My pc randomly restarts and sometimes doesnt boot back on. No sod

Question

This problem started like 4-5 days ago, first tought it was an overheating problem because i got once the temp warning. I cleaned the whole pc, changed themal paste even tho the temps were ok even before (90C cpu and 70C gpu in stressers). Reinstalled windows and did ddu afterwards. It “fixed it” for like 4-5 hours then it started again. Cant boot up the computer because after some time it will restart and not boot back in windows, what i use to do it remove the battery from o reset bios settings and remove the ssd to force into bios. Before this everything worked perfectly, no high temps, never mined on it, cleaned regularly.

My pc specs:

Motherboard: MSI A320M-A Pro Max

Rams: XPG D60G 16gb 3200mhz

Cpu: Ryzen 5 3600

Gpu: 1080 ti 11gb

Psu: njoy astro+ 650W

Storage: 500gb ssd XPG S20G

Answer 1

Hello,

Thank you for posting in Microsoft Community forum.

Based on the description, I understand your question is related to pc randomly restarts and sometimes doesn't boot back on.

Restart the computer, press and hold the F8 key as your computer restarts. The machine will show advanced boot options. Select Safe Mode to boot into Safe Mode, check if the issue disappears in Safe mode.

Overheating can cause this error. Make sure your CPU is not overheating by checking the temperatures using a tool like HWMonitor.

Make sure your power supply is providing enough power to your components. Consider change a new battery.

Make sure your BIOS settings are configured correctly for your hardware.

Have a nice day. 

Best Regards,

Molly

I had done this before, havent fixed it. I managed to go to a friend who has a pc and tested every hardware in order, it seems the cpu was dying or already dead. changed my cpu with my spare cpu and it works perfectly so far, thank you for your answer tough.

I know this a bit of an older thread, but maybe your issue is/was as mine

I was getting random restarts - zero explanation, and that is after COUNTLESS of Windows 11 and Windows 10 clean installs. I even ran Prime95 for hours, did Test Mem 5 for hours too, nothing...no instabilities, but still random restarts

I had Curve Optimizer set up on my 7950x3D, and then I put it to auto, to see if it helps. Still restarts. Randomly, while idling system

Today after another restart I went into Event Viewer > Windows Logs > System

Then I looked at all the error and when I saw a gap in time, since my computer restarted overnight. I saw a red error

The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000139 (0x0000000000000003, 0xfffff281cafda0f0, 0xfffff281cafda048, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: f621a7da-575d-4db5-ac75-954642ac54f5.

Which could be something with memory, but here is what it said to an error 3 seconds before:

The Secure Boot update failed to update a Secure Boot variable with error Secure Boot is not enabled on this machine.. For more information, please see https://go.microsoft.com/fwlink/?linkid=2169931

I went into BIOS and I was dumbfounded, indeed it had Secure boot to Custom, and running not in UEFI mode (Windows 10 and Windows 11 are UEFI systems), but running in Other OS (which is legacy operating systems)

In short, I switched it to UEFI, and set Secure Boot to Enabled or simply switch that option to "Secure Boot" depending on BIOS.

If your system does not boot, that means you might need to reinstall Windows, as sometimes even switching back to "No Secure Boot" can already do harm to OS, I had it done to me in the past (but not in this case).

It was a roll of a dice, as switching Secure Boot to on can also break the system.

The reason is you need to install your Windows system in option that you will use (a lot of times, but not all the time, depending on your motherboard).

It also explains why Windows 11 would sometimes refuse to install, and read "Your system is not supporting by installation" or something like that, when trying to clean install. Which led me to install Windows 10 to see if my restarts disappear.

I am not saying your CPU did not fail, but perhaps it is doing just fine, but you had Secure Boot option off, and not in UEFI but in Other OS.

If I didn't read that error, I would have no clue.

Best of luck.

If that CPU is working, sell it :D
