Question Intel i5 9300H frequency/voltage drop and shutdown

Hi, everyone.

I am facing an issue of shutting off my laptop while playing videogames.

Whenever I play a game titles (even 5 years old) I noticed a significant fps drop (from ~80 fps to 10-20fps) for a 3-5 seconds. After 3-4th rep laptop just shuts off without any errors in a Windows logs.
I've started to investigate a problem. I've done some stress test like AIDA64 and at the same time I've monitored a hardware paramters (temperatures, voltage, power, frequency).

During CPU stress test I haven't noticed any problems. Laptop was running for about 15 minutes at 100% load (frequency 3800-4000 Mhz and voltage aprx. 1.200 V). CPU temperatures stabilize at ~84 C.
During GPU stress test CPU utilized ~26% and GPU utilized at 100%. But I got a CPU throttling warning (30-50%) by some reason. It takes some time to speed up fans and later on throttling value drops to 10-15%. CPU rises up to 96 C and then stabilizes at 85-87 C. GPU heats up to ~ 85 C
During CPU and GPU test (simultaneously) picture appears slightly better. It started with 15% throttling (CPU utilization 100% and both GPU at 100%) for 3-4 mins and after cooling fans coped up a temperature rised it stabilizes at 80 C.
Stress tests didn't cause a shut down for a time I've carried out test.
But once I run some heavy games every 5-20 minutes I get a fps drop. And after some time laptop just shuts down.
I tried to monitor a hardware parameters duing gameplay.
CPU :
Utilization at 40-60%;
Temperatures at 75-85 C;
Frequency 3800-4000 Mhz;
Voltage 1.2 V.

GPU:
Utilization at 80-100%
Temperatures at 75-85 C;


During a fps drop I noticed also a frequency and voltage drop (0.6 V / 800 Mhz respectively).
Windows (11) was recently reinstalled to isolate a problem and make sure it's not a software problem. Last windows update - installed. Last drivers update - installed.
Thermal paste was replaced 1 month ago by service. And the problem occurs just 1 month after. I suspect a power failure, motherboard damage or GPU damage but from the other hand All the symptoms of overheating besides the temperatures are in range as per HWMonitor.
Does somebody has any idea where to search and how to troubleshoot ?
I've viewed the similar topic but all of them about poor performance. But I really worry regarding shutdowns as it's a really bad indicator.
Appreciate any advise.
Thank You.

Laptop specs:
Brand : Acer Nitro 5 ;
CPU: Intel i5 9300H;
GPU: Nvidia RTX2060, 6 Gb (Intel 630 integrated);
RAM: 16 Gb DDR4;

Did you ever solve this problem?

Try running ThrottleStop.

Upload some screenshots of the FIVR and TPL windows to

so I can see your settings. Turn on the Log File option so you have a record of your CPU performance while playing a game. Copy and paste the log file data to

www.pastebin.com

This is a classic throttling problem. When your CPU slows down to this speed, open up the ThrottleStop Limit Reasons window and have a look for any boxes lighting up red. This will help determine the reason for throttling. The log file should help confirm what is happening and why.
