motherboard causing issues?

[FTRGameplays]

my Mobo is an EX-Asus A320M Gaming, when i first bought it i didn't say in the store which board it was i thought it was an Asus with the chipset B450M. For a couple of months 0 issues now from march till now it gave me multiple issues. Like for example multiple BSOD that are different from each other, restarting and even getting Black Screen and freeze. I didn't mounted it the store did and they failed to put the memory in single channel, they also failed to hear me first when i said that i wanted and asus b450m board and 2x8 gskill 3000mhz and that i would install myself the SO. I also gave them a budget and instead of telling me that it would be over the budget they didn't said a thing. Now i am stuck with this problems. I used memtest to test each slot and each ram in each slot and only one was faulty i even took screenshots so that the store could give me another motherboard since this is faulty but they ignored me So now whenever i touch cables of they even move the pc restarts at least that's what i think if i put another motherboard would this fix the problem also i tested both GPU and CPU with furmark, Prime95 and and did benchmarks on it and gave me 0 problems not even 1 error or shutdown after i put the slot of ram in a non faulty until now, i don't even play games due to it. Store said to me that they will call me to get to warranty and replace motherboard with new one and that has been month since then, i also went to another store payed almost 100€ for it and said it was fine till it got home and problems appeared. So should i just buy a new mobo or try to get a hold of the store?

So please explain better "moving cables" which cables??

All the PSU cables that connect to the motherboard, GPU and even Case Cables as well. 

only today happen this 

It is in my home langue but i he restarted it 4 times without me even touching the computer. There was 1 time that i couldn't even boot the computer while i was pressing the power button i just pick up the case gently and put it down and pressed the power button and it turned it on.

Good information. Thank you.

 

All connectors are in good and tight, my next question.....

 

Is there a standoff behind the motherboard that is Not lined up with the board mounting holes possibly causing a short?

Yes all tight good i dunno if i just like grab like the 24 pink and just wiggle a bit the PC might restart same for the 6pin gpu or Case. 

The PC restarted again this is the 5th time. I will check if the other side of the motherboard.

That sounds like loose connections. Triple check them any ways. Must be pushed all the way in and the lock tab is down. 

 

Also, to note that the male pins on the motherboard side can break loose. So be sure to remove each connector and view the pins are all still soldered to the board, if not, they will likely pull out and be stuck inside the PSU female connector. 

 

If all is good, I'd remove the motherboard and be sure all the stand-offs are in the correct corresponding pattern to the motherboard.

The PC restarted again this is the 5th time. I don't know if this is a problem of PSU or Motherboard but i am more inclined to be the motherboard. This PC i bought in October i had 1 that lasted 4 years (dust and humidity) and i builded myself i had some parts that caused me problems motherboard that was pretty cheap and i died a Bios update of mobo in Windows and GPU bios as well and the only problems were Motherboard and Graphics and that's all. This seems to be pretty similar but this PSU is 10x better than the old one that was XFX 650W Semi-Modular XXX Edition

 

PS: All the standoffs are tight. 

PS2: Teste the PSU in my old computer that has humidity and dust just to see if  the problem happens and guess what it really happens when i touch even just a little bit on the 24pin the turns on the computer and restart's. I just put the chassis front panel Power_Button just to not be bothered to use a screwdriver on the pin and i didn't even need to touch the power button to turn it on. Sorry if i am repeating myself it's just to be clare. The pins on the motherboard are soldered and not even bent. This is my power supply Seasonic M12ll 620W 80+ Bronze Full Modular, i can only put cables on just one side i guess i have either to buy from cablemod but i am not sure if it's just the cables itself or rather the connector of when i put the modular cables of the PSU
