Question Slow windows 11 Boot on MSI PRO Z790-A WIFI – Over 60 Seconds Before Windows Loads

[Hardestware]

Hi everyone, I recently built a new PC, but I'm experiencing very slow boot times — around 60 to 80+ seconds before Windows even starts loading.


Specs:

• Motherboard: MSI PRO Z790-A WIFI (latest BIOS, version dated 20.05.2025)
• CPU: Intel Core i7-14700
• RAM: 32GB (2x16GB G.Skill Trident DDR5-6400, same model)
• GPU: NVIDIA RTX 2060 Super Gaming X (MSI)
• Storage: Lexar NM790 1TB NVMe M.2 SSD
• OS: Windows 11 UEFI install

What I’ve already tried:

• Disabled Memory Training on each boot
• Enabled Fast Boot
• Disabled CSM
• Set my NVMe as the first boot drive
• Disconnected all other drives
• Updated BIOS to latest version
• Disabled Full Screen Logo and set POST delay to 0
• Secure Boot is properly configured

Yet, the system still takes about 1 minute or more just to POST.


For comparison:
My old PC with an H61 motherboard, i7-3770, and SATA SSD boots to Windows in under 18 seconds from pressing the power button.


Is this a known issue with Z790 or Lexar NM790? Any ideas on what else to check?


Thanks in advance!

"Storage devices: 4 HDD and 2 SSD NVme M2, but I tried turn of all other and boot only with system M2 ssd, no changes."

Did you physically unplug the other drives?

Did you alter any settings in windows like sleep modes, hybrid ...?

restarting windows will take longer, cause all will be loaded freshly
shutting down and powering on will be quicker, cause some processes already loaded

yes I physically unpluged the other drives - no result

No, I haven't touched those settings.

My old pc runs fast in restarting like the same powering on, both takes 18 seconds, My Victus laptom too faster in restart and in power on

run memtest
check cpu socket of the motherboard for bent or discolored pins, CPU contacts as well for discoloration.

In task manager click on startup apps.
There, you will see the last bios time. Mine shows 13.8 seconds.
If much longer, your motherboard may be checking ram first or taking some other action.
Unused adapters may take some time before they are detected as not there.

Test your cmos battery. If it has failed, it will not hold settings across a full power off.

Regardless, consider not powering off at all.
Use sleep to ram(no hibernate)
That puts the pc and monitor into a very low power state, essentially like powered off.
Sleep and wake become a handful of seconds.
