Question motherboard causing issues?

[UltimatMaxxx]

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?

Well - from what I can see, Memtest have reported zero memory errors.

Did you install windows from scratch? Have you ensured the computer have no virus/malware that causing this errors?

It's not virus i tested the PSU in another computer and just gently just waved the PSU 24pin connector and the computer just restarted itself and if i just grabbed i couldn't even start the computer not even if i pressed the power button or used a screwdriver at the front panel Power_Sw. But i am not sure if it's the cable itself or the modular connection to the PSU.

just gently just waved the PSU 24pin connector

At what end? On the PSU or the motherboard connector ?

Motherboard but it's the 24 PIN cable

You're having problems with PSU itself i think, not the MOBO or RAMs. I had a bad psu, when i shaked a little bit, pc always restarted. When i touched the PSU, pc restarted again.
Try to find another PSU to test on your system. (sufficient one of course)

I had bad PSU cable problems back then, with another PSU. One of the molex cables was defective and i had a lot of issues, hdd didn't work properly, VGA not found errors, blue screens etc, even DVD-ROM errors just because of a faulty PSU Molex cable. I told this so it might give you an idea, who knows.

I dont have another psu the old one died the only way is to take it to the store also it's the PSU Molex cable, there were times that i got blackscreen and frooze my computer but that's all i think.
