Hi all,

I would really appreciate some insight on this one.

I've recently upgraded my PC. Installed the EK water block on a 3090. The motherboard is Asus Maximus XI.

I've connected 4 monitors to the machine (3xDP 1xHDMI)

Occasionally when I start I get no signal. My monitors acknowledge the power, by turning on but then no progress. And it gets stuck on Q-Code AE. And it doesn't show the BIOS screen or anything.

The only relevant information to booting is that I have to select legacy mode instead of UEFI.

I know AE is a meaningless code to truly diagnose an issue by itself. as it just indicated booting OS. So if it gets stuck on that it might mean it can't find an OS. But that's not the issue because a restart fixes the problem. And I can shut it down and restart it 10 times over, no issue. But sometimes it might happen again.

I've done all kinds of stress tests on the card. Left games running for 24hours etc. All tests pass with flying colors.

Can this be GPU related?

Any thoughts would be really appreciated.

Many thanks.

I would check to make sure video card is seated properly. Check all monitor cables for proper fitment. Make sure this is no dust in any of the DP/HDMI ports.

You could try just running one monitor for a while and see if it still happens. Try all four monitors individually for a period of time to see if problem occurs. Then try two monitors at the same time.

Sometimes you just have to live with small issues like these. Custom setups can be a pain to diagnose and the time and effort might not be worth it. As long as everything functions fine when it does boot up, I wouldn't worry to much.
