Inconsistent POSTing on PC ( already replaced multiple parts)

[matpc]

yes it is always a black screen white the vga light stuck

i have a m2( replaced already)

gpu directly on the slot

i don´t know what else can be , maybe the line filter is bad ? note that when the PC boots i have literally 0 problems this is why it is tough to justify line filter , cpu or ram are bad

just tested on memtest86 again and it always passes ( all 14 tests )

i´m at loss right now , tired to troubleshoot these problems that come from other worlds , always the most difficult problems to solve

i´m tempted to buy 2x8 3200 ( same stick as i use 4 different sticks but they are all team group with slight differences)

it is the same model i mean , but some are newer and other are older ( in model , got all of them brand new )

it is just hard , i thought a ram error would point cpu , dram light at least

AFAIK, Getting stuck on "VGA" means the there's some issue 'handshaking' a PCIe device, not explicitly the video card.

'Had similar issue with a HDTV that's PSU failed and started dumping half-mains voltage to ground through the HDMI cable. IMO, Try a diff display and display cable.

-and, as friggin' dumb as it sounds, try booting the system up with no lights, phones, or other appliances/devices powered-on in the room/on the circuit.
I once worked IT at a company that bulk-purchased HDMI cables that would crash the connected PC from walking by (static) or using your phone nearby.
Also, I've been noticing cheap import LED lightbulbs both emitting and receiving interference to/from PCs . For example: If I turn off the LED lights, my WiFi and BT signals reliably gain strength and speed.

Sony were very prone to this atleast in 2013/14 when Triple Play Services ran on coax/hpna

Would the POSTing process ''react'' lets say if i remove a HDMI or DP cable in real time ? or the corresponding problematic device? or if the boot is already stuck i have to restart the PC ?

maybe if it happens again i could try removing some display cables to see if continues to POST?

Hey guys just tested memtest86 and memtest86+ again and no errors in the ram

one thing to note , i ran 4 loops ( 14 tests in the memtest86 ) but ran 10 (in memtest86+)

Is there more tests to do in memtest86+ or is it enough? at this point i´m almost sure it is either a usb device that crashes the mobo on startup or maybe some bad hdmi , dp cable

also one more question , is there a chance that the case hub can be problematic and cause this post issue ? both usb and usb 3.0 port works

 

[matpc]

one other detail also , sometimes it fails to POST completely where other times it will post but the VGA light will remain ON

and most of the time normal post , no lights remain

Go to a shop

Read it again.

You weren't following directions in this thread or the many others you've created, so the solution for your pc problems is to go to a shop and let them fix it for you, then you stop messing with it, and leave it alone.

Capiche/comprende.

 

[matpc]

I just wanted to try a precise shot , instead of keeping guessing what is the problem

I´m tempted to buy another dp/hdmi cable but not sure if it will change a thing

or my usb bluetooth dongle is really the culprit

i never had such complex issue

i wanted to know again please , if i get the error again , removing the problematic device will keep the motherboard posting or it will be forever stuck at the white light and a restart will still be required?

if i come across the light then let´s say i remove the bluetooth dongle ( if it is the problem ) would the PC continue posting?

It is complex because you are not following the suggestion to start from scratch and add components one at a time.

Ok i removed the bluetooth dongle by now

Sorry i´m just worried i may actually have a faulty cpu or ram ( ram already tested as well )

thanks

 

[Shrek]

Start from scratch...

it is also not good to remove the headset

i mean , i still use the computer to play some games etc and i need it to output audio

but anyways , just using mouse / kb and corsair headset ( all connected to the mobo , not the usb hub)

Start from scratch...

just mouse keyboard ?

 

[Shrek]

Just one drive

Pull all the cards, etc
use the CPU video (if there is any)

I am afraid you just don't get troubleshooting electronics, or maybe troubleshooting in general.

When it comes to troubleshooting and repairing electronics, 95% of the of time and effort is spent determining exactly which component is faulty. Just 5% goes into actually replacing the faulty part. This is exactly why most repair shops do not give free estimates.

@eidairaman1 and now @Shrek are correct. You don't follow the excellent advice given and apparently keep dinking with things and not making it better.

Have you tried breadboarding it as suggested? Twice?​

Have you tried one stick of RAM at a time?​

Did you check for extra standoffs? Asked twice.​

Did you try the Reset switch as the Power switch option?​

Did you unplug extra drives and USB devices?​

Did you try a different slot?​

Those are just suggestions from the first page of this thread - and as far as we know, you tried none of them. It seems only today you took the USB hub and dongle out, 4 days after removing extra USB devices was suggested.

