motherboard What a weird probelm. Motherboard half dead. Updates coming soon

[SavageNeo]

So. This is pretty odd. But this pc has had problems before. Like not booting, suddenly shutting down on idle etc

 

Specs:

Asus b550-A

Ryzen 7 3700x

2x 16gb tident z rgb @3600mhz

Strix 5700XT

TT toughpower Grand rgb Gold 750w psu

 

 

So lets go back a couple days. I got my motherboard extension cable on mail. But it was already night, so I decided to get it the very next day. I unplugged the psu from the wall and took out the motherboard power cable, so the next day i could just plug the extension cable in. The extension cable in question is the Lian Li stimer V2 RGB 24pin.

 

Fast forward to next day. I plugged the extension cable in, the pc was not booting. Sometimes this exact problem happens, when i have unplugged the psu. Mayby mothebroard capacitors drained and caused problems?? Wierd. but this happens 25% of the times after the psu have been unplugged for sometime., So usually the problem goes away after couple reboot attempts. But not this time!!

 

The dram led was on, but the beeper was beeping video card issue. Hmm Wierd i thought. So pulled gpu out, still the same led and beeping. Well, pulled the ram out, still the same!! wtf i thought??? Tested the ram, and gpu on my testing rig and worked fine. Also tested a different psu, ram and gpu that I knew were working. Still the same dram led and beeping. 

 

I was pretty tired, So I took the cmos battery out for the next night and unplugged the pc. 

 

Well fast forward to second day of torubleshooting, after the cmos reset still not booting. Wierd i thought. Well I ordered a stock cpu cooler, since I was running an AIO. Im still waiting for the cooler.

 

Well decieded to use my test bench to play games, and left my pc unplugged to wait for the stock cooler, So i could rebuild it out of the case.

 

Well not it gets even more interesting. Fast forward to third day, just casually plugged the pc in and it booted!! Well with onyl 1 stick of ram. Dual channel would nto work, So i had to put the ram on slots b1,b2. Well booted fine. Tried 5 different bios version, still no dual channel. hmmm. XMP worked So I just thought ok then, not a big problem.

 

But more probmels arise!! The rgb of anything else than the gpu and ram was not working. Douple checked all the wirings, they were all good. Pretty odd. Well after I updated windows, the "cpu fan error" warning message comes. Very wierd i thought sicne the AIO pump and the fans are connected, never had this problem before. Also there is a slight smell of mayby burnt electronics? cant really tell. Anyway ordered a new motherboard, will use the pc until it comes

 

Also motheboard reports my cpu temp as 9C. and cannot see any of my fans so they run at 100% and very loud all the time. At this point i was convinced that the motherboard somehow died? but how tho?

After I mroe reboot the case RGB kinda works, creeps me out. Just flashes different colors or 1ms. Pc haunted?

 

Mayby a short somewhere since all of ths acting up started about a year ago. It started as soemtimes i have to boot my pc twice in order it to work. Then there was those random shutdonw. Just straight shutdowns. Well those happened alwasy at idle, and mayby 2-3 times a week. Did not bother to troubleshoot. Then happened the ram lights. 25% of the time my pc would not boot, until, well many tries, then a lot of memory management blue screens. And now all of this bs. wtf is going on?

 

Most likely will receive the cooler tomorrow or the day after tomorrow. Will keep you updated, if the pc fully works outside of the case. Anyway the motherbaord will take 5-7 days to come sadly. Hope that my pc does not explode while I wait for that.

 

So what do you guys think that might have happened to my motherboard? All o these problems do NOt happen, when I leave the power cablew plugged for the night. But I have ti move the pc 1-2 times per week, and everytime after the psu is unplugged problems start to arise. Mayby @--SID-- has knowledge of this, mayby not, worth the shot.

Garbage board, rma if possible

 

If you cant rma take out the mobo with absolutely nothing connected, take off the socket retention/cover to reveal the golden pads beneath the black plastic, take out cmos battery and clear for 2 minutes, press power button for 2 minutes. Why? Dunk the thing in water, like submerge completely in a bucket of water and also rinse with some running water, dunk for an hour or 2, take it out, and wait 2-4 days for it to fully dry depending on your climate, tropical countries like mine only take ~36 hours

 

The board is fully discharged so no damage will occur, this completely deep cleans the board, basically no filth will remain and completely eliminates filth as being a problem.

 

 

Confirmed working method since i revived a board with this (g31m vs2 but killed cause crossflashed to p5k pro =p) and fixed a random shutdown issue that isnt powerbutton shorting (insta shutdown no shutting down screen in windows) on my z77m d3h which is actually currently p95 large ffts stress test to ensure no more random shutdown shenanigans and this is after cleaning with 99% IPA aka my last ditch method, 99% IPA likely wont clean your board enough so thats why i suggest dunking in water

its the asus strix b550-A. Not a bad board. mayby you confused it for the budget b550 board.

 

Cant rma over 1 year old at this point

 

the water trick mightwork. Will only  test it after the new motherblard comes, so if ti fails, I still can play games

Heres living proof if you dont belive the last ditch water dont work, and yes i did just take the photo since this things still running p95 large ffts to make sure its random shutting off is fixed

 

I call all my dead boards garbage because theyre failiures for maximum emotional damage  though that asus is pretty mid considering its price, weak ram topology wont get you much over 4533 when a lowend b550mh can do 5000 but no real problems other than price and weak ram topology
