Question Random times Freeze

[giorgosfl]

Hello,

I have an issue with my computer.
While I am using the pc either for work or youtube/netflix or gaming the screens freeze at random time(s) and mouse and keyboard does not work but sound does for a short time after screen freeze. Sometimes it rebooted and other occasions stayed frozen until I pressed the reset button.

My setup has:
OS - Windows 10 Pro / version - 21H1 / os build - 19043.1165
CPU - Intel Core i9 9900K (not overclocked)
CPU Cooler - Corsair h115i
RAM - Corsair 32 GB 3600 Mhz
Motherboard - Asus ROG MAXIMUS XI HERO (WI-FI)
Storage - Samsung SSD 970 EVO Plus 1TB
GPU - NVIDIA GeForce RTX 2080 SUPER
PSU - be quiet! Straight Power 11 850W 80 Plus Platinum Modular Power

What I tried so far

1. Full format with only the necessary drivers and Nvidia and Chrome.
2. MemeTest 86 for each of the 4 ram sticks I have and all together for more than 5 hours.
3. Using single monitor instead of 3
4. FurMark to test GPU
5. Update to latest Bios for my motherboard
6. clear CMOS and flash latest bios again
7. No overclock on ram (xmp)
8. Tested my storage with Samsung Magician for any errors.
9. I played warzone, which is a more demanding game from League of Legends on the gpu, for over 8 hours.

None of the above lead to a freeze or discover the issue

Any suggestions on how to monitor and catch the error to be able to find the culprit ?
Something new to test?

Have your checked your CPU temperature? The 9900K can get quite hot, even at stock speeds. What is your CPU cooler?

Updated my part list to include the cpu cooler. I checked the temperature and it is in normal range.
