Hello

I´ve been having a persistent issue lately

I had a gpu light ever recently swapping gpu and motherboard

First replaced the motherboard and the issue persisted

then replaced the gpu and it persisted

Replaced psu and ssd as well and it persisted

i mean , my ram was already tested in several software tests and my cpu just works as well

this doesn´t always happen , randomly the pc will hang in the vga light in the post process

the only things left are my cpu , ram , case usb hub and peripherals i think

i don´t know the root cause of this anymore

so the question is , can my cpu , ram or usb hub cause the pc to hang on the post process ( vga light ) ?

i have my pc connected to a monitor and a tv ( display port for monitor and hdmi cable for tv)

Everything works flawlessly when the pc boots ( most of the time )

I plug my pc on a line filter ( quality one )

My peripherals are : logitech g305 , hs65 corsair surround , redragon dragonborn keyboard , orico bluetooth dongle ( i suspect this dongle as well )

i mean it doesn´t make sense at all ( unless my cpu is busted or my ram but both are well tested , no crashes when the pc is on )

thanks

I wouldn't think so for the USB hub, but it is possible I suppose.

What are your system specs? Have you tried a BIOS update? Also, it is possible that it has something to do with the HDMI going to your TV, I have heard of some weird issues with HDMI and even DP.

When you have issues it is standard procedure to disconnect everything not strictly necessary and go from there.
This is the approach I'd also take, if it can be recreated consistently enough (and not like a once a month type thing). Just strip it down to minimal components (even run sans GPU), and then keep adding items one at a time until the problem crops up again.

Also, check that you're running the latest BIOS. What board/processor is being used? How many sticks of RAM? Is XMP/DOCP enabled?

hey guys just removed the bt dongle and the usb 3.0 port ( only the 3.0 , the 2.0 still present )

but yes , it will randomly crash in the vga light

is it possible my ram or cpu to cause this ? despite it working ok when it boots ? ( most of the time )

i´m wondering if i should get a am5 kit ( b650m tuf and a 7600 , black friday prices are a good )

the 7600 is pretty much equivalent to the 5700x3d ( in some cases it will even beat it )

but i´m upset to spend and not solve the issue

can it be really my corsair headset ? even if it turns out to be the issue , i don´t know corsair would proceed with the warranty

thanks

I think you need to be very systematic. Start with the bare minimum stuff, then slowly start adding back items until it won't boot. Is this is a completely new build or is this something that started to happen out of the blue?

What is the hardware configuration you have right now? (CPU, board, how many RAM stocks and what speed and size, what GPU, what CPU cooler)

too bad that this is very hard to reproduce

out of nowhere it will refuse to boot with the white vga light

i know that with the monitor off it will show the vga light ( but it will still boot ) but in my case it refuses to post completely ( no light from the keyboard when this happens )

my cpu cooler is a ag620 with the rgb properly connected ( i also use 3 case fans , directly plugged into the mobo )

it can´t be my ssd as i´ve already replaced it for another one

it started like this , had a tuf b550m , 4x8 3200 ( not any oc ) and one 4070 windforce ( in my previous case )

then i swapped case to fit a mpg b550 , got a 4070 eagle ( sold my windforce for a good price and bought the eagle )

then it started , thought it was the gpu at first , rmaed in the store and bought a 4070 super

then it persisted , then i´ve swapped psu ( core reactor 650w ) and it persisted , then i´ve swapped mobo and it persisted

maybe the case should i look for ? i just can´t get over when the pc boots ( most of the time ) it works flawlessly

i would expect like crashes or something but no

is one mice ( g305 logitech ) , 1 keyboard ( redragon dragonborn switch brown ) and 1 headset ( corsair hs65 surround ) too much for the motherboard ? they all are usb

is it possible for it to crash 2 motherboards at the boot process and stop the vga light ? could it be really one of my peripherals that causes it ? sorry for too much questions , sometimes i don´t have much time to troubleshoot extensively due to work etc

i don´t know what else to look for , maybe really my cpu and ram are busted ? cpu : 5700x3d and 4x8 3200 ram ( not any oc )

i´m sorry this is very upsetting , seems almost impossible to solve

would a short always stop at the vga light ? or something else that i should look for ? thanks

You can try memtesting to check your RAM for errors. Also, what BIOS are you on? Sometimes BIOS updates can help with issues like these, where a motherboard is slow to POST or has issues with it.

unfortunately the ram was already tested and latest bios as well

do you think is there a possibility of the mice , keyboard or headset cause it ?

4 sticks at 3200? Is this a quad kit or did you combine RAM kits? I'd try just doing 2 sticks in the appropriate slots and see what happens.

For some Ryzen 5 5xxx series, when you start to increase beyond 2 sticks, the max speed officially supported drops to around 2933.

yes , 4x 3200

i´ve tested the ram in memtest at this speed and it passed

i´m worried about usb devices , could my working devices causes hang on post ?

this ram worked a long time at this speed but who knows

thanks

it is just hard to believe , it first started at the previous gpu , replaced and it persisted

replaced mobo and persisted

replaced psu and it still persisted

also replaced sata ssd for a m2 and it persisted

only things left are cpu and ram ( and maybe my usb devices that crash my pc ) ?

thanks

So if I understand everything correctly, this is a new problem on an older system. If that's the case, what changes were made recently?

