Pc restarting on it's own

[Ultra_]

First my PC specs:
Motherboard: MSI Z SERIES
GC: ZOTAC GTX 970
Processor : INTEL I5 4690
PSU: CORSAIR VS 650
RAM: VENGEANCE 8gb
HDD: 2X WDD 1TB
UPS: MICROTEK 1000V
MONITOR: AOC 24INCH

My PC shuts down then restarts several times during the day with a loud clicking noise from the ups.
I have already changed 3 ups starting from a small one to a big 1000v one.

Also, when I connect my CPU directly to mains it works fine but I am afraid it may damage my CPU because of power fluctuations in the home.

Now some people are saying it might be PSU but that is working fine with no issues that I can see.

There is one more PC in home that's an old dual core home desktop with very low specs and no GC. It also had same company ups and that works fine, so I don't know if ups manufacturer is the issue.

Please, any suggestions will be appreciated.

Does appear to be intermittent power losses.

Do you have a power strip or other surge protection/protector any where in the electrical connections?

What about the power outlet serving the UPS?

Or the electrical circuit containing the outlet?

Any other noted electrical problems in your home: lights flickering, breakers tripping, etc.?

Yes there are electrical problems in home like one light flickers all the time, no earthing in some sockets and to be honest the house is really old.
But the pc is connected to an outlet which has earthing.
Iam using belkin surge protector to connect the ups or the pc if ups is disconnected.

One more point i want to add is that today when i connected just the pc to surge protector which is connected to outlet and went outside, the pc did close once.
So what do you recommend?
Please, iam frustrated with this problem and wasting money.

The Corsair VS range are fairly low end units and gaming pc's need high quality PSU's, they put the psu under high load for long periods of time. My guess is a failing psu, unfortunately the only way to really be sure is trying another psu.

Ok, i checked many voltage readings on my pc from bios and softwares like +12v and all and they seem to be ok. Also, iam low on money so if you really think its PSU i will change it.

One more thing to be noted that sometimes even on heavy gaming the pc doesnt restart, but other times usually at night it does. So, it sometimes works for many hours without any restarting and sometimes it doesnt even work for 5 mins.

Plus, there is always a clicking sound from UPS when restarting happens.

 

[sizzling]

It only takes the voltage to go off for a fraction of a second for the pc to restart. I have not seen any software that can record this and store it, as soon as it happens its lost. Problem is I cannot be sure but the psu seems most likely to me.

Firstly, thank you for the replies.
Secondly, I got your point but why it doesn't restart during the day time, like sometimes it can work for 8 hours or more. It usually happens during late night like 12 or so and in early mornings. Also, why there is always huge clicking noise from UPS when it happens :/

I have no idea why at night, is it hotter or colder in the room at that time?

The clicking I have a theory. When a psu starts to fail its common that when a power loss happens the psu cannot be switched back on straight away. It might be the ups is struggling to get the psu to start up again. This is pure speculation, I suppose what I am saying is the clicking might not be related to the cause of the problem and is just a result of it.

Man i really hope someone else also replies before I make a decision cause iam really at a shortage of money.
Anyways which PSU do you recommend which can be reliable even if i buy a NVIDIA 2K card or new intel cpu in the future.

Also no, its neither hot nor cold. I mean nowadays it could be colder because its winters but it happens in summer aswell.

Try the UPS without the intervening surge protector.

The UPS should handle surges on its own.

And please remember that surge protection is cumulative. If your house is having electrical problems then the surge protection may be low or non-existent.

You may find or note something relevant to your situation.

I was using ups without the surge protector since last 2 years.
It was just 2 days back that i bought a surge protector and still no change.

 

[Ralston18]

Remove the surge protector.

You need to control the variables....

As for "late at night" maybe there is some heat build up that accumulates and triggers the failures.

However, if there are known home electrical problems those problems need to be addressed and resolved.

Perhaps those problems are stressing/destroying the Surge protection and/or UPS. Once the UPS is gone then the problem hits the PSU.

Otherwise you may find yourself continually throwing money into and at "defense".

So, what should i do brother? I cannot get rid of this house right now and electricians have said that this is an ok socket for the pc.
I mean is there some sort of ups or psu i should buy which can stop this problem or do you have any suggestions what i should do?

One more point i want to ask, I have an invertor in my home, should i use that for the pc

 

[Ralston18]

Invertor? No. Not without knowing what the problem truly is....

As for the electricians I would be somewhat concerned if all they did was tell you that one socket was "ok" for a PC.

If they did not resolve the house electrical problems to begin with then I would have some concerns about their faith in any given socket.

Look at it this way: When the UPS clicks it has likely detected a power loss and is trying to provide power as it should do.

Perhaps the UPS is reacting falsely. Due to some internal failure. Yet you have tried 3 UPS's.

So, trusting that all three did their jobs and provided power during outages then that would indicate that the computer via its PSU or motherboard had a problem.

That all said:

Are you able to take the computer somewhere else with a stable power supply? Connect PC directly to an outlet and work as normal to see if there are any restarts?

Really need to narrow down possible causes down via elimination.

My recommendation is to find someone who can truly look into, address, and fix any home related electrical issues.

That is the core issue/ first variable that needs to be eliminated.

Sorry bro, but there is no other place i can take my pc to work that too for long time.
Sometimes during summers low voltage happens due to which our AC also fried.

My father old PC works good though which doesnt even have branded parts and has really old and low specs,
So, should i try a new PSU ? Do you think it might help?

