Question PC not turning ON

[AMD USER]

My PC is not turning on when I press the Power button on the CASE,
I saw few videos, related to this problem, where the suggestion I received was to

1. Try installing a NEW CMOS battery
2. Check if PSU is working by Paper Clip/stapler pin method.

I tried both of those suggestion, I got a New CMOS battery, removed the pre installed CMOS battery from the motherboard, installed the new one, Then tried switchingON the pc. Still it didn't turn ON.
I removed the entire PSU unit from the CPU CASE, and tested it using Paper CLip method. Since I couldn't get a Paper clip I tried it with Stapler pin, The fans in the PSU started spinning, I think that implies that PSU is perfectly fine.

Now I am confused what might be the problem with my PC.
I even removed my GPU and connected the monitor with Motherboard's display port, still no response,
Yet the RGB components in the Motherboard(ASUS EX 320 GAMING) Glows, when I switch on the Power plug.

My PC is barely a year old.
This is my PC config
AMD Ryzen 3 2200G( disable the VEGA 8 onboard graphics)
Asus Ex 320 Gaming motherboard
Gskill RAM 8GB(1 X 8)
Corsair VS 550
Zotac Geforce GTX 1050Ti
BIOS is latest.

Sunshine came at 3 pm, I kept my PC in sunshine till 4 pm, then brought it into the home, plugged in, pressed the power button on the PC case, it worked.

But date is right, but the time is totally wrong, it shows 2:52 but the time is 16:20, I never touched CMOS, I have no idea why time changes.

That could indicate a faulty mobo. The CMOS/RTC chip is also related to the power-on low-level details. If that is screwing up, it could indicate problems with that group of circuitry.

Yesterday night before going to sleep, I kept my PC in sleep mode, When I woke up the PC power button was blinking as it should when it is in a SLEEP MODE, but power(electricity) in my home went off, for 10-15 minutes, but after the electricity came back, I immediately didn't switch on the PC as I was held up in other work, but I tried switching ON the power button in PC case after maybe an hour, It didn't switch ON, There was no Rain, even the climate was not too humid,

After that immediately I removed the side covers of the PC and took it outside to keep it in Sunshine, Now currently at this moment PC is in the sunshine, I will report if PC starts or stops after bringing from sunshine.@DrMrLordX @VirtualLarry @Muadib @Markfw @DooKey

I brought the PC into the home after 40 minutes, there was good strong sunshine, PC steel cabinet became too hot even to touch, I plugged in and pressed on the PC power button PC started, but again the time was wrong, I had to correct it.

Maybe a cold-bug? IP35/35e sometimes had one. What board is this?
Hmm, Asus Ex (A)320 Gaming.... maybe the board is just shot, at this point. The danger of simply replacing only the board, assuming that's the problem, is that if the PSU is bad, or damaged the board, it could do the same damage to the new replacement board.

So I vote to replace the board and the PSU, both, at once.

Or get someone to breadboard and part-swap with a replacement PSU, and the possibly even a replacement board, to try to narrow down the issue.

You've proven that the issue isn't strictly the rain.

Thanks, I will try that if possible.

But still, I can't understand how come the PC starts every single time after it is exposed to heat from the Sunshine, This alone makes me assume that there some problems related to cold and heat.

By the way, I just noticed that long before I kept my RAM frequency to 2666 Mhz but now it is in its default 2133Mhz, I didn't change it back to default, I don't know how that happened.
Also, I find time being changed every time after I start the PC after keeping it in the sunshine.

I turned off the PC before going to sleep yesterday(28th october 2019) around 11pm, on 29th october I woke up at 2:30am, tried to turn ON the PC, same problem has appeared again, there was no rain, but the climate was quite cold, still the Room in which PC is situated is not that cold,
Now I have to wait for the sunshine to appear, so that I may place the PC outside to start it.

Think you either need a new mobo or at least a new battery.

 

[DooKey]

Yep, pretty much where I am.

 

[AMD USER]

I have a spare CMOS battery, which I bought when this problem occurred very first time, during when I removed the inbuilt CMOS battery and inserted this CMOS battery nothing worked.

In this thread, I came across this suggestion
"My suggestion would be to start with a new replacement CMOS battery, apply some light oil lubricant to the whole outside of the battery, only need to apply a thin film of oil, and install/replace the CMOS coin battery on the motherboard. Of course, you will have to check/reset all your BIOS settings and reset the clock. The idea here is oil repels moisture and stops corrosion, thus humidity can not cause problems where the oil is applied."

I am going to remove the OLD CMOS battery smear some OIL over all of its outer regions and again place it back.
If still, the problem persists the same procedure of smearing oil on the SPARE CMOS, which I bought when this whole problem occurred.

Hope this will prevent any further problem.


But still please share your opinions and thoughts about WHY PC TURNS ON EVERY SINGLE TIME AFTER I PLACE IT IN SUNSHINE?

Try the oil.

WHY PC TURNS ON EVERY SINGLE TIME AFTER I PLACE IT IN SUNSHINE?

Maybe you have one of those new "green" PCs, and it needs to photo--synthesize? ^_^

Yesterday(29th October 2019) I started the PC by keeping it in Sunshine for 1 hour while going to sleep I choose sleep mode in the windows 10, there was heavy downpour through the night till early morning, there was power off(electricity shutdown), when I woke up in the morning again I was faced with the same problem, I tried the applying oil on the spare CMOS battery and replaced it with the inbuilt battery, and tried switching the PC on, It did not work, so today the whole day there is a heavy downpour, there was no sunshine.



