Question Can usb hub from computer case prevent the PC from posting ?

[mat95]

i´m also using a 90 degrees dp adapter ( since my monitor is against a wall ) and the dp cable supplied with the monitor (lg ultragear 24 144hz)

 

[mat95]

i don´t know if it is relationed but i´m using a cpu fan and rgb splitter ( provided by the cpu cooler , ag620)

3 case fans , 2 in the cha fans and one in the cpu opt

You Dont have any GPU sag do you?

not really , it is properly screwed

are 3 usb devices too much for it to handle ?

or maybe my line filter causes it ?

 

[mat95]

it is just hard to diagnose as it is persisting in both builds

You keep coming up with random and unlikely suspects.

This is going nowhere.

Test with the bare minimum configuration and report the results.

i´m sorry as i don´t have very much time to test

i know i can´t get a concrete answer and sorry being repetitive

it is because i don´t know if the line filter can ''short'' or whatever ( even the pc never turning off by itself etc )

or if there is too much usb current for the mobo to handle on 3 usb devices ( they all work properly as well )

just wanted some answers before removing stuff , as like i´ve said , i don´t have very much time and this is seeming very hard to reproduce / solve

thanks

You're spending way more time asking questions about random things than just starting from the bare minimum build and slowly adding pieces back in until the problem reproduces.

i´m asking because maybe if remove everything ( case , rams etc ) and the line filter or some working usb device could be the problem

I think most people here are skeptical that a single USB device would be causing this kind of issue. That's why we are recommending you start at the basics. It doesn't take that long to undo stuff.

And if you did think a USB device was causing an issue, the simplest thing to do would be to unplug all the USB devices except your mouse and keyboard. You could have easily determined by now if that altered the balance.

What do you mean by line filter? My guess is line conditioner to provide clean power sorta like a UPS battery backup??
What kind of PSU did you swap to? Was it used or new?
Can you get into BIOS/UEFI ?
Does that 4070 super use the 12 pin connector?
turn off/unplug power supply and hit the power button a couple times to discharge any capacitors and pull the battery out of the motherboard.
Put battery back into the motherboard and plug power supply back in.

While you are at it you should make sure you do not have any motherboard standoffs that are under the board or misaligned.

But very important to tell us what brand class and rating of the power supply you swapped in. Bought new or used?

Sounds like no VGA signal after post. If you can get into the BIOS turn off the fullscreen logo during post option. That should give you more information of what is happening, IF you can get into BIOS.

sorry giving a link but the line filter is this one ( pretty quality , like the best here in brazil )

i always get new parts , never used anything 2 hand

the new psu is a core reactor 650w ( good as well , better than the xpg pylon 650w )

when the pc posts everything is functional but when it crashes it will infinitely stay stuck / crashed at the vga light

i don´t know if there is something to do with the order it turns on ( like monitor first then pc )

but i always turned it on randomly before and it always worked ( sometimes the monitor first or tv first , whatever )

i can get the vga light but a normal post by removing both dp and hdmi cables ( under these circumstances it does boot and the vga light stays on but that is it )

but my problem is a pc failing to post really and being crashed at the vga light

i think we can exclude psu , mobo , gpu and storage at least ( swapped this all and it persisted )

i´m not ignoring that to reset the mobo with the cmos / battery because this behavior happened on 2 brand new mobos , psus , gpus , ssds

so we can 99.9% exclude psu , gpu , mobo and storage

that is why i suspect : keyboard , mice , headset peripherals , line filter , cpu , ram , display cables and the case

i say about usb devices since it is vga light -> then storage , usb peripherals ( the boot order )

it is crashing 1 light before , maybe it is not transitioning to the boot phase or it gets stuck before with the vga light

are 3 usb devices too much for it ? ( i use g305 mouse , redragon dragonborn keyboard and hs65 surround headset , nothing else )

sorry asking too much , i know i can´t get a 100% concrete answer but that is what i think it is causing maybe

You are using Dual monitors or just both HDMI and DP plugged into same monitor.

I had issue with DP taking forever to boot and display with my old graphic card, and old DP cable. HDMI would boot normally I could see the POST process then windows. The DP cable would take like 5 minutes to show windows, and I could not see BIOS at all.

 

[mat95]

one for each display , dp to monitor and hdmi to tv

I think you need to check motherboard standoffs, are both boards atx or was one an eatx?

That's just a Type 3 Surge Protection Device (SPD). It has a varistor (MOV), and a gas discharge tube device.

It appears it also includes a MCB (mini circuit breaker) type component.

Usual configuration is with the varistor between L and N and the gas discharge tube device connected to PE (Protective Earth / "Ground").

The varistor is between L and N (line and neutral). At normal voltages it has a high electrical resistance and does not conduct. When there is a voltage spike, it "opens up" and conducts between the L and N, limiting the voltage. This could trigger the included MCB (and/or) the MCB from your electrical panel. The varistor acts fast, but it has a small surge capcity. This functions even if the power outlet from your house does not have PE/ground.

The gas discharge tube device (GDT) normally is connected to the PE and normally does not conduct electricity. When there is a voltage surge, an electrical arc forms inside the GDT and then the circuit to PE closes. The energy is dissipated to PE/ground. This has a greater surge capacity, but acts slower than the varistor. This does nothing if the power outlet from your house lacks PE/ground.

For better voltage spike and surge protection, the house should also have a Type 2 SPD installed at the electrical panel and a Type 1 SPD installed at the building conection point to the power grid.


So outside of a voltage spike or surge, your "line filter" does nothing.

i will check it again , but my case is a drx70 and i´ve tried mpg b550 msi and the tuf b550 ( with the default case standoffs)

hmm i see

i don´t understand these terms very much but i guess it can´t be the source of the vga light right ? even if the protection is not 100%

thanks

 

[mat95]

unless i got 2 busted gpus but that just can´t be possible

Did you ever take the steps to start from the bare minimum of a system and work your way back up until the problem starts again?

 

[mat95]

yes but like i said before , i´m afraid like something simple may be causing it

like line filter , display cable etc

swapped my hdmi cable and display port as well

running 1 stick of ram

 

[Seba]

"Yes" and what was the result?

 

[mat95]

"Yes" and what was the result?

doesn´t happen so far but it is so rare to happen it is difficult to test

like it happens once in a month

 

[Seba]

You started this thread 10 days ago and you reported that it already happened several times since. So not "once in a month".

sorry it seems like 20 days honestly

it is not something very usual but it happens yes
