WHEA_UNCORRECTABLE_ERROR on every startup

Question

Almost every time I restart my PC, it freezes in the middle of startup. Either it completely freezes on the Lenovo loading screen and nothing happens at all, or I get the blue screen and the "WHEA_UNCORRECTABLE_ERROR" message. I suspect this is happening after my computer automatically updates, so I've temporarily paused updates for now and uninstalled the most recent ones. 

Usually I turn my PC on and off until I get to the WinRE screen, then click "Continue to Windows 10" and I can use it normally from there. It's just annoying. I suppose I could just delay updates indefinitely but I'm not 100% sure that's the cause of the problem, and that also just seems like a bad idea generally?? 

I've read that this error could also mean I need to update my driver, but in Device Manager it says my driver (Intel(R) UHD Graphics 620) is up to date. I've tried resetting my PC as well and that didn't resolve the issue.

My device is a Lenovo Ideapad Yoga 920. Any help at all is appreciated.

Hi SOP. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

If any steps cannot be performed normally then try them in Safe Mode with Networking or Safe Mode accessed by one of the illustrated steps in this guide: https://www.digitalcitizen.life/4-ways-boot-saf...

1. Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

2. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue with the other steps to go over your install most thoroughly.

3. If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1903 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m....

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to rate my post, I will keep working with you until it's resolved.
