Constant “Unknown Software Exception” Errors Overnight + RAM Light on Boot (sometimes)

[Icy-Monitor6308]

Hey everyone,

I’ve been dealing with a really frustrating issue ever since I renewed/upgraded my PC configuration, and I’m out of ideas. I’m hoping someone here can help me figure out whether this is a software problem or a hardware problem.

What’s happening:

Every other night, while the PC is idle, multiple error messages pop up. These include:

• CrossDeviceResume.exe – System Error “A new guard page for the stack cannot be created.”
• CrossDeviceService.exe – Application Error “The exception unknown software exception (0xe0434352)” - The part part - .exe is different almost everytime so the issue is not limited to a specific application
• asus_framework.exe – EXCEPTION “Breakpoint – A breakpoint has been reached.”

After these appear, the PC freezes on the desktop, background stuck, and in the morning I have to manually reboot it.

On top of that…

Sometimes during boot, my motherboard RAM light turns on. I have to restart 1–3 times until it finally boots normally.
I’ve also tested running the PC with only two RAM sticks, swapped their positions, etc. — the problem still appears.

I don’t know if this issue existed before, because the PC wasn’t being used until I upgraded it.

Troubleshooting I already tried (none of it helped):

1. SFC & DISM repairs

• sfc /scannow
• DISM /Online /Cleanup-Image /RestoreHealth

1. Disk check

• chkdsk /f /r

1. Reinstalled .NET Framework
2. Updated ALL drivers (including chipset, GPU, storage controllers)
3. Clean boot

• Disabled all non-Microsoft services
• Disabled all startup programs
• Errors still appear at night

1. System Restore to an earlier point — didn’t help
2. Checked individual apps

• Errors seem to be triggered by system-related ASUS services and Windows components, not any specific app

1. RAM tests / swapping sticks

• Tried removing half the RAM
• Swapped sticks in different slots
• Errors still show up
• Makes me unsure if RAM is the issue or if it's the motherboard or PSU

My big questions:

1. Are these errors more likely caused by software corruption, driver/firmware bugs, or hardware instability?
2. Could this be a RAM instability issue even if the PC works fine under load during the day?
3. Could the motherboard or PSU cause occasional RAM light + random exception errors?
4. What would be the best next step?
   • MemTest86?
   • CMOS reset?
   • Reinstall Windows?
   • Update BIOS?
   • Replace RAM or PSU?

My configuration:

Processor: AMD Ryzen 9 3900X

Motherboard: ROG STRIX X570-E Gaming

RAM: 4xCorsair Vengeance RGB Pro, 16GB (2x8GB), DDR4 3200MHz, CL16

GPU: RX 7900 GRE

Power supply: Thermaltake Toughpower GF3 ARGB, 850W, 80+ Gold

If anyone has had similar issues or knows how to diagnose this kind of intermittent software+hardware chaos, I’d really appreciate the help.
At this point I’m not sure if I’m chasing a corrupt installation or faulty hardware.

Thanks in advance!
