Random PC crashing and turning off

[phillpower2]

No, crash dmps help us analyse what is causing the system to crash as in if it is software/driver as opposed to hardware related, if the system crashes, you look for a crash dmp, if there are any you upload it/them for us, if no crash dmp is available it suggests that any issue/s are hardware related which by the symptoms described and the HWMonitor and Speedfan screenshots provided I suspect to be the case as in overheating.

How does the computer behave now.

I have asked a couple of times how the computer is behaving since you post that as suggested you had restored the MBs optimized settings back in your reply #7 March 27th, please advise.

PC is behaving just the same as always, no changes just still crashing and randomly shutting down. I rechecked the minidump file there were still nothing there.

Suggests that it is hardware related then with overheating being the prime suspect.

Are you ok with working inside a computer.

Yeah I’m fine with that

The following checks require the computer case to be opened so take the following safety precautions, 1st, disconnect the power cord from the wall socket, press the power on button to get rid of any residual charge in the system, remove the side of the case, take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case.

Inspect the CPU cooling fan and heatsink, make sure that it is securely mounted atop of the CPU and that the cooling fan and heatsink are not clogged with dust.

Remove the video card, blow out the slot and re-seat the card securely, do the same with the memory sticks, clean all internal fans, if you use canned compressed air do not let any fan spin freely as this can damage them, use something like a clean lollipop stick to hold the fan still.

Ensure that all internal connections are secure and that there are no loose components, write down the PSU details (make and model) re-assemble the computer, boot up and see how it goes.

Just a cautionary note - if you do use canned compressed air do not upend the can as it is possible for fluid to be emitted and do not use a hoover or cleaning out dust, they create static that can damage the hardware.

I have done all as mentioned above and no change, I’ve had 3 random turn offs today. I do agree that heat is an issue but not all the time. I’ve encountered many times before when the pc will crash/instantly shut down when the pc has just been booted and is cool and low temperature.

The CPU will be so hot within a matter of seconds from boot that it would take your skin off should you touch the top of it, a computer does not need to be on long for it to overheat and if the MBs thermal sensor is doing it`s job correctly it will shut down the power straight away to prevent the CPU from frying.

Options are 1: Remove the CPU cooler, clean off and reapply the thermal paste. 2: Swap in a known good PSU that has an adequate power rating for testing purposes. 3: Remove the MB and do a barebones test on a large piece of cardboard, this in case there is a system short.

Let us know what you decide on first and we will post the required info.

Not heard back from you Ala Natur, do you still require assistance or is the issue now resolved, an update would be appreciated.
