Question PC freezes for 3-5 seconds then keeps going on like nothing happened

[AGC336]

My pc freezes when i play "Rise of the Tomb Raider" for like 3-5 seconds then keeps going like nothing happened. This happens especially when i enter a new area of the map. I tried somethings but it didn't solve my problem. This happened in Nier:Automata when i come across a new area where i didn't visit before but not like in tomb raider. It doesn't freze but fps drops then it's normal again. What might be the cause? Thank you.

My PC:
CPU: Intel i7- 9700k
Motherboard: ASUS TUF Pro Gaming z390
RAM: G-skill 32GB (8x4) 3200mhz
SSD: Samsung EVO 970 M2.2 (where the operator system is loaded)
SSD: Samsung EVO 870 Sata (where the game is loaded ) (I had WD Blue 1tb before that problem occured. I changed it to SSD but the problem continues)
GPU:Asus ROG Strix RTX 2080TI
PSU: Thermaltake Toughpower Grand RGB 850 watt 80plus
OS: Windows 10 64-bit updated
In game (Rise of the Tomb Raider) CPU: 60-70 C temp
GPU:70-75 C temp
FPS: 110-150
All of my system is up to date except bios.
Bought CC Cleaner just for the problem. Corrected all registry. But the problem continues.
I updated my bios but problem is still there.

First, what have you tried to rid the system of the issue? So we're not repeating what you've done.

Second, Thermaltake is the brand of the PSU, 800W is the wattage for the unit and 80puls is the efficiency rating, it does not indicate the model of the unit nor it's quality.

Third, You should list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS: include the version of the OS

Then check and see which version of BIOS is on your motherboard.

Updated BIOS but it didn't work.
