Windows 10 restarts intermittently - Please help!

[Bateman1950x]

Hi,

My Windows 10 desktop reboots on its own 2-3 times a day and does NOT write any *.dmp files even though I enabled crash/memory dump settings. (there's 60GB+ space on C: drive). This desktop has been 24x7 ON for last 5 years (there's no dust inside it) and reboots only when monthly updates occur.

 

The Event viewer shows "the system has rebooted without cleanly shutting down first. this error could be caused if the system stopped responding, crashed, or lost power unexpectedly.". I did not install any software/updates/drivers in last 1 week (problem started 3 days ago).

 

Please advise, TIA

What are the system specifications???

 

Power supply?

Have you witnessed one of these restarts? Is it a proper windows restart or sudden black screen followed by BIOS Splash?

 

This could be several things but a common culprit could be failing PSU. Given how you've used the computer for the last 5 years this isn't out of the question. Do you have spare hardware components you could swap in for testing?

Thank you both!
I think It's Proper windows restart but not sure as I don't sit in front of it.

 

It's HP elitedesk 800 G1 (old one but working great with SSDs + 16GB RAM etc.)

 

no standby machine to replace parts unfortunately

if its this one https://support.hp.com/us-en/document/c03808397 you may be out of luck now..... last support is quoted as windows 8 pro 64-bit

 

- i know you said you didnt do any updates, but did windows 10 do any updates automatically?

- do you know if your HDD are running in MBR mode or GPT mode?

- do you know if you are running with secure boot and fast boot?

 

i ask the last 2 questions because i have 3 computers that refuse to run windows 10 in anything but MBR / Legacy boot mode with fast boot and secure boot turned off as well as leaving tpm2 turned off,  however i can have storage drives as GPT. 

- the oldest being a gigabyte board for the AM3+ socket, 2 newest are Asus b450 boards running ryzen 5 chips.

 

my am3+ will only go as far as windows 10 version 2004

the 2 ryzens are still accepting updates...
