Windows Upgrade Help and more

My new Zenbook crashes every single time I start it up. It runs for about ten seconds, then the screen goes completely blue. The error message says something about an "uncorrectable hardware error" but the specific code changes sometimes. It's a model UM5302LA with a Ryzen 7 processor, running Windows 11. I can't get past this blue screen to do anything. What's causing this constant failure right after boot?

This depends on a couple things. I had this issue with a brand new laptop once. From what I have seen, an "uncorrectable hardware error" on a fresh machine often points to faulty RAM or a problem with the SSD. Since you can't get into Windows, your best bet is to contact ASUS support right away for a warranty repair or replacement. Hope that helps.

+1 You could also try booting from a USB recovery drive to see if the problem is with your Windows installation. Another option is to check for a BIOS/UEFI firmware update from ASUS support, as that can sometimes resolve hardware compatibility issues.

That sounds incredibly frustrating, especially with a brand new laptop. An "uncorrectable hardware error" on a Ryzen system often points to a serious issue, but let's try some free, non-invasive steps first.

Since you can't get into Windows, your main tool is the BIOS/UEFI settings. Restart and repeatedly press **F2** (or sometimes **Delete**) as soon as the ASUS logo appears. Once in the BIOS:
1. Look for a "Load Defaults" or "Restore Defaults" option, save and exit. This can fix unstable settings.
2. While in BIOS, see if it runs stable without crashing. If it *still* crashes in BIOS, it strongly suggests a **hardware fault** (likely RAM or SSD on a new machine). You should contact ASUS support or your retailer for a warranty repair/replacement immediately.

If it's stable in BIOS, the issue might be Windows or a driver. From the BIOS, try to access the **Windows Recovery Environment (WinRE)**. You can usually get there by interrupting the startup process 3 times by holding the power button as it crashes. In WinRE, go to **Troubleshoot > Advanced Options > Startup Repair**.

If the problem started after a recent update, you could also try **"Uninstall Updates"** or **"System Restore"** from the same Advanced Options menu.

Since it's new and under warranty, don't hesitate to use that support. You shouldn't have to pay to fix this. Let us know if you can get into the BIOS or WinRE, and we can go from there!

+1 Have you tried booting into safe mode to see if it still crashes?

+1 If it still crashes in safe mode, does it happen immediately or after a similar delay?

Agreed. You could also try a clean boot to see if a background service is causing it. Another option is checking for a BIOS/UEFI update from ASUS support.

Same here. Yeah, and if you're comfortable opening it up, a quick check to make sure the RAM is seated properly can sometimes fix those weird hardware errors.

You could also try booting into safe mode to see if it's a driver issue, since it's a new machine. Good luck!

Yeah, Have you tried checking if there's a BIOS update available from ASUS?
