BSOD, whea uncorrectable error while play League of Legends

Hi kaho000,

Welcome to the 10forums :)

Please start with uninstalling all MSI programs on your system and let me know if it helps :)
If it doesn't we'll continue with troubleshooting.


Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely including PSU, cooling and other used stuff like mouse, keyboard, monitor, case, etc.
The PSU, cooling and other stuff are NOT mentioned in the tool.

In the left corner below in your post you find 'My System Specs'. After clicking it you can find a link a little below that says 'Update your System Spec', click on this link to get to the page where you can fill in your system specs.

MSI programs shouldn't affect your GPU, if it does then there is something else wrong because besides of possible overclocking stuff and temperature readings MSI doesn't interact with the GPU in a way that would affect how the GPU works.

Read carefully before proceeding.

   Warning

If you're overclocking your system, revert back to stock clocks now.

   Note

Test the system once the overclock is removed before continuing with the steps outlined below.

Part One: CPU Stress Test
Part Two: MemTest86+ RAM Diagnostic
Part Three: Hard Drive Diagnostics
Part Four: GPU Stress Test

ONE

 CPU TEST

Run Prime95 and/or IntelBurnTest to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums & CPU - Stress Test Using IntelBurnTest - Windows 7 Help Forums

   Warning

Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.

Make a photo of the result and post it.

TWO

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it please.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Diagnostics Test

 HDD TEST

   Note

Please run HDTune first, in the order posted!

Run HDTune to

• check the health,
• scan for errors, no quick scan but full scan
• run a benchmark.

It may take some time, but please take the time you need to perform it properly.
When above is done please make screenshots of the following

• the health,
• the error scan,
• the benchmark incl. following
  
  • transfer rate,
  • access time,
  • burst rate,
  • cpu usage.

Run SeaTools DOS to check the integrity of your HDD. SeaTools for DOS and Windows - How to Use - Windows 7 Help Forums
Run the long test.

   Note

Do not run SeaTools on an SSD as the results will be invalid.

Make a photo of the result and post it.

Run chkdsk

FOUR

 GPU TEST

Run Furmark to stress test your GPU. FurMark - GPU Stress Test - Windows 10 Forums

   Note

Run Furmark for around 30 minutes.

   Warning

Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them and abort the test if overheating occurs.

Make a photo of the result and post it.

In Furmark you can find a tool called 'GPU-Z' (if you want to install GPU-Z is up to you), when GPU-Z is open click on the 'Sensors' tab, on this tab you can monitor

• the frequency of the GPU,
• the GPU memory clock,
• the temperature,
• the power,
• the load on the GPU,
• Etc.

I would like you to make a screenshot of GPU-Z after you have either cancelled Furmark for any reason or Furmark is finished, post this screenshot in your next reply with the result of Furmark.
