[SOLVED] Very Slow Boot Time Windows 10

[Elunor]

I installed CPU-Z, and whilst running it, I also installed HWMONITOR which was a big mistake.

Whilst CPU-Z was running, HWMONITOR started running as well, and then my PC froze and I had to force restart it.

After doing so, the boot time changed from 8 seconds on average, to anytime between 5 and 10 minutes, and during the boot I cannot access the Bios, as if the computer is frozen, even though Windows is loading.

Once Windows loaded, everything seems to be working fine, I uninstalled both CPU-Z and HWMONITOR, and I did a few actions such as restoring the Windows to a different point (a week earlier), cleaning the cache, etc... but nothing works.

Would love to know if anyone had the same issue, or how this issue can be fixed? Is it a Windows issue, or did I mess up the Bios or any hardware?

My system is:

Motherboard: Aorus Z390 AORUS PRO
Processor: Intel Core i9-9900K / 3.60HZ
GPU : RTX 2080 ti EVGA
PSU: Corsair CP-9020131-UK TXM Series 750 W
Ram : Corsair Vengeance RGB PRO 32 GB (4 x 8 GB) DDR4 3200 MHz
CPU cooler : upHere ARGB LED cpu cooler cooling fans
Case : GameMax Abyss ARGB PC Gaming Case, E-ATX
M.2 SSD : EVO 970 NVMe
SATA SSD: EVO 860
Screen: Acer Nitro XV273KPbmiipphzx 27 inch UHD 4K

Go into BIOS the next time you boot up.

Change the POST settings to be as verbose as possible - meaning let the system display what it is doing during the boot process.

You may be able to identify where the boot delay begins and eventually ends allowing the computer to complete the boot.

Once booted be sure to check Task Manager: Ensure that nothing unwanted is being launched at Startup.

Thank you for the answer, but unfortunately, whatever was causing the freeze, prevented me from accessing the Bios.

What I did was to reset the Bios, installing a new Windows (without formatting so all the settings and programs remained as is) but it didn't help, and just when I was about to try using the secondary SSD drive as the main (with a fresh Windows installation), I remembered that I have 3 external HDDs connected to my PC via USB, so I disconnected them, and that solved the problem!

Thank you for your help!
