Solved HWmonitor Voltage diagnosis (duno if values are correct)

[TVeblen]

You can do a basic test of a power supply under load using a multimeter.
You connect the multimeter to any spare connector coming out of the power supply with black and yellow wires. A molex connector works best - you can insert the probes directly into the molex connector pin sockets and hold them there with tape. The + goes on the yellow (12v) wire.

Then you power on the PC and observe the readings, as it starts up, once you get to the desktop, and then as you use the computer. You would want to play your game at highest settings.

The voltage should remain steady throughout, no dips or drops. A tiny 1/10 fluctuation is normal in most consumer multimeters.

A PC can shut down due to overcurrent voltage protection in the power supply, Any disruption in power flow from the power supply, CPU overheating, electrical failure on the motherboard - to name a few.

Dont think its overcurrent as it is occuring only during certain conditions .
CPU seems fine ... (even tested at 100% load)
And i changed motherboard , i thought it was failing .

As for voltage ingame i will give it a try , need to find a multimeter , and as ingame it lasts really little now before shutting down .

 

[TVeblen]

Yes, best to rule out the power supply first (or confirm a problem). Otherwise you are just "chasing your tail".

 

[Denisgsv]

Went for replacing the PSU , will try it tomorrow . So i can send back the CPU (hopefully ! )

If this also fails ... im getting a laptop

 

[TVeblen]

Ohhhh. No one ever has problems with laptops!:sarc:

Does the Desktop PC is grounded at the wall plug? What's about electrical fluctuations in your house...

Could be a cable that touching part of the PC case or something doing statics. Check all your cables are not bended/break and well enough protect from each others.

the first sentence , sorry i dont understand what does it mean :| its a usual wall plug , then i got the power bar in which i have attached all pc related stuff , its fixated under the table . Should have a surge protector within .

As for power fluctuations it seems fine now , tho i had likke 5-10 shutdowns during last year , was thinking if that could dmg the psu also .

When i talk about "Grounded" is that here i've got at home three cables output in the wall plug, One is grounded for protecting from electrical shocks. So the PC Case is also protected from Electrical statics/shocks and does protect you either.

A Surge protector is a good need in case of lighting thunders.

Two holes wall plugs are not Grounded to Earth...

The power bar it's self could also be a problem.
A normal power bar has little or no surge protection.
They normally have a 20 or 30amp circuit breaker.
Does this power bar have a part # we could Google.

What power supply are you getting?

Power being a problem , i thought about it , discarded the idea because when pc shuts down other stuff like (monitor Router etc) dont shut down , i mean the electricity still gets trough . But i guess swaping maybe worth it .
Ill ask my brother (im at work atm) if he can get a serial number or smthing .

Power supply i went for the best i could find AX760I corsair , was considering ax860 one , but decided i dont need it , 600 is recomended 760 is more then enough , and for now i will stick with 1 gpu .

one can only hope :|

For the grounding im afraid its only 2 , ill check it today also . (tho im in italy it can be also the second row second one )

 

[Denisgsv]

ok . Got an update it was the PSU ... Swaped , passed benchmark test ingame stayed for an hour no shutdowns . I ve got another problem tho a small buzz sound and a small freeze , less then a second , I think tho its not hw but a video card driver problem , I as told kept swaping 2 video cards and I think drivers messed up a bit , will uninstall clean register and reinstal correct one . Really happy I solved the shut downs . What you think about freezes and buzz sound ? Can It be as i said or there are other reasons ? Thanks

I would swap out the power bar. They can cause all kinds of problems including damaging a power supply.
I would never use one on anything relating to computers.
Suggest using a quality surge protector. A quality one will cost under a $100.00.
We can't hear the buzzing sound so I don't know how to help you their.

All computer systems need clean power coming into them.

 

[TVeblen]

Glad to hear it! (Power Supply issue)

Try your plan: completely uninstall the drivers, clean up any remnants (DriverSweeper is good for this), and then clean install the best driver fresh. See what that does.
I would go a step further: I would clean and install the driver with just one graphics card installed. Test that for a bit. If all is good then add the second card. It should install on the driver with minimal intervention.

 

[Layback Bear]

Good point TVeblen, one card at a time.

Using two cards that are not matched will also cause problems. Both cards should be the same exact video cards.

This site should be helpful.

recomend me a surge protector and ill buy it asap . Didn't considered one before , didn't think it may have consequences . As for drivers rlly hope that's the problem , cos 2 days ago didn't had this issue (( restoring the settings for example to one month ago would fix the drivers ? My system was clean also driver wise before I started swaping and experimenting

 

[Denisgsv]

btw i dont want to keep both gpu , i kept swaping to test troubleshooting to find the issue , i want to keep only the latest it was enough ,,only got the old one to make sure it wasnt the gpu .

 

[Layback Bear]

Their are thousands of them.
I like the under monitor ones. I like them because they are easy to get to. I don't have to crawl under the desk or the like.
When I shut down all the computers in the proper fashion I turn off the power using the power button on the surge protector.
That means their is no power going to my computers and anything plugged into my computers.

reinstalling the drrivers didnt helped with mini shutering or hows it called ... its liike "laggiing" sort of :|

rlly hoped it was about the drivers , no idea now tbh .... yesterday had kernel error no lags :|
I feel like most unlucky person ever

 

[BigTabs]

Aida64 is good with accuracy

 

[Denisgsv]

rreinstalled audioo video drivers , stilll have stutering ... cant find the problem :|
