Windows 7: Computer is shutting down randomly

Computer is shutting down randomly

Hi there how are you all doing..

136 days ago I had this issue
computer randomly resetting itself

and found out it was my SSD that was failing so I replaced it and everything was good.

About a month ago my computer started shutting itself down out of nowhere.
Sometimes it would loop, very strange behavior.
I have a dual boot system with 2 Sata Hdd's. I thought that the culprit was one of the Hdd's (the one I use for Internet connections) so removed it.
The issue solved like for 1 or 2 days and then it came back once again.

I remember doing things like, resetting the BIOS via removing the battery.
and testing with another Power supply.

I abandoned troubleshooting due to work, now I am willing to start again.

Any thoughts greatly appreciated.
Thanks

It can be by CPU over temperature.
On BIOS, is the CPU temperature alarm enabled? Set it to 80C.
Is the CPU fan alarm enebled?
Do you have a hardware monitor? I use this Open Hardware Monitor - Core temp, fan speed and voltages in a free software gadget
Set to show one core at task bar.
Set it to start with windows.

Hi, thanks for reply.
I always check cpu temperature with CPUID.
it is always good

thanks

What temperature does CPUID tell you? And is that temperature at idle? Or under load?

Just my two cents worth I am assuming it is a Sandy Bridge build?? I would like to see the voltage rails on the PSU now I use this to find those and I know it is not a perfect program as many tell me but I have yet to fault it, and when I have cause to doubt the findings I use a digital multimeter to find out for definite. That I have done anyway in the past when checking out the HW Info software.
Having said that to let you know where I am coming from
Using HW Info
PART A:
You can test the volts on the PSU with HW Info HWiNFO - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/- (minimum - correct - maximum)
12v1 = 11.4 - 12 - 12.6v
12v2 = 11.4 - 12- 12.6v
5v = 4.75 5 - 5.25v
3.3v = 3.135 3 3.465v
-12v = -10.80 - -12 - -13.20v
+5VSB = 4.75 5 - 5.25v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
FOR OTHER COMPONENTS
PART B:
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

Now at least this will eliminate any possible cause from a faulty PSU which is so often overlooked when finding computer faults as when it goes south so does everything.

hey thanks man.

Maximun temperature under load is like 75 celcius or something. It is very good. I have a very nice fan

hi there. I do not think there will be time for doing this.
Last time I checked, it will inmediately shut down, sometimes it will not even boot but instead goes into a loop.
But I will try this and come back.

Yes it is sandy bridge

75C is high temperature, not critical. Did you check if the heat sink is dust free?
Did you overclock the CPU or memory? If you did, try to set to normal.

it is dust free. No overclocking
I am pretty sure this is not CPU overheating issues.

Thanks

Well I'm sure 75C is to hot. Not to the toaster stage but still to hot for a custom build for sure.
