PC boots second time after a 30 second wait

[SM Phoo]

Hey people, a friend of mine is having a bit of an issue with his PC.

When he turns it on, the fans seem to start at full speeds, and he gets a pop up on his screen saying no signal.

 

The PC takes around 30 seconds and then the fans settle down, and then the PC boots up as normal.

The PC runs as normal once this process has done, but happens every time, on a restart or full shut down and turn on.

 

I've asked him to unplugged all connected cables apart from the screen, but does the same thing.

I'm on my way there now, but don't want to start unplugging cables etc if it's an easy fix.

 

He has a ryzen x3d CPU, Not sure which one, a 4080

 

Thanks in advance

Hi.

Sounds like it's memory training on every boot, which probably means the small battery on the mobo that keeps the settings stored is flat. Remove it, take it to a shop that sells button batteries, and get an identical replacement.

 

The memory training will happen one more time after replacing the battery.

 

If that does not work, your friend probably needs to replace his mobo.

[esCaPade1]

Well, maybe not replace, but decide to just put up with it, seeing as it does work. 

 

I do now wonder though - 30 secs ain't much. I think training takes a good bit longer than that.

 

Are there any internal peripherals that might be slowing things down, like PCIe cards, mechanical hard drives, or optical drives (CD/DVD/BR)?

Or USB devices? Like memory sticks?

Hey, thanks for your replies.

It's quite a new build so I would be shocked if the battery has died, but I guess weirder things happen.

 

I've restored his mobo defaults to see if that does anything, but no joy.

I've made absolute sure on another boot that nothing other than the monitors were plugged in.

 

I timed it myself, and from pressing power to showing a successful boot, it was 35 seconds, obviously not the end of the world, but would be nice if we could get to the bottom of it, more for peace of mind that it isn't a hardware issue.

 

As I described in opening post, as soon as we press power, the lights come on the fans, cooler, gpu etc, but all case fans go at high speeds, consistently, then when they finally slow down, the pc boots as normal.

 

As for internals, 2 M.2 drives, no HDDs, nothing, it's pretty bare bones apart from the standard stuff

is there anything in event viewer?

That entirely depends upon how long ago the mobo was first put in it's box at the factory.

Some boards (like mine) train memory at each boot unless you enable "Memory Context Restore" in BIOS

Else it could be that the RAM isn't really stable, what are memory clock and timings ?

 

[esCaPade1]

Check for BIOS updates - it seems the most likely thing to effect POST delays.

I guess the GPU could too, or RAM, as @PDifolco suggests, though that would be weird after clearing CMOS.

Well my BIOS default is with MCR off, maybe it's an Asus thing

This sounds like a candidate. My Asus AM5 board takes forever to boot unless I turn on MCR, then it is fine. It defaults to off on my board. With 64GB of ram it is about a minute to POST, and 10 seconds when on. Both should be shorter with smaller ram.

Couple of warnings, but no errors

Thank you, I will give that a go and update!

BIOS updated unfortunately, one of the things I suggested before going over

This PC has 64gb, but I will give this a go, sounds promising

Turning on MCR didn't work unfortunately

The RAM was overclocked using Expo-I I think it was, set to 6000mhz,

I've restored defaults, which sets it to auto if I remember correctly, but still doing the same

Did you let it boot twice to test? It may have needed to train one more time.

You means it still doesn't boot properly without Expo ?

[SM Phoo]

I'll mark this as fixed for now.

I took out all the ram, tried one stick, two stick, various combos. Sometimes it was quick, sometimes it was slow, sometimes it didn't post at all.

For whatever reason, it now seems to boot ok.

 

The weird and wonderful world of PC hardware.

Will probably be unlocking this tomorrow when it's back at it again,

But, than you all for your suggestions, it's always great seeing people trying to help!

Good old reseat 

Nice one!
