Question New build crashes randomly when playing games

[King Smoochy Wallice III]

Ive been having a bunch of issues with a PC I recently built. As the titles says it crashes randomly when playing games and only when playing games. The only two games I have to play so far are Valorant and Diablo IV. On a fresh boot I can play for maybe an hour or so before it crashes, but after the first crash it will continue to do so sporadically. Sometimes the game just crashes other times it blue screens. Ive done a bunch of trouble shooting things already like updating drivers, reinstalling drivers, restoring system to factory, installing games on different drives but still I get crashes. I even switched gpus from a rtx 7900xtx to a 4070 thinking that was the cause. I am at my wits end fighting this thing any and all help would be greatly appreciated.
Specs:
AMD ryzen 9 7900x, ASUS prime B650-plus, GFORCE RTX 4070, 850 watt power supply, 32 gb of ram, 1 tb m2.e, 2 tb ssd, OS windows 11

Hey there,

So, when you say crash, does it restart, or mostly bluescreen or any error codes?

What is the exact PSU, make and model?

What bios are you running on the mobo?

More often than not when it crashes its just the game that freezes. I have gotten blue screen a couple of times. The psu is a thermaltake toughpower gf a3 850 watt. I dont know what bios is running is running on it though.

You can check the bios by opening up CPU-z and clicking on the motherboard tab. This will tell you.

Test your ram outside of windows with memtest86+. If it gives any errors, your ram could be at fault.

Your PSU is very good, so I don't think it's that.

Bios is possibly key here as they newer bios' bring fixes for bugs, and mem compatibility.

Check the event logs for any system/application errors. Do the games have debugging/crash reports that are enabled or can be enabled? If you get a blue screen, you can use Windbg to look through the crash dump from a BSOD and see what caused the system halt. You can also use Windows Memory Diagnostic or MemTest to test your RAM for errors.
