Occasional stuck on boot with white VGA QLED, black screen, no asus logo, no POST, nothing

Level 8

MB: ASUS ROG Strix Z790 f gaming wifi
CPU: Intel core I9 13900K
RAM:  G.SKILL DDR5 - 5600 2x16 GB
GPU: ASUS ROG Strix GeForce RTX 4070 Ti 12GB GDDR6X OC Edition, VBIOS V2
Screen: ASUS TUF Gaming VG27A
BIOS: default settings, version 2202

SSD: 2 WD-BLACK SN770 500 GB and 1 Samsung SSD 980 Pro 500 GB

GPU to screen connected using DisplayPort cable.

Sometimes, about 1/20 times, my computer stuck on boot with white VGA QLED on (either cold boot or by windows restart function). It has not come to display ASSU logo yet, all black screen and stuck so forever. If I restart by pressing power button to turn off, then turn on again, it will boot normally into Windows 11 and everything works fine, no crash, no issue (except explorer sometimes auto pop to front, which is a known issue of Windows 11 and has not been fixed so far), gaming is fine.

I reseated everything and the issue is still there. I have been waiting to update BIOS twice (about 1 year already) and nothing change.

So, not sure if anyone have the same issue and have solutions, so, I just post it here.

Currently, switching to use HDMI cable to see if the issue is still there. But I dont want to use HDMI because my screen is G-SYNC Compatible and only works via DisplayPort cable.

If the issue still occurs, it means it is not DisplayPort issue and I have to live with it till new BIOS or VBIOS update.

If the issue goes away, it means the issue so far is with DisplayPort, my GPU and my screen, I will change DP cable to check again.

Hi @hypergeome I'm glad to hear that you have resolved your issue. There are no GFX cards supporting PCIe GEN5 yet. The nVidia RTX 40 Series card (specially the newer BIOS) properly downgrades to GEN4 even if in the BIOS you set the GEN5 protocol as I can see on my system with Z790 DARK HERO (Intel) Board and RTX-4090 card.

Not every card is able to do this downgrade correctly so it is best to either set the PCI Slot to AUTO or GEN4 when there are issues.

The issue is, by default, it is "Auto" already. But it still stucks sometimes.

I then set Primmary Display explicitly to PEG slot as suggested by @Nate152 . But did not work.

That's why I explicitly set to GEN 4 now.

@hypergeome I learned something new from your situation that PEG with RTX-40 series need to be set to GEN 4 explicitly. I will keep this in mind in case anyone else runs into these issues and is looking for suggestions to try.
