My PC does not turn on when needed (Very strange issue)

[anuhas]

Hi All,

I'm having a very strange issue with my machine,

When i try to turn On the machine it doesn't turn on, Motherboard lights does lit but the machine won't turn on

The strange thing is if i keep my machine connected to the power for about 4-5 hours then i would be able to turn on my machine,
Once the machine starts to boot it doesn't show any errors and even the OS loads as usual but one thing i did noticed was the time which is showing in windows is incorrect

Once the PC is on i can play games or do any work without any issues even i'm able to restart or shutdown and turn it back on as well

But the issue will come again if i remove the power from the machine and keep it unplugged for more than 2 hours, then it gives the same issue which it doesn't turn on immediately

My machine specs are:

AMD Ryzen 3600
ASUS prime X570- P
TEAMGROUP T-Force Vulcan TUF Gaming Alliance 16GB (2x8GB) 3200MHz
Gigabyte RX 580 GAMING 8G
Samsung 850evo SSD + 1TB Seagate HDD
Silverstone 650W PSU

I hope someone can help me on this

Try with a different PSU if possible.

Try with a different PSU if possible.

Tried but the result is same

the problem is can't identify the exact issue for this

when the machine is working all components works fine even i have done stress tests :/
as long as the machine is On its runs perfectly

Could be a bad Capacitor on the Motherboard, although yours might be all solid caps so shouldn't be affected.

yep could be the motherboard
anyway its a very strange issue :/

Cap issue(s) with so new motherboard would be bery uncommon. What was the another PSU you tried with?

Its a Seasonic Core GM 550

Btw
Lets think this as a PSU issue but does a faulty PSU can change the time in the motherboard?

If the machine gets turned on the time is changed
whats your idea on that

 

[lsevald]

Not keeping time? Tried swapping CMOS battery?

Not keeping time? Tried swapping CMOS battery?

That's what I thought as well but it's a new system.

 

[lsevald]

Misplaced clear CMOS jumper in clear position?

 

[anuhas]

That's what I thought as well but it's a new system.

Yep complete new system

Misplaced clear CMOS jumper in clear position?

Checked the CMOS battery
Checked the jumpers

Only the time is getting changed

BIOS settings doesn't change

Alright, so it's 99% sure that it's not a PSU issue.

Well Yes
Even tried with plugging directly to power and using a UPS as well

I always use UPS to protect the machine

So the problem should be in the Motherboard but the craziest thing is i didn't get a simple BSOD issue

Can keep the machine running all day, the only point that the machine gets failed to run is if i unplug the machine from power and keep it for about 2 hours then the issues comes again

Pick up a new CMOS battery and swap them out - CR2032, I think is the one. Depending on where you buy it, what brand and how many are in the package it really shouldn't cost more than $5.

Just because something is new, doesn't mean it's without faults. I've purchased batteries and out of the package they didn't work (they looked new, shiny and unused).

I had an old Dell motherboard do that due to a swollen cap, ran perfectly once it was going.
The time changing could be the battery but check the time zone is set correctly.

Might be just a bios issue , the X570 is a fairly new platform, so...
- Check if you are using the latest one (launch CPU-Z and check the bios version in the Mainboard tab, then go to

PRIME X570-P BIOS & FIRMWARE | Motherboards | ASUS Global

AMD AM4 motherboard with PCIe Gen 4 for ultra-high transfer speed, and ASUS OptiMem for improved memory overclocking

www.asus.com

and check if you got the latest one.

BTW as you said you have swapped the PSU and the problem is still there (so that rules out the PSU issue) and that your pc is doing fine in stress tests (that rules out the graphics card , the cpu and perhaps the motherboard cpu VRM.

Try to change PSU, loosen the motherboard screws, check all PCIe cards and memory modules are inserted correctly, and make sure the electric socket is grounded (3rd pin exists and working). Sometimes bad memory can cause that, but most cases bad PSU or motherboard.

The OP already tried another PSU (same thing, btw both psus are decent), and also mentioned that everything works fine under load. So the last thing that remains is the BIOS (especially because the problem happens at sistem startup). So bios update is the way to go i guess

BIOS doesn't work when the system is off

BIOS doesn't work when the system is off

It actually stays in standby, waiting for the user to click the power button (among other things). And of course the battery is providing the voltage for the bios memory (...there is no way that the battery can be dead, that thing came out just recently and even IF its dead then why does the bios keep the config data and just changing the time??)

I have had this issue before, change the CMOS battery and everything should be fine (hopefully).

Is the Mobo brand new or an open box item? I had few open box mobos that gave me similar headache even after changing the CMOS battery, chances are the board might be faulty too.

 

[micropage7]

have you tried unplug the 24 pins power and leave it a while then plug it back and test it again?

Hey Guys
Thanks for the suggestions

So F.Y.I the bios version is updated to the latest one + checked with multiples PSUs + removed the components re-plug but the issue was same

found another interesting finding on this

So yesterday i did plugged the machine to power in the morning and after keeping it for about 6 hours later in the afternoon i was able to turn on the machine back again so from that time onwards the machines was working without any issues and for the whole day and what i did was i played few games until midnight(Apex Legends, Farcry 5, NFS Payback)

There were no errors in the bios (except for the time change), no performance issues, no temp issues at all and i even did multiple restarts as well

In the night (around 12.00am midnight) before i went to sleep rather than shutting down the machine what i did was i put the machine into the sleep mode and I went to sleep
So today in the morning when i try to turn on the machine it doesn't turn on and it remains in the sleep mode
(tried pressing keyboard keys, mouse clicks, even pressing the power button)

I can clearly see that the machine is still under the sleep mode because the mouse lights are working , and my case power button also blinks stating that the machines is still on sleep mode

so what would be your ideas on this ?

have you tried unplug the 24 pins power and leave it a while then plug it back and test it again?

Yep
did with multiple PSU's

I have had this issue before, change the CMOS battery and everything should be fine (hopefully).

It's a brand new item
not an open box

what was the brand of the mobos?
Is it same as mine? ASUS?

The problem is only the time is changing
if there is a total loss from the CMOS battery then even the bios settings should get reset right? which i'm not having bios reset issues, Just the time

 

[Nike_486DX]

well it seems like a mobo issue then (might be faulty board and/or bios bug)
do you have another mobo to test?

Nope

no extra mobos
