Need advice on desktop random no POST

[Nigelnkj]

Harlo,

Back in 2023 I built my own rig, deeds here, https://pcpartpicker.com/list/wxNVDw

Right now the desktop will randomly not POST on boot, my CPU and DRAM debug LEDs will stay on when it happens, sometimes need to restart a few times, sometimes more than 20 times, its very random. Doesn't matter if EXPO is enabled or not, just tonight I tried to flash the latest bios via M-flash but I couldn't even boot into it after 20+ times, in the end resorted to using the flash bios button at the mobo IO. Even after flash the problem still persists. Tried single stick in all 4 slots, it still seems to be random.

I have tried leaving the desktop as it is for ~1 hour when it happens to see if it POSTs, but as of yesterday it does not. The desktop is unable to wake from sleep or restart since I built it. I initially thought this was due to the RAM, but after changing it out for a new set last year it is still happening.

Abit of history, during the assembling i dropped the cpu on the mobo pins, can see the photo here. back then did some hail-mary re-adjusting of the mobo pins, heres 2 photos i took earlier this year while troubleshooting the mobo, from the top looks fine but from an angle you can see the bent pins




At the time it was built I was actually running 4x8GB of 5200MT/CL38, back then the rig already had problems, BSODs and hangs specifically on Helldivers 2, cannot wake from sleep and cannot restart (only DRAM light will stay on when it happens). Decided to change to the current T-create expert 6000/CL30 RAM when the price droped to 150. I don't remember if the no POST issue was already there before I changed the RAM, but when the desktop does POST with the new RAM there isn't any BSODs/hangs during gaming or such. I believe its either the mobo or CPU, but don't have the means to test it.

Now the mobo prices going to go up liao, im comtemplating if i should take a gamble to change to a B850M board and see if it solves the issue, but would like your opinions on it

nigtraven yst got share the Asrock challenger going at below 160 from amazon. just change to that mobo that he intro before price goes up

 

[soreloser]

yeah probably should change mobo, especially if the bent pins can still be seen at an angle even after adjustment

So u found the pbm by urself. If can maybe can try repair the bent pins which may require careful skill to do it.

Was at SLS yesterday most stores quoted 250 minimum for a Matx, 400 for the b850m equivalent of my current one.
Decided to go for the Amazon ASRock Challenger

Have tried repairing twice, once back when assembling the another time this year, but second time I couldn't do much as I didn't take the Mobo out of the case so couldn't see v clearly. Planning to try a third time when I replace it with the ASRock one. But all this is if the Mobo is the issue and amazon delivers

Hey I have a similar issue and it gets worse where it would not boot up at all.

Prior to that will have black screen where the gfx would shut down.

The culprit was the power supply and I have the same gx series (rma once from fx-750 to gx-750) and 2yrs later same issue.

I suspect it's the power supply is not resigned for atx 3.0 and giving unstable power which resulted in the random not booting .

Changed to a newer power supply which supports atx 3.0 and problem resolved.

Interesting, but ya my PSU isn't atx 3.0. Decided to go for Mobo first cause it was already damaged, but will KIV if it doesn't work

My random BSODs/hangs were with the old RAM I was using tho, the new ram so far haven't have any. Not sure if that is what you mean when you said black screen

Harlo update, I have received the ASRock B850m and swapped out the mobo

Aside from some different locations for the fan pins, mostly managable. However this mobo's PCIE slot is a slot higher than my previous one, now the gpu takes up the first 2 PCIE case slots instead of the 2nd and 3rd one. Had to remove one of the top fans to mount the PSU higher to make space for this. Took a good 15 mins figuring if I actually inserted the GPU in properly or not cause no space see the connection to tell. Will need to get a longer GPU support stick as my current one too short



Now the POST issues gone le from the few restarts/boots I have tested. The PC also can wake from sleep. However there was one instance where my boot and GPU debg LED was on, but it was displaying black screen with crusor (the screen you see before the Mobo logo and windows loading animation). Will see if it happens again.

Thanks all

Sorry I wasn't around for a while.
If I reply to your earlier I would have advice not to buy the Asrock B850M.
I just returned my Asrock B850M Pro-X after some BIOS bug.
Make sure your BIOS is up to date as there's a known Boot up issue with Asrock B850M series.

You can see past BIOS version did mention this:
"3. Resolve a boot failure occurring on certain CPUs."

https://asrock.com/mb/AMD/B850M Challenger/index.asp#BIOS

You test if there's issue I would suggest you return the motherboard.
Get a Gigabyte motherboard the BIOS will be more stable than Asrock.
Not sure why Asrock current generations motherboards are like that.

I do owe the Asrock A620M but that one has been very stable.
BTW for Seasonic PSU you can get the 12hwpr cable than using the adapter.

Yep did a BIOS flashback to 4.43 first before booting, the bios USB port was not easy to identify haha

I had a plan when I built the PC back in 2023 to upgrade the CPU + GPU either this year or next year, this year due to some conditions I don't have the moolah to do the upgrades. Planning to change to a X3D and AMD GPU next year seeing the prices of Nvidia cards, probably won't be using the 12hwpr?

Since i already have the faulty motherboard out I'm planning to do a proper check/adjustment on the pins. With the upgrade I do have spare CPU to build a second PC with SSD from old laptops for a home PC. I'm aware of the X3D disaster with ASRock specifically, so planning to use the X3D on my faulty mobo in the home PC case to test if I can fix it, then transfer over the mobo back to this PC if it works. Tho this plan hedges on if I can fix the mobo pins and it works

For the 7600 specifically seems like the burning issue is due to VSOC set to 1.3 based on Reddit? Checked the BIOS, now its at 1.2

Current Asrock motherboard B850 series in particular is not just the voltage too aggressively.
When I got the Asrock B850M Pro-X, I encounter boot up issues.
XMP/EXPO not stable it failed to post or revert back to JEDEC sometimes.

Just monitor as the set I have, my set is less than a week there's issue.
Take note if you want to reuse SSD, the Windows best to reinstall from scratch.
*Not Windows set.

Good to hear that ur pbm is solved. Troubleshooting a PC always need time n effort and the pbm will be solved.
