Windows 10: Computer is randomly rebooting with no BSODs or indication of a crash

A couple of months ago I started experiencing random reboots without warning, they occur usually 1-2 times a day. There were no BSODs or any indications of a crash such as dump files that I'm aware of. In Event Viewer I get a lot of 6008 and 41 Event IDs for unexpected shutdowns and reboots "without cleanly shutting down first" but other than that nothing I could see was out of the ordinary.


I concluded that perhaps this was a hardware issue as many threads online seemed to indicate so I booted the PC in Safe Mode to see if the random reboots persisted. The PC ran in safe mode for 5 days straight and then 9 days straight in two separate tests with absolutely no reboots. In my attempt to fix the issue I have reset Windows and deleted all files, I reinstalled drivers one by one and thought I had fixed the issue as the reboots stopped for 4 or 5 days but a few days ago the random reboots started again. I thought for awhile I had pinpointed the issue as graphics driver problems so I completely uninstalled all graphics drivers and then installed the newest Nvidia driver but the reboots have persisted. My Windows installation is also completely up to date and I have recently updated my BIOS to the newest version. Any guidance in resolving this issue is very appreciated.

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

10 Crashing Randomly and During Updates and File Downloads

This is a re-post from here.

I have a Windows 10 PC that I run 24/7. I have Windows Updates disabled through the Group Policy Editor. I still perform updates manually every few days. Windows Defender updates work fine. Other Windows updates cause the PC to crash, no BSOD or anything, it just turns off. I've looked for 1074, 6006, and 6008 event log files to explain why and I haven't been able to find anything.

Other times the computer just randomly crashes and also sometimes when downloading files. The symptom is the same, I check on it and find it powered down or it just shuts off while I'm using it. It boots back up fine and I see no cause listed in the event logs.

I have been through the 3 tests suggested to me on the old thread. SMART looked good, memtest ran for 33 hours for 8 passes with no errors, and prime was run for 3 hours with no errors.

I think the next step was to run V2 Log collector, that data is attached.

Any help is appreciated.

Thanks,
Chris
