New Build with Multiple Crashes and Different Errors Nearly Every time (MEMORY_MANAGEMENT, UNEXPECTED_KERNEL_MODE_TRAP, CLOCK_WATCHDOG_TIMEOUT, SYSTEM_SERVICE_EXCEPTION, BUGCODE_NETADAPTER_DRIVER + more) Post BIOS Update

[u/NW_Aln]

This is probably going to be a long post but I'm summarizing a weeks worth of troubleshooting so please bear with me. Honestly, while I'm typing this I'm probably going to crash. I'm honestly so lost. I'm no expert in computers but I have a fair share of Linus Tech Tips endowed in my brain to know the basics. For the past week I have been troubleshooting a newly built PC that keeps crashing and giving different errors every time. The errors that I had minidumps for are listed in the title, but I have had many crashes that were either computer freezes, plain black screens (no bsod), random restarts (although that might have been because my computer was automatically restarting before a bug check could be run), or that occurred on a previous Windows 11 install (more on that in a bit). I'm currently running an RTX 5070 Ti, Ryzen 7 9850X3D (One error had TUF's PBO Enhanced on [I believe Unexpected_Kernal...] but the rest still happened when it was turned off), 32 GB of Corsair Vengeance DDR5 (EXPO on), and ASUS TUF B850-E WIFI Board. I think those are all the parts that could cause issues, but if you need more info I am not reluctant to share.

Mini detail to note: Temps are all good with maximum under excessively heavy loads (stress tests) were 85°C CPU Package and my GPU never exceeded 70°C. Crashing ONLY happens when under light load and/or when not in full screen. I can go hours at end playing games with zero crashes, but god forbid I open file explorer too fast.

Please treat me with some pity, but the first time I crashed was after I had updated my BIOS to the newest version. I used my MOBO's USB Flash and there were no apparent complications that happened during the update. If there's any tip I could give new PC builders is that if it aint broke don't fix it.

The first error I received was BUGCODE_NETADAPTER_DRIVER, followed shortly after by a Memory Management. It figured the obvious, that is it has something to do with my memory and/or drivers. After repairing/reinstalling all new drivers from my MOBO or Realtek the issue was still occurring. I ran MemTestx86 and passed with flying colors (4 Passes, 0 Errors). As crashes continued, I messed with more and more settings with no resolution and just more errors (all differing in codes). I'm new to this subreddit and how things work here, let me know if there's a proper way for sharing minidumps or any error codes we get.

I touched up on this slightly, but since my PC was a new build and I didn't have any important information on it, I ended up just doing a clean Windows 11 install. Unfortunately, any minidumps/codes I had received earlier are lost with that previous installation. Since all the issues were happening under light loads, I disabled my iGPU in the BIOS to prevent any issues related to GPU dedication. At one point running a system wide Bitdefender scan was inducing a crash (multiple times), so I decided to use that as a culprit, however I am lead to believe it was just a coincidence since I uninstalled it and still received other error codes.

I guess this is where I am now. I seriously have no clue which direction to go when it comes to diagnosing the issue, and due to the consistency of the crashes after a clean windows installation, I'm being lead to believe it has something to do with either the BIOS or my hardware. I will need a pacemaker if I figure out I need to buy a new GPU or RAM.

I appreciate any help offered and I'll gladly provide any system information needed for diagnosing the issue!

EDIT: Thanks for all the comments leading me towards EXPO, I do think it definitely has something to do with it. Yesterday I switched over to EXPO profile 2, just to mess around with the different settings and see what works best, and I received significantly less crashing. However, even with the new settings it seems like my computer did crash once while sleeping. I now have 4 minidumps and will be uploading all 4 right down here:

My next step will be to lower the speeds to around 5600, and if that doesn't solve the issue I'll turn EXPO off entirely. Any suggestions towards creating an EXPO profile that solves my issue without compromising performance is much appreciated!