And yes, if you're afraid it's some USB thing, just stick to the basics for now: keyboard and mouse plugged directly in. Use the audio jack for headphones. Be systematic in adding stuff back.

Edit:
You really need to start at the very basic steps. I don't think you should just discount the diagnostic steps because something passed a test. You've been replacing stuff very hodgepodge, so it can be difficult to isolate the root cause.

i´m mostly upset about the corsair headset , pretty much expensive to replace it and corsair will probably deny the rma

i mean , all my usb devices work flawlessly

well , pc can be a pita sometimes

i plug my pc in a quality line filter , can it cause hang on post ?

this is seeming virtually impossible to solve as everything works but randomly the pc refuses to post at the vga light

i would expect pc crash or usb devices malfunction but no

my kit is also different from each other ( they are all 4x 3200 but different models )

would a ram instability just crash at startup and works fine once the pc booted ? thanks

So to sum things up clearly:

You had issues with POSTing, but only since you swapped both a motherboard and a GPU. The current specs are:

Ryzen 5 5700X3d
TUF B550M Motherboard (latest BIOS is 3611)
4x8GB DDR4 3200 - not a quad kit.
4070 Super
650W PSU
Some sort of SSD
And a bunch of USB peripherals

-----

Some basic steps to take at this point since you've done all this swapping around:

1) Reseat the processor. Ensure that there is the right amount of paste between the processor and the heatsink
2) Reseat the memory - Start with only 2 sticks of RAM, just for the diagnostics process. We're trying to rule stuff out. You could probably also ensure that XMP is turned on so it is actually running at 3200 MHz
3) Reseat the GPU; if it has the 12Vhpwr connector, ensure it is fully seated.
4) Make sure all your PSU cables are plugged in properly (CPU, motherboard, GPU...)
5) Then start with the bare minimum number of peripherals - keyboard and mouse, plug them directly into the motherboard's IO

Then you start the power cycling to see if will POST continuously. If you don't get a problem, add back an additional item (maybe fill the RAM slots) - repeat the cycling. Keep doing this until you hit the problem item.

Yes, that can cause a problem. Different chips don't always play nicely, even if they are "the same". That's why you should start your testing with a single matched pair.

Also, this is for the 5800x3D and the 5700X, so maybe a little different for the 5700x3D, but you can see that with 4 1-rank sticks, the max official support is only DDR4-2933. Throw in 4 unmatched sticks, and you're really starting to roll the dice.

hmm i see it makes sense

will start with 2x sticks and mouse and keyboard only

do you think my case could be a potential issue ? i don´t think if i can mount it outside the case properly

also , is it bad to continuosly turn on / off the pc ?

thanks

I don't think the case is going to inherently be a problem. It's also not bad to turn on and off the computer.

Just make sure the 2 sticks you start with follow the motherboard's guidance for 2-stick installation, and make sure the sticks are from the same original kit.

hmm i see

sorry being insistent and questioning once more , i will 100% do these steps but is there some damage from it being stuck at the vga light ? in the event of it being a short i mean ( if it is a short tbh )

i´m from brazil , i use a quality line filter ( the best one from brazil , the model is iclamper5 )

i never had my pc shutting off or the line filter shutting off but is there still a chance for the line filter to cause it maybe ?

will try these steps and report back

thanks

also one detail , always used the usb devices on 2.0 ports while on the msi mobo

on the asus i use mouse and keyboard on usb 2.0 ports and the headset on a 3.0 port ( the asus one has only 2 2.0 ports )

the problem happened with both motherboard being on the latest bioses

i will swap display cables , not sure if it can contribute to the issue

hey guys sorry for a torrent of questions but i recently installed a speaker on the mobo , would it still falsely input the vga light or maybe input the correct error ?

thanks

There is always a chance, but that seems extremely remote, especially if you were having a POST issue. I think if there was a root power issue, you'd see generally instability after booting, or it just wouldn't boot at all.

I'm not convinced it's a USB thing, and I don't think a specific display cable would cause an issue either. The computer should boot without any display cables connected (though, I'd keep one connected, just so you have some video output).

If you hear a beep code, post it here. You may also be able to google it to see what it means, or if it means something different than the error lights on the board.

Also, this is a stupid question, but you have the GPU plugged into the slot closest to the processor, right?

yes , both mobos the gpu was on the upper slot

if you need any more information i can provide please let me know

i´m having this issue for a long time and don´t know what else to chase

it is weird that it is mistakenly pointing vga light , which clearly is not ( can´t have gotten 2 damaged gpus )

i mean the gpu is not damaged at all , since it works pretty well

no component was ever passed through a extreme temp as well

it is weird to suspect the ram since it was pretty much ok this whole time but i know it can happen

i got one short beep on normal boots ( it hasn´t happened since i´ve plugged the speaker ) but this just means a normal boot in the asus site

thanks
