Trouble with 'spontaneous reboots' - literally crashes and reboots without prompts

Question

Hi folks!

Here's hoping I can find assistance with my trouble. For - at least - a couple of months now, my desktop PC starts rebooting seemingly at random. Sometimes while idle, sometimes while I'm in the middle of working on a MS Excel file, other times just after exiting a game. I'm a novice when it comes to IT, and while I have tried varied attempts at a fix, none worked.

My specs:

This system was built by a mate in Dec 2023, and it worked fine when I brought it home - for a while, then the Intel 14th-gen MB microcode bug hit. I had to send the chip away after months of my PC behaving like it was possessed. The chip was found to be faulty and I installed a new replacement sent by the seller. Everything worked fine and now it started to misbehave again.

At the moment:

*Windows update is paused, primarily because the last security kept failing to install and I kept getting the SR - spontaneous reboots

*No dedicated antivirus software, as Bitdefender seemed to excerbate the problem

*Sfc scannow and scan health turned up zero problem in safe mode.

I saved a few of the latest memory dumps in the hope of anyone more knowledgeable than me point out or at least sterr me in the direction of a fix. Please see below for the link:

Please don't hesitate to ask me anything question

Answer 1

Your minidump files just indicate memory (RAM) corruption no specific cause of the crashes is listed

1

The best option is to download the widely available free utility MemTest86, then run a full 4 pass scan with that to test your RAM for physical errors

If no RAM errors are found, to try to force Windows to show any faulting drivers, the best option would be to turn on Driver Verifier, let your PC crash 3 times, then you must turn off Driver Verifier, and finally, upload any newly created minidump files

Before you run Driver Verifier, please create a new System Restore Point

Note, if you have any difficulty getting into Windows with Driver Verifier enabled:

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

Go to Troubleshoot - Advanced Option - Startup Settings and click Restart

Upon restart, press 4 to enter Safe Mode

Open Command Prompt as Administrator and run these two commands, then restart your PC.

verifier /reset

verifier /bootmode resetonbootfail

Apologies for the lengthy pause, work is keeping me very busy!
It seemes Gigabyte Control Center (GCC) is the culprit, or at least a major factor, in the near-constant spontaneous reboots I experienced. I'm solely to blame, because I downloaded and installed the GCC, as well as the individual essential drivers. Possibly even more than one conflicts arised from this oversight.

I downloaded all the individual drivers from the Gigabyte website, and removed ALL traces of GCC - this included disabling the update setting in BIOS. After turning off the modem router, I uninstalled the current drivers and installed the newly downloaded drivers. Some were actually older versions than the existing ones.

After rebooting and turing on the internet, so far everything is fine. <Fingers crossed>

Cheers all!
