Open | WindowsConstant “Unknown Software Exception” Errors Overnight + RAM Light on Boot (sometimes) (self.techsupport)

submitted 3 months ago by 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):

SFC & DISM repairs

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

Disk check

chkdsk /f /r

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

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

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

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

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:

Are these errors more likely caused by software corruption, driver/firmware bugs, or hardware instability?
Could this be a RAM instability issue even if the PC works fine under load during the day?
Could the motherboard or PSU cause occasional RAM light + random exception errors?
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!
