Really tired of these constant random BSOD's ntoskrnl.exe+75bc0

Ever since I bought this new computer months ago it's already been giving me problems with BSOD's, and the tech company that sold it to me is literally useless to help me with this problem. First of all, I bought it with 2 sticks of 4GB RAM totaling 8GB RAM, but apparently the RAM sticks were corrupt or something, tried exchanging them various times, and the corrupt RAM gave me BSOD's when there were 2 sticks in, but it works fine with only 1 stick of 4GB RAM. The 2 sticks are apparently conflicting with eachother and the tech company decided to give me 1 stick of 8GB which I'll be recieving/trading in for the 2 4GB's next week.

Moving on, sometimes even with 1 RAM stick I still get BSOD issues. I have bluescreenview and eventually it all leads up to something called "ntoskrnl.exe+75bc0". I feel like they built my computer wrong or something. But I also feel like it's an NVIDIA Graphics card issue. Thing is I don't know what to do about it as I'm not knowledgeable with computers.
Back when I tried using this computer with 2 sticks of 4GB RAM it worked except when I tried to run games like League of Legends, it simply would just outright BSOD when I ran a game.

I also BSOD'd 2 times while typing this thread, after receiving today my computer back from the tech company who are basically like "idk" towards the whole situation.

If anyone knows what the problem is and what I could do to fix this, help would be very much appreciated and I would be very graetful, thank you.

Hello. Thank you very much for your reply. I have done exactly as you said regarding uninstalling everything Nvidia related and reinstalling it to the driver version you pointed out.

No blue screen yet, I'll try to "force" it by playing games and watching videos (anime). I have not done the memtest yet though, as it's not night yet for me and I'll do it overnight. But I have a question.

You told me to update the Network driver for Intel. I went on the page, did the auto-find update thing, and it says the "Wired Networking" driver is up to date, if that is which one you meant. The only thing updateable on the Intel site for me is a "Audio Driver for Intel Desktop Board" update.

"Wireless Networking (WiFi)" says unsupported but I'm sure that's not the one you meant. "Graphics driver" says unsupported, and "Intel Chipset Software Installation Utility (Chipset INF)" says valid/up to date.
So I think my intel network driver is fine?

But anyways, does this mean I can't update my nvidia graphics driver further than 314.22? Also, am I allowed to download the "GeForce Experience" program I had that automatically kept the drivers up to date, optimized games, etc? I had "download beta drivers" checked, too, on it. (Just wanted the best for my computer I guess).

Thanks again.

OKAY WELL. Ran memtest86+ and even at phase 3 it got.... 8 errors. Wonderful. I'm really sick of these corrupted RAM's that this company is giving me. Just called them and they said they'll deliver a "new" one tomorrow, but I've already exchanged different RAM sticks several times with them and none of them ever worked.

Alright well... the RAM issue is one thing. Is there any other driver issues or computer issues aside that that I should be worried about judging from my minidump? I wish there was like a program that can just fix every single thing that's wrong with my computer at this point. I can just feel that something isn't right.

I uploaded a new minidump I guess, to show the BSOD's I've had since performing the tasks I was instructed to.

Thank you, again.
