PC crashing when I launch a game

Hello everyone,
I'm quite desperate... I've had a PC for a little over a year, but for the past few months, it crashes systematically as soon as I launch a game (Apex Legends, Valorant, etc.).
Symptoms:
- The PC works very well for office tasks.
- As soon as I play, it works for a few days then crashes.
- During the crash: motherboard logo + stuttering loading indicator. Then, “diagnosing your device” and a blue screen offering reset or BIOS.
- After restarting, the problem reoccurs.
What I have already tried:
- Windows reset with USB drive → works for a few days, then the problem returns.
- SSD change → no effect.
- RAM change → no effect.
- Reinstallation of graphics drivers → no effect.
- Taken to a repair shop → everything seemed fine, Windows reinstalled → works for 1-2 months then crashes again.
- Event viewer → unable to identify the problem.
Configuration:
- Ryzen 5 5600
- MSI B550 Pro VDH WiFi
- RX 6750 XT
- Acer Predator GM7 2 TB M.2 NVMe PCIe 4.0 SSD
- XPG D35G 2x16 GB DDR4 3200 MHz RAM
What I'm still considering:
- Updating the BIOS
- Creating a new bootable USB drive for Windows
If anyone has encountered this type of problem or has ideas on how to solve it, I would appreciate it! Thanks in advance ????

Hello,
Given everything you've already tested, we can clearly rule out Windows, the SSD, and the RAM. The fact that the PC is stable during office tasks but crashes only under GPU load (gaming).
Here are the most serious avenues to explore, in order of priority:
1. BIOS update (strongly recommended)
Update the BIOS to the latest stable MSI version, then:
load the default settings
temporarily disable XMP/DOCP to test for stability
2. Power supply (very suspect)
You didn’t mention the model or wattage of the power supply, but:
the RX 6750 XT is demanding
an unstable power supply can cause exactly this type of restart + blue screen
To check: actual wattage (minimum 650W from a reliable brand)
age of the power supply
PCIe cables well-separated (not a Y cable)
This is the number one cause of crashes during gaming after a few minutes/hours.
3. Temperatures under load
Even if everything seems “OK” at rest:
monitor CPU + GPU + motherboard VRM while gaming
if the PC crashes without a clear message, a thermal protection may activate
4. Drivers: clean reinstall even if already attempted
Hello
You need to control the temperatures; that's often where the problem lies.
Install https://userdiag.com/fr/ and run a long diagnostic, then paste the link to the results here.
Hello,
There is no overheating,
However, like many beginners, you are not using XMP for the RAM, which can lead to a loss in performance; you are not making the most of your RAM.
In the second gaming test, you are not utilizing the full power of the graphics card, which is really strange; I noticed that its voltage and frequency varied a lot.
In fact, winux is right, your setup does not require a power supply greater than 650w; however, crashes can very well be caused by a faulty power supply when it is under load regardless of its wattage. Before replacing it, trying another one, even a less powerful one, could have helped rule out a power supply issue.
Hello,
To start with, the "MSI B550 Pro VDH WiFi" is not for me, a motherboard made for gaming!
That said, you really went to great lengths... why didn't you just uninstall, clean the registry, and reinstall the game!?
In addition, if you have a BIOS update to do, you need to do it.
Happy New Year's Eve and Merry Christmas ;-)
Hello,
There are no components that are strictly gaming; before this term existed, a motherboard was supposed to be able to provide intensive use, whether for gaming or professional purposes, it doesn't change anything. The most important thing is the chipset and the VRM phases if we overclock or use an energy-hungry CPU for longevity.
I have 250 games B 550 1070 custom, what's the problem? Come on bo7, you'll see, you won't understand ^^ one thing to know about the BIOS, if I had known, I wouldn't have done it, because the DisplayPort struggles with the last update, yellow LED problem very well-known on these motherboards ^^
As for his problem, something is surely giving out, but what, there's only the GPU and the motherboard left in that case.
Thank you very much for your response. My power supply is an MSI MAG A650BN, it's a year and a half old.
As for the PCIe cables, I will try my best to separate them.
I will also update the BIOS and monitor the temperatures.
I will get back to you to let you know if it worked. Thanks again for your time and help...