If the motherboard is at fault, it should not start at all forever, right?

I tested the PSU with PSU tester, it worked well, it passed all the voltage test, So now PSU is not faulty here.

Please share your expertise and your thoughts, why PC starts when it is exposed to sunshine?

I would say either replace the mobo or replace mobo + PSU.

Do you have any idea why PC starts immediately after it is exposed to sunshine, please share your knowledge and experience, it would be really helpful.

 

[bluechris]

To me it seems there is a cold welding in the motherboard. I have seen this in very old mobos or general electronic devices, or a ready to die capasitor somewhere in the mobo or in psu. The reason it works after it heated is a sign of what i say above.
This is going to make you go nuts so replace them m8 to have peace of mind.

No. And I think it's time for you to stop fretting over it, especially if you keep having power interruptions. Otherwise I would just say leave the thing on all the time and be done with it. Or get used to using a hair drier to stsrt the thing up.

 

[AMD USER]

On 31 October 2019, there was no Rainy, sunshine was really good, I kept my PC 1 hour in the sunshine and brought it back into a home, plugged in, pressed the power button on the PC, IT STARTED.
But the RAM speed was reset to default (2133 MHZ) and the time was changed(lagging).

Currently, the CMOS present in the Mobo is the new CMOS over which I smeared the oil.

If that's the case, I might have to contact the manufacturer as the Motherboard has warranty, they could refurbish it or replace with a new one.

Yesterday( 31 October 2019) before going to sleep, I switched my PC to sleep mode in windows 10, The power button on the PC case was blinking, even after I woke up in the morning (1 November 2019) the power button on the PC case was blinking, I thought everything was fine, but when I tried to wake up the PC,
by pressing various keys on the keyboard,
clicking mouse,
pressing the power button on the PC case( the power button light was blinking ),
holding the power button for 5 seconds,

Nothing happened, but the LED light in the mouse was glowing,
The PC did not start from sleep mode, but just the power button light on the PC kept blinking,

I switched OFF the power plug switch and again switched it ON, then tried to start the PC as usual, the same problem which has been happening all these days came back, no response, I kept my PC in the sunshine for one and half hour maybe, then brought it into home, plugged in, pressed the power button on the PC case, It started immediately.

But the time in the windows was changed.

 

[AMD USER]

Yesterday night(1st October 2019), I turned off my pc before going to sleep, again when I woke the next morning (2nd October 2010) the very same problem appeared again, there is no evidence of any rain, I kept the PC in sunshine for hour and brought it into home, plugged in, pressed the power button on the case, IT STARTED without any issue.

This happens every single time, When I keep my PC in the sunshine for an hour or longer, it starts immediately without any issue, The simple logic which I can speculate is there must be something damp in the motherboard which heats up and loses its dampness when I place it in the sunshine,
My idea is what if I place the PC in the sunshine(with side covers removed) for an entire day till the sunsets so that it might remove all the dampness, I never heard of PC parts being damaged from sunshine.

How much damage can it do to have a PC in direct sunlight for several hours each day?

I've got a pretty cramped room with a PC in it, and so I can't really place the PC anywhere else. The PC happens to be in direct sunlight, so I assume it can reach temperatures of 40 C even when it is off. I actually placed a shoebox right on top of it for a few weeks to see what kind of damage...

I believe you have a cold solder joint and it is expanding enough to make contact when you heat it up in the sun. Whether that solder joint is in the motherboard or PSU I can't say. Could be either.

Thank you very much for your valuable response, the cold solder might be the actual problem.

Now I have to guess whether the cold solder is in PSU or Motherboard, I am going to guess the cold solder might be in Motherboard, as PSU passed the paper clip test and the PSU tester's voltage test.

I agree on the cold solder. And the mem reset and time reset also indicate the motherboard is not retaining bios settings, and you have a new battery, so that seems like motherboard.

Usually whenever I want to start my PC, I used to take the entire PC cabinet with everything intact(just the side covers of the PC cabinets would be removed), outside to let the sunshine fall all over the PC, so that it might get heated up for an hour and I can use my PC.

But today, I did something different to specifically find out where the REAL problem is, is it the motherboard or the PSU.

So what I did was, I completely removed the PSU from the PC cabinet disconnected the PSU from the Motherboard.

I just kept the PSU outside in the sunshine, for an hour, Then brought into home and connected it to the Motherboard, pressed the POWER BUTTON on the PC CASE, I got no response, I switched OFF the main supply, and switched it ON, Again I tried to switch on the PC, by pressing the POWER BUTTON on the PC CASE. TO MY SURPRISE, IT STARTED.

Does this mean that Motherboard is perfectly fine, but the real faulty one is the PSU???
Anyhow, tomorrow or day after tomorrow, I am not going to keep the PSU in the sunshine rather the PC CABINET with motherboard mounted into it in the sunshine.
To find out exactly what is the faulty one here.

Don't think you've got to mention that many people in one go.

PSU's are cheap. Much much much cheaper than time tinkering. Low tech testing devices can miss marginality issues. IMHO it's much better to test with a redundant part(s) that you have high confidence in.
