[Gabrielmoura]

I didnt run my pc for more than a week, after sometime when I press power button it keeps shutting off immediately after I power it on, then I clean my gpu and ram but it keeps shutting off, after sometime it starts, yesterday It was giving me the same problem, but this time when I press power button it shutting off , second time when i press power button again nothing happens , like no gpu , cpu and case fans running, after 1 hour pc starts running, Now today its giving me the same problem again turns on for a second , second time nothing happens, after 5 10 mints when I press power button it keeps shutting off for 1st time after second time nothing happens without ram and gpu same thing happens, I tried psu with paper clip case fans was running means psu is ok and sory for my bad english:/

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition.

What did you do when you cleaned the GPU and RAM?

Pc specs
Pro: core i5 9400f
GPU: Zotac gtx 1660
MB: MSI H310 PRO VDH
8gb 2666mhz ram
128gb ssd, 500gb hdd

I've installed windows 10 pro, and I cleaned GPU AND RAM pins with just eraser, pc was just 9-10months old

Paper clip test is only a very basic test.

PSU could be an issue.

Do you have a multimeter and know how to use it? Or know someone who does?

Do you have another known working PSU that you could swap in?

yes I have a friend who knows how to use multimeter, No i dont have any psu right now but tomorrow i will bring psu from my friend.
So it maybe psu problem not motherboard?

The symptoms suggest a PSU problem.

Overall, the objective is to prove or disprove that the PSU is the problem.

The next potential culprit could be the CPU - thermal shutdown perhaps. CPU may need to be pulled and new thermal paste applied.

Ok i will test it with another psu and then i will apply thermal on cpu, thanks for your replies

Now I'm pressing power button nothings happens at all

PSU test?

Power button: case or PSU?

PSU test?

Power button: case or PSU?

Yes I've tested ATX 24pins with miltimeter, they are all 5.2v or 6v,
I'm talking about case power button

No 3.3 volt or 12 volt measurements?

If the multimeter testing was done correctly and the measured voltages are accurate then the PSU has failed.

I've checked it with another psu, nothing happens , just dead pc Maybe its motherboard?

One thing just happened now, when I unplug cpu 8 pins connector , pc just starts, when I replug 8 pins connector same keeps shutting off immidiately

Two possibilities come to mind:

1) When plugged in the CPU gets power and immediately overheats and goes into thermal shutdown.

2) When plugged in the CPU connector is creating a short circuit somewhere.

Did you use the cables that came with the new PSU? What make and model PSU?

Does the following link present the User Manual for your motherboard?

https://www.manualslib.com/manual/1654569/Msi-H310m-Pro-Vh.html#manual

[Verify to be sure.]

Check the EZ Debug LEDs; Reference physically numbered Page 17. LED status?

Are you able to access BIOS; Reference physically numbered Page 18.

Read the applicable language pages (English = 1 - 20) to doublecheck all motherboard components, card and RAM seatings, cable connections and jumpers.

That was my friend psu idk which on he has
NO EZ led indication, and I cant even Acees to bios.
I've remove cpu from MB but I didnt unplug cpu power 8pins connector, and pc just starts, Maybe the cpu is dead

Are you swapping/removing components with live power to the computer?

Do not do that.

Try a new CMOS battery.

No I always unplug power cable first.
Ok I'm going to buy CMOS battery, but is there any chances of dead CPU?

I've tried with new CMOS battery, same thing happens, First time when I press case power button nothing happens , Then I remove CMOS battery(new) and after 3 4 mints when I press power button fans spins for half a second includig CPU fan and then shut down, only one time fan spins , second time nothing happens like there is no power.
Edit: I've noticed one more thing , when I press power button fan spins for a second and EZ dubug led indicates CPU

 

[Ralston18]

And a known working PSU did not resolve the problem - correct?

CPU problem or motherboard power to the CPU problem.

You must very carefully troubleshoot each component by installing replacing with working components or installing any given component from your computer into a known working computer.
