So I have been using my MSI Bravo15 B7E for 1.5 year, until recently, it started to shutdown many times when playing games. The 3 games that I play are Honkai Star Rail, Wuthering Waves and Valorant. There is nothing wrong when it comes to Val, but for the 2 other games, it shutdown drastically often. To be clear, this never happened before, i used to play those 2 for hours straight regularly and nothing actually happened. Specifically:

For Honkai Star Rail, it often crashed when I played the new mode of Divergent Universe, when my characters deal too many damage numbers on the screen(In the previous mode, the damage numbers were even crazier and it's completely fine), that's when it's likely to shutdown. This sometimes occured when I farmed in the Corrosion Cavern.
For Wuthering Waves, it shutdown when I use certain ultimates like Changli or Camellya in the open world (espescially when vs bosses), the Whimpering Waves mode(I still have my footage playing the mode smoothly with the characters 11 days ago) and even in materials domains. Things are completely normal when I use them in Tower of Adversity.
At first, i think it happened because of overheating so I lower the minimum and maximum processor state in the power plan from 100 to 99. However, although the CPU and GPU temps only get around 70-75 degree, this problem still exists so I am convinced that this is not due to overheating.
I already got my laptop dust-cleaned and also asked them to put some thermal compound (Arctic MX4) a month ago.
Can anyone here having the same issue or knowing what is going on can tell me cause and the solutions to this please?:( This annoys me so much...
My laptop specs:
CPU: AMD Ryzen™ 5 7535HS
GPU: AMD Radeon™ RX 6550M 4GB GDDR6
RAM: 16GB (8GBx2) DDR5 4800MHz
 
Try to clean install both AMD and Nvidia graphics driver to the version on MSI website.
Use DDU to clean install Nvidia graphics driver.
Use the AMD clean up utility to clean install AMD graphics driver.
Although they are quite old versions, but the version on MSI website could be stabler than the generic versions, and it is the way to check if the issue is related to the software or else.
