I completely reset my Inspiron 9470 to factory setup, and after all of the Windows updates everything seemed fine. I then saw that the Dell updater recommended updating several things including the bios, so I I did.

Have you actually allowed the enhanced ePSA pre-boot diagnostics to run to completion or tried running any of Dell's online diagnostics? The Diagnostics tab on your Inspiron 3470 support page has a link to the SupportAssist Pre-Boot System Performance Check lookup page where you can enter the error code generated by your ePSA diagnostics. See the Dell support article Resolve Hardware Issues With Integrated and Online Diagnostics (SupportAssist ePSA, ePSA, or PSA Error Codes) for more information.

As a first troubleshooting step I'd suggest running System File Checker (sfc / scannow) from an elevated command prompt with Administrator rights (see Option 3 of the TenForums tutorial How to Repair System Files with SFC Command in Windows 10) just to make sure your Win 10 v21H2 system files weren't corrupted during the update from v1909. If System File Checker does not find any issues with your system files it should report that "Windows Resource Protection did not find any integrity violations." See the ghacks.net article Use DISM to Fix Issues SFC Can't if System File Checker finds issues that it can't automatically repair.

Well... your not gonna believe this... There is an issue with plugging my my keyboard into certain USB ports, If I plug it into the ports in the back, not in line with the HDMI port, it goes into the pre-boot diagnostics every time, there is a quick little yellow message before diags load, saying diagnostics selected. I am able to boot normally if I use the ports that are in line with the HDMI port, of the front ports. It is a Lenovo keyboard, and I don't have another one handy to see if a different brand has the same issue.

That's good news. I had composed a (very long) reply that included a link to the Dell support article How to Recover the BIOS on a Dell Computer or Tablet but I won't bother posting any further troubleshooting tips until I hear how your keyboard swap goes.

I was given the computer by a friend, my Alienware Aurora tower(I7 970) was starting to get random freezes(even before boot), So I wanted to clear out his old stuff and start from a clean system, and use this machine for backup, and possibly go to Win 11 if it's good.

You mentioned that you tried "disabling secure boot, and several other bios settings to no avail". Secure Boot is disabled on my own Inspiron 5584 (and I often run a diagnostic with the free Belarc Advisor utility after a BIOS update just to ensure it hasn't been enabled) but if you find your Inspiron 3470 has problems waking from sleep mode or exhibits some other odd behaviour you can restore your BIOS settings back to their defaults as instructed in the Dell support article How to Restore the BIOS (System Setup) Defaults on a Dell Product.

If you haven't already done so I'd also suggest that you disable the Win 10 Fast Startup option (Control Panel Hardware and Sound Power Options Choose What the Power Buttons Do Shutdown Settings Turn on Fast Startup) as instructed in Option 1 of the TenForums tutorial How to Turn On or Off Fast Startup in Windows 10. Fast Startup (also known as hybrid boot-up / hybrid shutdown) can interfere with the loading of drivers and services at boot-up for a variety of programs and cause all sorts of unexpected glitches and strange behavior. Fast Startup can even interfere with Windows Update (see the MS support article Updates May Not Be Installed With Fast Startup in Windows 10) so I normally recommend that Win 8.x and Win 10 users disable this setting. Some users have reported that Fast Startup was re-enabled after a Windows version update (e.g., after a Feature update from v21H1 to v21H2) so I occasionally check the status of this setting as well.

If you continue to see any glitchy behaviour on your Inspiron 3470 make sure you remove all the outdated trial versions of third-party software that were installed at the factory . For example, I reset my Inspiron 5584 to factory condition in August 2020 after it wouldn't boot up [i.e., it would get stuck on the black splash screen with the Dell logo, there were no beep codes during the power-on self test (POST) to indicate there was a hardware problem, and I couldn't access Dell's SupportAssist OS Recovery) and one of the first things I did after the reset to factory condition was to uninstall the trial versions of McAfee and MS Office 365 using the removal tools provided by the program developer. For example, I uninstalled McAfee LiveSafe from Control Panel Programs Programs and Features and then wiped the last traces off my system with the McAfee Consumer Product Removal tool MCPR.exe) to ensure remnants wouldn't interfere with my Microsoft Defender antivirus.

Could you please check the model of your Dell computer and let us know what Windows operating system is installed? The closest match I could find to "Inspiron 15 3000 2020" on the Dell support site was for a legacy Inspiron 3000 at -ca/product-support/product/inspiron-3000/drivers, and Dell hasn't released driver or BIOS updates for the Inspiron 3000 since the year 2000. Is this a refurbished Dell computer or was it purchased brand new from Dell in 2020?

Could you also explain on what you mean by "the screen being broken"? For example, when you power on your computer do you see a white Dell logo on a black background or hear any beep codes (see the support article Understanding Beep Codes on a Dell Laptops) during the initial POST (Power-On Self-Test), or do you mean your display is always black? If you have the same problem as the original poster of this thread, s-petersen, then your screen should display some sort of error code or warning that is generated by the Dell SupportAssist OS Recovery software when it runs its own pre-boot diagnostic check.

When your laptop displays the error message 'No bootable devices found,' the computer cannot locate any storage device containing the necessary files to start the operating system. This can happen due to various reasons, such as incorrect boot device selection, corrupted boot sectors, or faulty hardware connections.

Step 2:Run a startup or automatic repair using a Windows installation disc or USB drive. Rebuild the Master Boot Record (MBR) using specialized tools or commands. Moreover, perform a clean installation of Windows if all else fails.

Step 2:This will enter the BIOS or UEFI setup menu, where you can configure various settings related to your computer's hardware and boot options. Navigate through the BIOS setup using the arrow keys, make the necessary changes, and save your settings before exiting.
