PC Reboot+Shutdown

[BV2023]

Hello,

Starting a few weeks ago I started experiencing frequent and seemingly random crashes on my pc. At first it seemed as if this only occured while gaming, however now it will happen randomly on startup or if the PC left on idle. Now the PC will seemingly run fine for a few days and then the issues will begin anew. Occasionally upon the reset I noticed that some of my Usb devices/adapters would stop working as well. Following one of the posts I saw online I attempted to use Hwinfo32 to log the issue, and ran a prime95 test, smallest. I did this as a friend wondered if it were a CPU related issue, sure enough it was an instant crash. I attached the log in hopes that someone can help me read what exactly is happening, as I am relatively new to troubleshooting and am having a hard time understanding the results. 

Two errors I found on Event Viewer consistently are 

 

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.",

 

as well as 

"

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 1

The details view of this entry contains further information."

 

Things I have tried-

*Fresh install of windows with the latest drivers and bios.

*I was wondering if this was RAM related and ran a memtest86 with no errors on all of the passes. 

*Ensuring that all wires were properly connected.

 

Any help would be appreciated, thank you!

Prime95 is old and doesn’t test a bunch of functions.  It’s mostly good for checking heat problems and if you’re crashing in boot the only heat problem you could have is a bad mount and that would crash every time.  SOP for ransom crashes is do a memory test.  It will probably come back clean, but it’s one of those things they’re free and automatic but slow.  Set it up, run it, and go do something else.  You will want a few full runs.  Another thing that comes to mind is m.2 cards if you have any because they sometimes turn off usb.  Something would have to be flakey there though because sometime it seems to not happen.  If you boot drive is am m.2 and turns off usb ports with your motherboard that could I think possibly be the problem.  I might be missing something though which says that can’t be the problem.

Hello, thank you for your reply. By memory tests did you mean tests like memtest86, if so I will get on that right as I only did 1 test with 4 passes. I am currently not using any M.2 cards at the moment just 3 normal SSDs. I was wondering however if not RAM related if it could potentially be a PSU issue. Thank you again for your time!

Then you checked memory already.  There are folks who will run memtest, but not do a complete pass because the thing is so slow.  Hence the exposition.  There are two ways PSUs can be an issue: one is the traditional way in which not enough power is produced or there is too much flutter, or with ryzen2 or more or ampere or more you can get transient spikes which can trip OCP even if there is technically enough power.   With those the power just goes off.  Sometimes with an audible click.  You’ve got to start the machine again.

The solution for both is newer and/or larger power supplies.  In the second instance newer means atx3.1
