What is causing my pc to shut down randomly?

April 22, 2016 at 21:46:53
Specs: Windows 7 64 bit Home, Amd fx 4300 quad 3.8 ghz/ 16gb
PC shuts down randomly but I can't identify the issue. The time intervals seem random. I just got the gpu, psu, and ram only 2 months ago. The pc does not restart itself or give any visual cues beforehand or an error message. I tried checking temp but I see them at around 50-60C before a shutdown. I've cleaned out all the dust, fans are working, and it doesn't feel hot inside the case. Help would be very much appreciated.

Do you see any clues in the Event Viewer?

If a minidump was created, try to analyze with BlueScreenView tool

"The time intervals seem random. I just got the gpu, psu, and ram only 2 months ago"

Please post the make/models of your new hardware. Random shutdowns or reboots are often caused by the power supply - usually due to it being overloaded or because it's a cheap generic unit. Also, post the make/model & specs of the PSU you replaced.

Recheck the temps on HWmontor, it shows more temps than many other programs.

Post a list of all components including makes and models (or system make & model plus all added components), especially on the power supply and graphics card. Include details on all RAM installed as well.

You have to be a little bit crazy to keep you from going insane.

Instead of booting from your SSD, does the HDD have an OS on it you can boot from?
Or other standalone OS USD flash drive; linux, windows...

Remove what is not needed to run the system; Wireless, SSD/HDD. If you have an onboard GPU, remove the GPU and use the on-board

@sluc That is the only OS I have available to boot from. I try to save everything on the HDD, but the OS is on the SSD. If I were to remove the connection to the HDD, could that possibly negatively affect anything? (I am currently on the pc and its been on for 10mins despite it shutting down soon as desktop booted prior to this boot)

Trying to eliminate the SSD as a possible problem device. If you can boot from another device with windows or linux and see if the system keeps running.

I understand, but I have no other boot options. I did see on HWMonitor the cpu clocks at 3.9ghz and maxing at 4.1ghz. So I turned off cpu boost in BIOS and it seems to be helping now. I am running games to test it out but I wouldn't see why something like this would happen when I changed nothing to the system besides those parts. (I do not mess with BIOS and wouldn't want to OC)

Going to run a more intensive game to see how it runs. Temps are still ok and clocks are now 3818mhz instead of over 4k.

Edit: Nope, powered off with no warning or reboot while booting GTA V. Well, back to square one for me. I will be going to work in 2hrs so just a heads up if my responses are few and far between

If you haven't already done so, disable the auto-restart feature. That will allow a blue screen error message to be displayed & may help to troubleshoot the problem.

http://pcsupport.about.com/od/windo...

Have you tested the new RAM with memtest86 or memtest86+? Did you manually configure the memory settings in the BIOS?

You didn't say whether the 50-60C CPU temp was at idle or under load. If it's the loaded temp, it's fine; if it's the idle temp, it's too high...that would suggest a problem with your CPU cooler.

I doubt the new PSU is the problem but I don't know why it was upgraded? The Corsair 600W was more than enough for your setup. If it was because it lacked an 8-pin PCIe plug for the new graphics card, all you would have needed was a $5 adapter. In fact, I'd bet an adapter came with the card.

Idle is 9-19C for cpu 1min upon booting. Now at 29C after being on for 5-7mins idle but stable it seems. Going to try to run memtest

9C is only 48F. Is your computer in an unheated room?

No, I'm not sure why it put that as a min but it stabilized at 30-35C. Memtest is 75% complete no errors yet.

Off to work , so updates will come very slowly now.

Came back and memtest still didn't find errors so I exited and disabled the auto restart feature. When it powered down again there was still no message or screen pop-up, just keeps going from normal to instantly off.

The problem doesn't seem to occur in safe mode or regular boot. I need to boot by disabling driver signature enforcement. I'm unsure what all is affected but the graphics card is affected and seems the audio as well if I do not disable. But I did not update any drivers when the problem started occurring.
