My computer randomly shuts down- is it my psu?

[AnnaFly]

Greetings.

 

@ Gooboo.

 

 Yes i suppose you will not get an answer quickly at the Dell's forum ....

 

I'll suggest to post your request directly to Microsof Answers ( or TechNet but this one is for the "Pro" users since a few years now  ... even if those "called "Pros" are  just "newbies"  sometime   ... ) .

 

When your computer started to "crash " ... you wrote "shut down "  ... but i suppose you mean "crash " in fact , right ?

Maybe your HWmonitor software may cause this " shut down " ... itself , the sofware checks a lot of things  ( by the sensors ) every 5 seconds or more ... and sometime this is enough to cause a "crash" .

 

 I suppose you are not familiar with the french language so i will just post the link to Microsoft Answers " US "  ... once there ( you must be logged to post a request , but if you use Windows 10 you already have a Microsoft account ... theorically ... ) post your request with a maximum of details (  about your hardaware ) and ask them "how " to use this software ... "Who Crashed " ... and tey will recommand you the whole procedure ( they need the report of this kind of "tool" to identify the source of your problem ... ) .

 

 I don't have my olders links on this machine ( when i was "working" there at Microsoft TecNet and Answers - Loukiana is my user's name there too .. ) so i' ll just post this one ... i hope is a "free" version (  but i'm not quiet sure ) :

Cheers.

 

PS: if you post your request at Microsoft, please let me know the link to your "topic" ok ?

I'm no more  "active" at Microsoft but i still go there to check some older topics ( especially to find some older links very useful) .

 

PPS ; a copy/past from the Bjornk 's post :

 

 

Supply [V]: Range (min. to max.) Your reading

 

+3.3 V: +3.135 V to +3.465 V ~2.8 V(*)

+5 V : +4.75 V to +5.25 V ~2.78 V(*)

+12 V : +11.40 V to +12.60 V ~10.9 V(*)

−12 V : –10.80 V to –13.20 V ~-8.9 V(*)

−5 V : –4.50 V to –5.50 V ~-8.9 V(*)
+5 V_SB: +4.75 V to +5.25 V ~2.8 V(*)

 

(*) Out of spec, although these readings may not be accurate at all.

 

Sure these readings are not accurate at all , a computer will probably never boot with such voltages ...

As others have said voltages are pretty odd. It may be the PSU, but it might also be a problem with one of the connected devices, or even cables in your system (make sure they are all attached properly), or the chip on the motherboard that reads these voltages is not functioning properly.

 

Also, is the power outlet properly grounded? This is the first thing you should check. Many years ago, a friend of mine needed some assistance for a very similar problem (random resets). Did what I could do, but couldn't find anything wrong with the PC. Later, it turned out that the power outlet wasn't grounded. -bjork

Yes I agree. Keep in mind that even if you moved to another section of the house and used a different outlet it might be your electrical system. I had a section on my old place where I wouldn't receive the proper amount of voltage. sometimes dropping to 80 volts instead of the regular 120. This wrecked havoc to my system or anything electrical that required larger amounts of electricity.

 

Bottom line it is time to have an certified computer tech have a look over your system before something gets hurt and cost you more money. That is my advise. You have done almost everything you can do. If you are by a store that will allow returns without restocking like Microcenter then get yourself say a 600 watt power supply (better one since -bjork thinks the model you are using aren't good. ) and try that one. The chances of a brand spanking new one giving you similar results is astronomical. If it don't and everything starts to work great. Keep the power supply . If not give it to a tech and explain all you tried to fix. It will help. I have many tech friends and trust me. Your info is invaluable. Still they will go through he process and testing to be sure.
