Windows 10: extremely frequent random reboots; cannot isolate the issue

Hi everyone. I hate to bother folks with my problem, but I've been experiencing unexpected Windows reboots for almost a month now and just can't figure out what the problem is. I'm really hoping some kind soul will help me out.

Problem: My PC will (seemingly) randomly reboot at different times. In some instances, it will reboot seconds or minutes after the previous reboot. Other times it might be hours. I never get a BSOD, just a full reboot back into the log-in screen. This behavior started after I installed Valorant video game for my son. I have no idea if it's related (and the game is now uninstalled) but that's the only thing that I can think of that changed around the time the problems started.

Attempted Fixes: Here is a partial list of things I've tried to fix it:
- run memtest86 - no errors found
- run chkdsk - no errors or problems found
- remove heatsync, apply thermal paste, reinstall
- remove and reinstall all RAM
- disconnect all peripherals except for mouse and keyboard
- turn off automatic reboot
- windows startup repair (this does not work)
- reinstalled windows over existing build
- monitor temperatures in real time (never rise over 35-30 C or so)
- download and install updated drivers for motherboard, chipset, LAN, etc from the Asus website

Notes: There are a TON of NOT LOADED items in my ntbtlog file specific to @CPU.inf,%intelppm.devicedesc%;Intel Processor

Windows 10 Home (Version 1909 - OS Build 18363.836)

Any help would be greatly appreciated. I have no yet tried a full reinstall of Windows, but I'm really trying to avoid that if at all possible. I have a decent amount of apps/programs that I'd prefer to not have to reinstall and configure.

Thanks!

:)

 

Random Reboots

I've had, as the title suggests, random reboots for the length of the time since I've built my computer (2 years roughly) and they're completely inexplicable.

It happens under no load, high load, watching movies, listening to music, playing games, browsing the web, sitting by itself in the room when the my sleeping monitor is even saying WTF?!

There aren't any Events to view other than the usual 0xC*D event when the service just shrugs at me.

Any thoughts or suggestions? Maybe someone has had the same problem before and it was just a loose molex connection? I'm baffled.

 

Windows random reboot

Hi jayewaah,

There are several reasons that computers do a random reboot such as overheating, third-party programs running on the background that is causing conflicts on the system or corrupted system files.

I'd like to know the following details so I can provide the appropriate troubleshooting steps to help resolve this concern:

• What is the make and model of your device?
• Were there any changes made prior to the issue?
• What antivirus program are you using?
• Was your device overheating the moment you play games?
• In which instance does the reboot occurs besides when playing games?
• Do you have a third-party antivirus program installed on your device?
• Do you have any third-party programs installed recently?

For initial troubleshooting, kindly follow these steps:

• Check if there are available updates for your device by clicking on the
  Start button, then select Settings >
  Update & security > Windows Update > Check for updates.
• Verify if there are drivers that are missing or needs update. follow the steps on
  Update drivers in Windows 10 article.
• Check if there are blockages inside your device's components that may lead to overheating. (cooling fan)
• Perform a clean boot on your device to isolate the issue. This will determine if there are third-party
  applications that is causing conflict on your system. This will also help you check if the performance will improve and if the reboot instances will stop.

Update us with the results.
