Hello Everyone! I've been trying to track down intermittent issues on my machine since a major rebuild and wanted to get other's opinions on the matter. Errors have ranged from a strange soft-lock where Windows mostly stops working over the course of a few minutes, to random reboots without any perceivable cause, to various bluesceen codes. The issues have been going on for the past couple months and I've been doing my best to keep notes on them as I go. I believe, at this point, that it's either the memory or the CPU's memory controller that are giving me the issue... or the motherboard is messing with the memory and breaking things, I'm not sure, but that's why I'm here. Interestingly, the original problem I was facing, the soft freezes, was resolved but now there are other issues.
System Specs. Basically everything is new except the GPU and Motherboard that were brought over from the old build:
CPU: Ryzen 7 5800X3D
Memory: 64GB (4x16GB) Corsair Vengeance RT 3600MHz DDR4 (or 16GB (2x8GB) Corsair Vengeance RGB when testing)
Cooling: Be Quiet Dark Rock Slim, upgraded to Be Quiet Pure Loop 280 when I realized that was nowhere near enough cooling.
Motherboard: MSI B450M Mortar (non-Max) on latest BIOS for 5800X3D support.
GPU: XFX 5700XT Thicc III (Also run with R7 240 and GT710 when testing things)
PSU: Originally a 1000W Seasonic Titanium Prime, but the fan was loud and annoyed me so I replaced it with a 700W Fanless version.
Storage: 2x4TB XPG Spectrix S40G SSD's
OS: Windows 11, reinstalled several times over the course of testing.
Here's the copy of my notes I've been taking, in mostly chronological order, hopefully they're readable enough for y'all to get the gist of what I've been trying:

Code:
Three times so far, a few days apart, I’ve noticed my computer soft-locking. The first sign of failure is YouTube video playback pausing and failing to restart. Discord will freeze, the clock and taskbar freeze, control alt delete does nothing, nor does control shift escape. Some apps can still be clicked on, some can be scrolled through and the windows moved around, but once clicked off of will be locked and unusable again. The start menu can be brought up but the search bar will not function and the menu will go unresponsive when clicked off of. A hard reset is the only solution. Update: Probably up to a dozen so far. Can be a few days or less than an hour between freezes. Also can happen when playing games, the game will freeze at the same time as video playback.
No errors appear on the Event Viewer until after the reboot, and then it's the usual "Windows unexpectedly rebooted" errors.
SFC /scannow found no corrupted files.
Turning on driver verifier makes the system run very slowly and use lots of processor time (expected). Attempting to run a game causes the system to hard lock and reboot. There is no BSOD or error in the event viewer. Disabled driver verifier.
Task Manager shows no abnormal resource usage when the freeze occurs. MSI Afterburner stops monitoring when the freeze happens, but the graphs can still be scrolled through and show nothing strange apart from slightly lower GPU usage for a the few seconds between YouTube playback freezing and Afterburner monitoring freezing (expected).
Memory tested, 5 advanced passes of windows memory test. No errors found. Froze again the next day.
Motherboard on latest BIOS, only BIOS available that supports the new processor.
Updated Graphics drivers. Frozen again less than an hour later.
Reinstalled Windows from scratch. A few days later, it’s frozen again.
Noticed before the reinstall but sometimes when leaving the machine on with the monitors off and returning later (eg. sleeping and coming back in the morning), turning on the monitors will lead to no GPU output and requires a restart. Possibly the same freezing as before but with the GPU not outputting? Noticed it happening after swapping from VBIOS 1 to 2, and still happens after changing from 2 to 1. Update: Hasn't happened since Windows reinstall.
Keyboard sometimes fails to connect. On one occasion I played a game for several minutes without noticing the keyboard wasn’t working. Opening iCUE reconnected it. Upon a reboot (after freeze) it once again wasn’t working for several seconds, followed by windows installing a device labeled “PCI Bus”. Update: Seemingly fixed after reinstalling iCUE
Replaced power supply, no change in behavior. Not really a troubleshooting step but it was loud and annoying me, so I got a new one.
Checked memory speed. A-XMP was never enabled since rebuild, RAM speed was limited to 2400, won’t POST at A-XMP 3600 and resets to 2400.
Tested with known good memory. Froze again. Put original memory back in.
Testing with another GPU (R7 240). Multiple bluescreens. GPU driver errors?
- netio.sys (missed stop code)
- kernel security check failure
- tcpip.sys system service exception (in safe mode w/networking)
- Pool corruption in file area
- kernel security check failure (in safe mode)
- classpnp.sys kmode exception not handled
Eventually got it to download and run DDU, removing GPU drivers. Still crashing within 15 seconds of windows boot with similar errors. Reset Windows from within the recovery menu.
- IRQL not less than or equal, black screen of death mid-reset, no file listed as the cause.
Tested *another* GPU, get a few more immediate bluescreens related to system files. From this point, the machine is running a GT710.
I figure windows is just borked at this point, reinstall windows.
- Cache Manager, crash mid install
Try again
- kernel security check failure
Try again, unplugged all other drives except the USB key with the iso on it and the drive I’m installing it to.
- “Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x8007025D
Try again
- Cache Manager crash again
Try again, swapped to a known good SSD
- “Windows installation encountered an unexpected error, verify the installation sources are accessible, and restart the installation. Error code: 0xC0000005”
Try again
- Cache Manager crash again
Bad .iso? Redownload .iso and retry.
- IRQL not less than or equal
Try again
- fvevol.sys, kmode exception not handled
Swap back to known good memory again. Made it through the install.
Now running with old memory, GT 710 GPU, old SSD. Ran for a day without issues. Started slowly putting new components back in.
Reinstalled new SSD and reinstalled Windows. Ran for a weekend without issues.
Reinstalled new memory. Won’t POST if more than one stick is installed at rated speed.
Testing revealed that at any preset over 3000MHz memory speed, slot 3 won’t function with the new memory kit.
Strangely worked fine at 3200 with the old memory kit in slot 1 and 3.
Running it now at 2933MHz preset in motherboard BIOS because it won't post at A-XMP speeds.
Crashed after about a day: PFN List Corrupt
No crashes for a few more days, reinstalled new GPU.
Couple of days later I woke up to a driver timeout error crash report from the GPU software and later in the day the computer restarted for no notable reason.
Memory Management error maybe 20 mins later, then again 2 minutes after that.
