PC Freeze while playing Rocket League/Overwatch  

I mean those yes.

Please answer my other questions.

Pleaes follow below instructions, some tests you already ran but I do not know some things so please run them again.
Do NOTHING else while performing a test in Windows, if the system freezes while performing a test make a photo of the test and post this photo please so I know you've at least attempted it :)
Please be aware that I may ask you to run a test again if the system froze while performing a test.
There are some DOS tests, SeaTools for the HDD & MemTest86+, if a freeze happens while these tests are running we have possible causes
- If a freeze with a DOS test occured and you didn't ran the other tests, we cannot rule out the other parts due to the fact that multiple parts could cause trouble.

Diagnostics Troubleshooting

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.

THREE

 HDD TEST

Run SeaTools 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 using option TWO
with parameter /r
Disk Check - Windows 7 Help Forums
Upload the chkdsk log Chkdsk Log in Event Viewer - Read in Windows 10 - Windows 10 Forums

Run HDTune to

• scan for errors, no quick scan but full scan
• check the health,
• 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 error scan,
• the health,
• the benchmark incl. following
  
  • transfer rate,
  • access time,
  • burst rate,
  • cpu usage.

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.

Looks like your GPU has cooling issues, is this also when under normal load?

Depends on how much space you have in your case
