PC random reboots

[FTJR]

I've noticed in the past week or two my pc randomly reboots, not just AH, but even when its idle, it did this 3 times in the last hour while trying to play AH. I dont believe its related to AH in particular.

I  read on the web that it could be my power source.  Is that a likely problem? I haven't changed anything (except a driver or two).

Thanks in advance. (ps im travelling will be unable to reply for a week or so).

I had a similar problem with my non-gaming PC.  It was a bad battery in my backup power supply.

Random reboots definitely sound like a power issue.

Could you please send us a DxDiag output attached (instructions here: https://www.youtube.com/watch?v=Ymvl5Xu-SIo&list=TL5VpZZ-VsJrvG2czTa5Zfvt-GqZntvBGkand also tell some other facts about your computer? Brand or self built, model of the power supply, age etc.

These are the worst kind of problems to have.  They can be power, or heat, hardware, or software related.  Nailing it down can take some time, or you can get lucky, right off the bat.

Most motherboards, today, have a monitor page in the BIOS where you can monitor the voltage levels of the power being supplied to the motherboard.  Start there.  All the voltage levels should be within +/- .2V or the optimal level and should be rock steady.

Let it sit there, for a few minutes (5 minutes is plenty), from a cold start, and watch the levels.

Listing the components here might tip off someone as well.

Good luck.

I had similar problems few years back, changing the PSU did the trick in my case (capacitors went bad or something like that). Also check if your computer holds correct date and time, if it does not, it could be a drained CMOS battery that causes problems.

You could check your reliability history to see if it captured any problems and identified the source (type reliability history into your windows search, and it should show up as a control panel option).

If you feel brave, you can peruse the "Event Viewer" in Windows to see if you see anything there.

It is located in the Control Panel, under Administrative Tools, or you can execute it in the Run box by typing, "eventvwr" and <ENTER>.

Thank you everyone for your replies. I looked at the event log, there was this error that reoccurred 10 times,  that closely resemble the reboot timings

My system while not a self build is done by a local supplier, and approximately 5 years old, im not even sure to start with the other stuff.


My DXDiag is attached.

Again thanks for the help

[Bizman]

Thanks for the DxDiag. A quick glimpse did not reveal any of the most obvious issues to my untrained eyes.

If you please could open the case and tell what it reads on the power supply unit. Brand, model and power can already tell a lot. If there's an UL code, including that could tell even more.

Bizman, thank you for taking the time to help, i've attached a photo of the side of my powersupply

[Bizman]

Thanks, sending an image was a clever move!

What I can tell so far: As the HardOCP review says, "the M12II-620Bronze is an older --- design, the build quality for this unit is generally quite good". Plus it should have a five year warranty which means the manufacturer believes it should still work despite of being a low budget model. Seasonic has a very good reputation in power supplies - which of course doesn't mean you couldn't get a rare lemon.

Searching by the Event Log message brought up this answer: https://answers.microsoft.com/en-us/windows/forum/windows_7-performance/event-id-2017-event-source-srv/9f8f74f3-1a5d-44f1-b7ce-3322d97d2a43?auth=1. Before doing anything, backup the Registry just in case. File-Export-Save. In other posts I found the Anti-virus wasn't mentioned, however I'd start with that especially if you're using one of the most intrusive ones.

Asterix suggested it could also be the CMOS battery. It certainly is worth the $1 to change.

Thanks again Bizman, I'll do that, and see how it goes.

Cheers.
