Program for logging CPU/MoBo temps

I've started having problems with my workhorse desktop. It will randomly reboot itself, and in the Windows event log, the message is "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

The strange thing is, it seems to happen during system idle, either when I am working on my laptop or away from the computer altogether. I've run multiple Malwarebytes scans, and nothing is picked up. So I am I am thinking temp issue. The machine itself is about 10 years old, but I have upgraded/replaced parts along the way (new SSD 3 years ago, a new PSU 18 months ago or so). CPU is Intel Core i5 4430 @ 3.00GHz, MoBo is ASUSTeK Z87-A (SOCKET 1150).

I have Speccy installed, and the temps look ok, but it doesn't do continuous logging. I'd like to get something to track the temps over time to see if there is any temp variance around the time of the reboots.

Have you checked the Windows system logs to see why it was shutting down?

I think (I know they used to) core temp and gpu-z can log temps

Depending on the board, there may be software you can download/run..I use ASUS/ROG boards and its built in

I have looked, and there is never an entry for the shutdown - just a series of events on the reboot. One of those events during the reboot is noted as critical level from kernal-power that reads "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 just want to rule out a heat issue. I can see the CPU fan and PSU fan spinning, and I've never had heat issues before, but as I said the core of the system is 10 years old so I was thinking the heatsink/thermal paste might be causing an issue.

If it isn't a heat issue, I am thinking it is an issue with power. The PSU is roughly 2 years old, my UPS is probably 3 or 4 years old. My monitor (monitor is connected to both laptop and desktop via HDMI1 and HDMI2 inputs and I switch between them), nor my hardwired phone/answering machine which are both plugged into the UPS seem to have issues, so I am thinking it isn't the UPS.

Heat problems generally aren't tricky. You either have one or you don't.

Download and run Cinebench: LINK

Watch your temps. If they remain at a reasonable temperature during the test (feel free to loop it a few times) and then comes down reasonably quickly once the test ends, your cooling solution, including paste, is likely fine.

Assuming it's a hardware issue, my dart throw goes to a pending motherboard failure. But it's quite possible that a clean install of Windows might fix your problem.

Thanks. I'll download that this weekend and give it a shot.

I had another couple of random reboots yesterday after installing gpu-z, and those logs showed nothing out of the ordinary. I opened the case and blew/vacuumed out the fans and heat sink. Also unplugged and reset all of the cords going to the CPU.

Finally, I disconnected the USB cable going from the box to the UPS that allows software to monitor the UPS, as well as my external SSD that is used for weekly backups. So far so good. If it stays stable through tomorrow I'll start adding connections back.

All I can offer is maybe a RAM stick is going bad. Heat is a possibility but you should be seeing some high temps on the monitor programs.

Here's my recent problem:

My computer randomly started shut downs some time after I added some used RAM. I fixed the problem by turning off my hibernation/sleep.

For some reason, the PC would only have issues after coming out of sleep. I have not had the issue since changing this setting.

RAM going bad is a good suggestion as well.

With your mentioning you disconnected and reconnected your cables, that could be it as well. I had random instability issues about a year ago because my GPU power cable was failing. Took me a while to figure it out, because it was exhibiting the same behavior as a card with an unstable undervolt/overclock. I would maybe check all of the termination points if the cables to make sure the pins and everything look clean.
