into the onboard port, then I can access the BIOS fine, and everything behaves normally.

In terms of the GTX1070, this has been working fine in my old system (Gigabyte motherboard).

Any help would be appreciated!
Thanks

Try this NVIDIA DP Firmware updater for the graphics card, to see if the "no signal" disappears at least: https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/

Also, you should try the latest version of the BIOS. Yes, they're not mentioning anything relating to the graphics, but trust me, internally, those changelogs are WAY longer. They only list a couple big changes, but there can be as much as around 50 changes and fixes with a new BIOS version. Flash within the BIOS using M-Flash, not in Windows. You can also extract the other BIOS versions to an USB stick, so you can flash whichever version you want. But if the latest one works at least as good as the old one, i would stay on the latest.

No, it's a Gigabyte GeForce GTX 1070 G1 Gaming.

As much as I'd have liked to buy an RTX 3080 today, the option went from 'Notify Me' to 'Out of Stock' in the blink of an eye!

Thanks - I'll give this a try, although (and I forgot to mention this), I'm not using DisplayPort.. I'm using HDMI (monitor) to DVI (Video Card). Reason being, I have an Oculus Rift which needs the only HDMI port on the 1070.

Not too sure what to try next. I may end returning this and buying a different board.

Myself, i would try the route of a new graphics card, it's probably less effort 😅

That's a fair point - since I don't fancy ripping everything out to replace the motherboard... but I've just tried my ATI Radeon HD 5450 card from my HP Microserver, and have exactly the same issue, so I can only put the fault/bug down to the motherboard. I'm surprised this issue hasn't come up for anyone else though?

I know this is an MSI forum, but any suggestions on a replacement model? I generally use the PC for 'workstation' stuff and general PC stuff, but I also play Flight Simulator 2020 and X Plane 11 a lot too.

Go in to Bios and Disable you Intel GPU on the CPU I had to turn of mine on my NUC for the E-GPU to work correctly

Thanks for the suggest Alan, it's a good one and great to hear it worked for your system. Unfortunately I have the same issue regardless of the BIOS setting.

As it happens, I've swapped the motherboard for a Gigabyte Aorus Elite AC, and guess what... I have the same issue!! So, I can only put this down to a compatibility issue with the Gigabyte GTX 1070 G1 Gaming Rev. 1.0 graphics card and either the X490 chipset or the i7-10700K CPU. I've tried flashing the VBIOS with all available versions from Gigabyte, but no luck. I've now logged a ticket with Gigabyte support to see if they can suggest anything, but I think a new card might be the answer (perhaps an RTX 3070 if I can manage to get one!).

I'll continue to post any updates - just in case it helps anyone else in the same situation.

Cheers
