How To Fix The WHEA_Uncorrectable_Error Death

Reader Question:
“Hi Wally, I have been using my laptop for about a year without issues. Now, it gives me this error when I turn it on: WHEA_Uncorrectable_Error.“ - Gabriel N., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: The WHEA_Uncorrectable_Error and other such blue screen errors can seem a bit difficult to solve at first, but they’re actually not that bad. Many people see a blue screen error and think their computer is done and needs to be replaced soon. In fact, blue screen errors can be fixed easily once you know the error message or code.


The WHEA_Uncorrectable_Error or STOP 0×00000124 appears and the computer restarts unexpectedly.

The Windows 8 error message is shown.


A hardware component is malfunctioning and causing Windows to restart.


Here are some ways to fix the WHEA_Uncorrectable_Error.

Use Safe Mode If Windows Won’t Start Normally

You can start the computer in safe mode by following these steps. Click here.

Is It A Hardware Failure?

Hardware problems are the most common reason for the occurrence of blue screen errors. The main hardware components that can cause these problems are the hard drive and the RAM. You can check the hard drive by using CrystalDiskInfo.

Follow these steps to check the RAM:

  1. Start Windows normally or in Safe Mode.
  2. Press Windows Key + R > type mdsched.exe > press Enter
  3. Follow the on-screen instructions

If you can’t boot into Windows normally or even through safe mode, then you should try using hardware scans available in the BIOS to check the hard disk and RAM.

Other Reasons Why This Error Might Be Occurring

Since this error usually means that there is a hardware related problem on the computer. This could mean that the computer’s motherboard or some other major component is not working. You might need to take the computer to a shop to get it examined if both the hard disk and RAM are working.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