One more point, it didnt happen from the beginning. It happened when my father started using my pc 24 hours or more for his business purpose and then i used it for gaming. Since, then it started almost around 1.5 or 2 years back.

New PSU - only if you can truly determine that the existing PSU is the sole problem.

Heating and cooling is an enemy of electronics. Too many on and off cycles can be destructive.

Running for 24 hours plus may cause slow heat build up and cumulative damage. Gaming can make things even worse.

Nothing is made to last and your system may have reached some limits.

Or some component has degraded to the point where it no longer has any tolerance for an "out of spec" condition. E.g., power fluctuations.

Older equipment can and often does work longer and better. Why? Because there was a time when product sales relied on a product's ability to hold up and last.

Now the model is to engineer in EOL (End of Life) or otherwise make it easier for the consumer to break things beyond any self-repair opportunities. Without any incriminating blame to the manufacturer. (Will concede to being very cynical about such things.)

Maybe you have had a "perfect storm" of events. Any individual event would not have caused problems. But a group together did and continues to do so.

E.g. power problems, older equipment, constant use. No fault of your own doing per se and no criticism implied.

Eliminate as many issues as you can and mitigate other issues as best you can.

The power problems are of most concern and should be a priority.

Brother then what is my best bet to do? I mean no one can tell what exactly is wrong in home power. Yes there are some times when the voltage is too low that bulbs dim out. Apart from that what could be the immediate solution for this problem.

Or should I all together buy a new pc which i dont want to cause new GC and CPU are coming next year.

So, now should I buy a better PSU or UPS or what ? :/ Or you can think of any kind of thing which i can do which will make things good for atleast a year.

Regarding Power again, what do you thing could be faulty and how it should be fixed?

ALSO, should i start using an online ups which will act as a stabilizer as well as an uninterrupted power

So if no one else is helping, is the post closed ? :/

 

[Ralston18]

Not a matter per se of no one else helping nor has your post been closed.

My sense is that your electrical system is most likely the real issue. Maybe I have missed something. Some error of omission or commission on my part....

Would hope that someone would post in some other ideas and suggestions. Happens all the time in this forum and overall very beneficial.

And I certainly have no problems with other thoughts or suggestions that may be offered.

What makes me now wonder is that why is there no one who can "tell what exactly is wrong in home power".

Continually attempting to mask the problem with surge protectors, UPSs, invertors, etc., is only going to cost you more money and you are likely to end up with even more damaged electronics.

Have you called your electrical company? Report the voltage losses. They should be able to check the service up to your house. And, if necessary, make any necessary repairs. Or tell you that the problem is indeed on your side (usually after the power meter) and that you need a licensed electrician to come in and investigate.

Really appreciate that you are replying bro.
As far as the home goes, iam going to stay in that home for maybe 1 year or half and its been given to us by our relatives. We practically dont have any money for the maintenance of power problems and also no electricians here have that much knowledge to what exactly is happening.
So, my only solutions are :
A: I buy a good quality UPS with 1000 or more V
B: buy a new good quality PSU
C: If you have any suggestions for anything that i can buy which can stop this problem for at least sometime.

Also I tried UPS alone in other room and it still has clicking noise like its trying to switch to battery mode

Do you think a good quality APC smart UPS can subdue this problem ?

Lastly why no one else is replying to my post :/

 

[Ralston18]

If the home is having electrical problems then nothing you can do will really "subdue" the matter. May provide some interim appearance of doing so but eventually the problem is likely to get worse and/or still kill your solution along with other electronic devices being "protected".

As to why no one else has replied to your post that is not for me to say.

Hmm so apart from checking electrical issue you have no other solution. :/
Also, I'm sorry for -1 I was just checking how it works.
Thanks anyways guess I'll buy a UPS and then PSU to see if this resolved.
Plus I'll wait for some more suggestions

 

[Darkbreeze]

Now some people are saying it might be PSU but that is working fine with no issues that I can see.

Wrong. You ARE seeing the issues, you are just not willing to believe that the PSU is the cause of the issues you are seeing. The VS series power supplies from Corsair are not well built and do not use the best component selection internally. We see a very high rate of problems with these units and it's entirely believable that this is where your problem stems from.

Chances are good that the click you are hearing is the the breaker on the UPS being triggered due to a short or other problem in the power supply.

Considering the rest of your hardware is, relatively, high end, I'd highly recommend that you replace that PSU with a much higher quality unit and then get back to us on whether the problem remains.

Also, if you have power issues with your home or local wiring grid, it's definitely a good idea that you have it inspected by a licensed electrician to make sure there are no safety issues and just as importantly, you might want to consider purchasing and installing a line conditioner to assure that you are getting good clean power to the UPS and power supply.

You would first want to verify their are no other serious issues though such as a lack of a properly earthed circuit or reversed/faulty circuits anywhere.

Ok I'll change the PSU as per your recommendation. I'll come back once I buy it
Please, also tell which PSU ishould buy for future upgrades as well.

One more thing does anyone know why my surge protector light sometimes emmit dim light even when main switch is off

 

[Darkbreeze]

Well, despite what I said before I wouldn't just take my word for it. That was more of a "just because the computer turns on doesn't mean the power supply is ok" kind of statement. However, that is a poor model of PSU. Certainly there are much worse ones out there, but considering the demands of your hardware, it would not be surprising to find that it is in fact in some state of disrepair.

Before I replaced it though I'd probably want to at least test it at idle and under a load. Do you have or have access to a multimeter?

Also, what is the exact model number of your UPS.
