Hi I'm wondering why my motherboards post screen stays on for five minutes then loads up windows 11 fine. It started doing that after I moved my pc from one case to another. But I don't really think it was because of that really. I just don't know what's going on. Like for a week after it was installed into a new case it was fine then it started to do that.
SPECS below:

CPU: 13th Gen Intel Core i9-13900KF 3.00 GHz (4 months)
CPU cooler: icue h170i Elite capellix XT ( 1 month)
Motherboard: Gigabyte Z790 Gaming x ax (3 months)
Ram: 64gb corsair ram DDr5 (5 months)
SSD/HDD: samgsung m.2 1 tb x 2, Kingston fury renegade 2tb, samsung SSD x1, barracuda SSD x2 (all 1 year old)
GPU: Gigabyte Rtx 4090 (5 months)
PSU: Evga superNova G5 1000W 80+ Gold - Full Modular, (1 year old going on 2)
Chassis: Corsair 10000D (1 week old)
OS: Windows 11 Home
Monitor: AOC curved monitors x2

Motherboard bios version, F5 as show in my bio's

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. Include the make and model of your parts. BIOS version for your motherboard at this moment of time?

Do you have 2 x 32GB DIMMs (good) or 4 x 16GB DIMMs (not so good).

Are you running some insanely high XMP settings over 7,000MT/s?

Are you overclocking the CPU and GPU?

I get the impression your system is memory "training" when it starts up, but 5 minutes each time is abnormal.

Disable XMP and any other overclocks and see what happens.

X 4 16 ram
At the moment

At the moment memory frequency is At 4533.33 mt/s
Xmp booster was already disabled
I'm not sure what other overclocking systems are?

I've just now went into the bios then exited it and it boots up instantly now for some reason and I also just shut down my pc and turned it back on and it's fine also but give it a day or couple hours it will take five minutes to turn on again which keeps happening.

Test with one stick of ram see if it makes a diff.

If no help unplug all disk except the OS disk...test.

If this ram came as 2 kits of 2 sticks each see if you can find the mating stick for the stick you tested.

Fit both sticks in the proper slots for dual channel......test.

How do I do a dual channel test. Also I have the sticks in the a2 b2 slots and it's taking awhile to boot past post screen

Have you run MemTest86+ on any of your RAM?

Ideally you need to check each DIMM on its own. Boot the computer up from a MemTest86+ USB memory stick and whilst it's running, make a note if the memory clock rate.

Allow MemTest86+ to complete at least one full pass on each DIMM. Any errors, regard that DIMM as suspect and don't use.

If you wan't to be really thorough (time consuming), check at least one DIMM from each pair in all four memory slots on the motherboard, to rule out any memory channel/socket problems.

That's a good point. I've got several machines with at least eight hard drives and a bunch of SSDs and they do take longer to boot up than a slimmed down system.

BIOS drive interrogation adds another 20 seconds to the boot up time on the 3800X and even longer on the Phenom II X4 965. The 7950X only has five hard disks and three M.2 drives to cope with.

Please let us know when you've run some MemTest86+ tests to confirm all your RAM is OK. If any of the DIMMs fail MemTest86+ it would account for the long boot times.

Equally well, the BIOS might be detecting subtle differences between each pair of DIMMs and failing to assign stable timings.

It might be a good idea to run Thaiphoon Burner on all four DIMMs and compare the primary, secondary and tertiary timings plus the chip details (manufacturer and part type).

You may have two mismatched pairs currently masquerading as matched pairs, e.g. one DIMM with SK Hynix, the other with Samsung B-die. They may not play well together.

A really close inspection of internal SPD registers might uncover unsuspected differences that might help to explain the conundrum.
