Hello all,
I left the PC idling on the desktop for about an hour. Came back to find both monitors with black screen and unresponsive. Also, the RAM had went a funny colour; usually all 4 sticks are lit up orange but in this instance one was blue and the other a very weak orange.
Restarted the PC, and noticed my mobo was running through a lot more debug codes than usual. Eventually, it got to 78, hung there for a few seconds, and presented me with "Startup Repair could not repair your PC". It directed me to SrtTrail.txt, where the only detected error was "hal.dll is missing or corrupt". The mobo manual lists 78 as "ACPI Core Initialisation".
Restarted the PC, got past 78 code, everything working as normal. Played some games for a while with no problems. Switched the PC off and went to bed.
Got up today, started up the PC, same deal. Hangs at debug 78, then BSOD. However, not a Startup Repair BSOD this time, just the "your PC ran into some problems and needs to restart". Restarted, got past BSOD and everything working fine again.
Once I get past the initial BSOD, I can restart over and over with no problems. The mobo shows the 78 code every time, but it flashes for a split second before moving on to A0 (all good). I can also shut down/start up the PC over and over with no BSOD. So it seems like whatever is happening, only happens when the PC has been off for a while and, once I get past the initial problem, it's fixed?
Can anyone suggest root cause / troubleshooting? Because this problem only seems to present itself when the PC has been off for a while, my troubleshooting has been limited. What I have tried is;

EDIT #2 (27/12): After the below troubleshooting, the PC booted today with no issues. Straight to A0, straight into Windows log-in screen.
EDIT #3 (28/12): Return of the BSOD. Only difference between today and yesterday is that today I booted the PC up while the monitors were switched off. Taking this a potential cause and testing.
EDIT #4 (30/12): Switched PC on around 13:00, monitors on, all OK. Turned it off immediately to go out, came back at 16:30, monitors on, got the BSOD. "It looks like Windows didn't load correctly". Restarted PC, all OK. Further troubleshooting below (in order).

- Run MemTest, all OK.
- Run Intel CPU Diagnostic, all OK.
- Checked all physical connections and seating, all OK. (Surely not a connection/seating issue if I can use the PC normally once getting past initial BSOD?)
- Reinstalled iCUE, forced update for all connected devices.
- Disabled "start on system startup" in iCUE.

- Checked Fast Startup is disabled. Already off prior to crashes.
- "SFC /scannow" command run in Powershell. Corrupted files found and repaired.
- "Repair-WindowsImage -Online -RestoreHealth" command run in Powershell. Image healthy.

- Audio (Realtek) drivers updated.
- Mouse and keyboard reinstalled. Logitech GHUB uninstalled and removed from registry.
- GIGABYTE APP Center uninstalled and removed from registry.
- Run "SFC /scannow" again. No corrupted files found this time.
- Chkdsk run on both boot drive and secondary drive. No issues found.
- Checked CPU and RAM voltages in CPU-Z. Maybe useless info, but thought it best to check anyway.
- Bugcheck was 0x018 REFERENCE_BY_POINTER. Looked through crash dump in WinDbg, it seems to point to "NETIO.SYS" as the cause.
- LAN drivers updated to latest version. (^)
- BIOS updated. AMI F9 > F10g. BIOS image created and saved to USB, should I need to go back. I also have the 2nd BIOS which has never been touched since I built the PC.