I agree with eidairaman1 - you should take it to a shop. There is no shame in that. In there are advantages. For one, reputable shops typically provide a 30 day warranty and two, they are responsible for any collateral damage.

i didn´t mean to sound rude or stubborn

but the usb dongle was already removed since that day

i mean if it is worth to replace my display cables already

i wanted to try multiple solutions at once maybe ( not denying the ones suggested )

do not forget that is also very very hard to reproduce this problem , it happens like 1/50 times i turn on the pc

it is a silly problem i agree since rebooting always fixes it but who knows

the standoff was already checked ( using it )

about the GPU slot , not sure if worth trying ( since like i´ve said , gpu and mobo already replaced )

already removed unecessary usb devices since that day ( i can´t say it fixed since it is very hard to reproduce but will keep posted)

and regarding the case and breadboarding as well , would these be options if i were not getting power at all right ?

the posting process is stopping at the GPU , but the case always supply power to the components ( power and reset button always work as well )

but yes , it could remove the USB hub from the case

i also wanted to say sorry but i´m already very tired to troubleshoot

this behavior is like 2 months already with no solution ( and my dumb act to already replace the pc parts)

one more detail that i´ve noticed , when supplying power to USB ports when the pc is off , my bluetooth dongle used to be on 24/7 ( his blue light would remain lit )

i´ve removed the dongle since that day and stopped supplying power to usb ports

i´ve typed usb in the bios , to check if the computer is attempting to boot from a usb device maybe but i did not show anything

is it a more complex option maybe ? mobo is tuf b550m

but i´m wondering if supplying power 24/7 could crash the usb devices ( as well as the mobo )

 

[Bill_Bright]

FTR, I personally have not perceived any of your comments as "rude". Stubborn? Maybe. "Frustrating" that our advise is being ignored, or if tried, that we've received no or confusing feedback to that advise? Definitely.

the standoff was already checked ( using it )

I have no clue what "using it" means as that make no sense in this context. Note any extra standoff creates the potential for an electrical “short” in one or more circuits. The results range from "nothing" (everything works perfectly) to a wide assortment of odd problems, to "nothing" (as in nothing works at all ). To add to the confusion, these issues may be intermittent, depending on heat, expansion/contraction of materials, as well as continuity/resistance through the contact point. Therefore, you need to ensure the case only has an inserted standoff where there is a corresponding motherboard mounting hole.

Note the latest version of the ATX Form Factor standard hopes to eliminate these issues by dictating where case standoffs and motherboard mounting holes will go, not just where they may go as recommended by past versions of the standard. This will [eventually] ensure no extra standoff could end up under a motherboard. However, this only applies to newly designed and marketed cases and motherboards. Not all existing motherboards or cases currently on the market or out in the field comply with those latest standards - yet. So, you still should verify you only inserted a standoff where there is a corresponding motherboard mounting hole.

This is why its been recommended to taking everything out of the case and assembling the computer on a large, unfinished bread/cutting board to see if it boots there. Then inspect the case and verify again, only the necessary standoffs have been installed in the correct places before reassembling back inside the case.

it happens like 1/50 times i turn on the pc

The worse case scenario for even the most skilled and qualified technician equipped with the best troubleshooting tools is "intermittent" problems he or she can not duplicate on demand.

A problem that seems to occur out-of-the-blue only once in 50 attempts would be one of the worst of the worst scenarios.

Breadboarding, as suggested, but ignored more than once by multiple advisors eliminates from the equation the case, its switches, its indicator LEDs, its USB and audio ports, and all their associated connections to the motherboard. AND it is a way to double/triple check connections to the motherboard and attached components are correct and secure.

I agree with the guys above, you really should take your computer to a shop.

 

[kapone32]

When you did a fresh install did that include DDU?

 

[matpc]

this was a completely new build along with m2 ( completely clean install)

 

[kapone32]

Yes but you reused everything else in terms of hardware. As the GPU light comes on (unless the MB is faulty). Every since that Physx update switching from AMD to Nvidia can lead to problems. In fact just changing Video cards alone is a good reason to use DDU even if AMD software is basically universal.

this kit did not have any of the drivers/files from previous build

went from sata drive to m2 and anotehr gpu as well

used windows media creation tool , completely nuked the drive before

Did you pay for a brand new Windows key? Did you use your MS account to recover what you wanted? With PC there are always a myriad of reasons that can cause problems. Could be as simple as there may be some AMD registries that may have been installed when you reset or MS downloaded based on your previous profile. By the way it was just a suggestion. I understand that you used new Equipment but you still kept the same MB/CPU combo.

this is what bugs me , it should glitch in the boot light

i know that we cant trust 100% the mobo lights but still
