Recently, I've got some BSODs with this error code: WHEA_UNCORRECTABLE_ERROR. It usually happens 1-2 minutes after my computer boots up. Could you help me figure out why it happens?

Thanks in advance.

You need to disable Overclock in BIOS, try to these steps below:

  1. Navigate to Update and Security, and then to Recovery tab
  2. Click on Advanced Startup and your computer will restart
  3. On advanced startup, click Troubleshoot, then Advanced Options and then UEFI Firmware Settings
  4. Click Restart
  5. After the computer is restarted, it should open BIOS automatically, so go Advanced tab
  6. Than to Performance, and look for Overclocking
  7. Make sure overclocking is disabled

If your PC doesn't support overclocking, you can try check for drivers from Safe Mode Windows in method#2 or #3 from this tutorial http://howtoinstallwindows10.com/fix-whea_uncorrectable_error-windows-108-1/

My CPU doesn't support overclocking as well as my Dell mobo.

We will need several more dump files to really see what's going on with your system, but the reports point to a problem with the CPU. Is this DELL still under warranty? If not, remove the CMOS battery to reset the BIOS. I see you're running Prime95... good work. What type of test are you running? Also, when does the BSOD occur, when the system is cold (in the morning) or... ?

I remember that I have deleted Prime95 from my computer. Also, I was running it to find prime numbers but didn't see any BSOD.
This BSOD usually happens when I turn on my computer after having shut it down for many hours. And it only happens once.
For example: I turned off the computer at some time. The next day, I turned my computer on then after 1-2 minutes, this BSOD occur. After that, I can use my computer for many hours without encountering any BSOD. This keeps happening over and over again.

Sorry if I ask again, is this DELL under warranty? Will you please run MemTest86 for a minimum of eight passes? Here's a good guide if you need help. Also, please run Seagate SeaTools for Windows. Be sure to test all your drives with the S.M.A.R.T. and Long Generic tests. We need to ensure the RAM and HDD are OK first, even though the prime suspect is the CPU.

I guess it's not under warranty anymore because I have bought it 3 years ago. I'll try Memtest86

Good to know... that will expand our options. Do you know how to update your BIOS, by any chance? Suggest you run the Intel Processor Diagnostic Tool, when you're free.

Here's another dump file.

This morning I tried Memtest but I forgot to set it to 8 passes so it ran only 4 passes without errors. I'll do Memtest again later.

Will wait for you to complete the MemTest, the HDD test, and the CPU stress test before moving on.

Looking good. Try running Prime95 (read the details in the link) to stress the system. As mentioned earlier, also try reseating the CMOS battery, or even replacing it.

Can you explain how the CMOS battery can cause BSOD?

It's not directly "causing" the BSOD. Removing the CMOS battery typically resets the BIOS and any improper CPU timings. This sometimes helps with 0x124s.

 

What I find so weird about this case is how the system BSODs when cold... :o

Me too. The weather in here isn't so cold. It's not even winter :lmao:

 

Also, can I let the Prime95 test run the whole night?
