Question Computer keeps freezing and rebooting after 3-4 hours of gaming

[CaptainMalenko]

As the title says I did a full on upgrade of my rig around November last year and I've been having problems the past month that while I'm playing any intensive game my system freezes and reboots after a couple of hours. I've been troubleshooting best I can: updated BioS, checked to see if it was any driver, checked windows, did stress tests (didn't crash only in this situation) I ended up also upgrading my PSU in case that was the issue but it continued, I've tested the RAM (memtest and booting the system with both sticks individually socketed also no issue), changed which outlet my computer is connected to (no power strip), I thought maybe it was the GPU so I tried to RMA but retailer said there didn't seem to be any issues with it and today I got it back so I decided to try again while having HWinfo log (which I have but I don't exactly know what to look for) the whole duration up until it crashed again on almost the 5 hour mark. So I'm out of ideas if anyone could help out, it's been a huge headache the past month.

This are my specs:
CPU: AMD Ryzen 7 7800X3D
Motherboard: ASRock B650M Pro RS
RAM: 2 × G.Skill F5-6000J3038F16G
GPU: MSI GeForce RTX 4070 SUPER 12G VENTUS 2X OC
PSU: Corsair RM1000x SHIFT Fully Modular ATX Power Supply

Welcome to the forums, newcomer!

How are you cooling the processor? Make and model of your case? Number and orientation of the fans in said case?

updated BioS,
For the sake of relevance, please state the BIOS version for your motherboard.

I ended up also upgrading my PSU in case that was the issue but it continued,
What PSU were you on prior to the RMx Shift unit listed above?

I thought maybe it was the GPU so I tried to RMA but retailer said there didn't seem to be any issues with it and today I got it back
Did they stress test the system with you present? If so, the only thing that would've changed would be the wall outlet/source of power. Try and relocate to another wall outlet.

Look in Window's Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error codes, warnings, or even informational events just before or at the time of the system freezes.

Also look in Task Scheduler for any rules that trigger some app or utility based on a 5 hour time trigger.

Thank you, first time so sorry if I left out some important info.

For the BioS I'm at version 3.20
My previous PSU was a Corsair HX750i Full Modular
I have a masterliquid ML240L V2 RGB White Edition CPU Liquid Cooler on a Corsair 5000D ATX case tho I cannot remember how my fans are setup at the moment.

Only thing showing up on event viewer is the event 41, Kernel-Power

Check your Antivirus schedule that may be triggered at the 5 hour time. Also just a suggestion reset the CMOS this will default the mobo to factory settings. If it POSTS ok run HWINFO onscreen and Cinebench 23 and check the temperatures during the test compared to idle temps. Check that your CPU is within the correct temperature range parameters for your CPU. See if it triggers the event 41 power error. Please consider these tests and post your results. You can apply any tweaks for gaming and productivity if it is running stable. If it is still having issues, you may want to run MEMTest86 on your installed RAM see if any errors come up. Bad RAM is known to commonly cause the Kernel Power Event 41 error. All the best and hope you find the solution asap, so you can enjoy your PC once again.

I've done all this already, memtest showed no errors, I ran the rig with one stick of ran and then the other and was also no issues. My cpu temps seem to be fine 60C mid gaming
