Question Mystery Game Crashes

[Makaru]

So my computer is a home-built PC that works really well *except* sometimes it crashes during gaming. Seems to be game specific and no amount of tweaking settings on said games has ever seemed to help. It doesn't crash instantly and the game seemingly runs fine until a crash(Game freezes and then closes) occurs about 30 minutes - an hour in on average, and depending on the game much sooner or not at all. I want to know what I should do next to figure out the problem.

A few Examples:
Helldivers 2 runs quite well for a few full missions but crashes mid-mission usually at some point, my friends don't seem to have this issue when playing along with me.
Subnautica seems to run for 15-30 minutes before crashing
Final Fantasy 7 Remake *never* crashes
Lethal Company coin toss on whether or not it crashes randomly.
etc.

Some games crash faster than others and some don't crash at all. It's mind-boggling. I've been through game supports and all sorts of fixes and even replaced a few parts in my PC, specifically the RAM. I don't know what I should do next to diagnose it or try and figure out these crashes.

Here's some PC specs

OS: windows 10
Mother Board: MPG B550 GAMING PLUS (MS-7C56)
CPU: AMD Ryzen 5 3600 6-core processor, 3600 Mhz
RAM: 32 GB Corsair VENGEANCE 3600 Mhz
RAM PART NUMBER: CMK32GX4M2D3600C18 A4XOT40559RLPI
GPU: NVIDIA GeForce RTX 4060
PSU: 750 watts CX-750M Model: 75 - 00201D

The event viewer usually brings up a 0xc0000005 error code on these crashes.

Pretty much all of said crash logs look like this:

Hey ther,

Yes, give part number for ram.

Also, what exact PSU are you using. The symptoms point that direction.

When you say crash, do you mean it restarts or BSOD, or freeze?

 

[Makaru]

I edited in the part number and the model number for the PSU (at least I think it was for the PSU it was the big number on the side of it so y'know)

I mean the game freezes and then closes

Access violations can be caused by bugs in the app (game), or even malware, so make sure the game and your GPU driver are updated, and run some scans. I have read though that one of the main reasons Helldivers II gets bad reviews is Sony ended up requiring PS account linking for it, when they initially said they wouldn't. Since this seems to be an MP game, which you likely can't play in offline mode, have you made sure your security is allowing net connection for this game?

Your scans should be for malware, as well as an SFC scan, but for the latter, refresh the image file first.

If none of this produces a solution, there are other free tools like Process Explorer, and Process Monitor that can track what's producing the error.

Gonna give this a bump, I didn't find any malware when I ran it, unsurprisingly, but I did it for the sanity check. How can I tell what is causing the crash? I don't necessarily want to go buy a PSU until I know that that is what will fix it.
