Pc wont post

I finished assembling my pc August 21st 2020 up until last week it ran flawlessly without issue. Last week my computer randomly shut off during a fairly low load(I was only watching YouTube on a 2nd monitor). Upon rebooting it my pc wouldn't post and my ez debug light was lit up indicating the dram was the issue. I went to bed and tried booting the next day without changing anything in my pc and I was now getting dram and vga lights. I start troubleshooting and remove 1 stick of ram. Still dram and vga light. Tried both sticks in every possible slot combination still getting both lights and intermittently the boot light. Up to this point I have cleared the cmos, completely rebuilt the pc with every component checking and reseating every cable. Pulled the mobo out and flashed the bios with only the power connected to the mobo. After the rebuild I got 3 debug lights, dram, vga, and boot. I pulled one stick of ram and then I just got a dram light. Restarted again and got dram and vga light. Another restart and dram, vga and boot lights. I think my mobo is defective or something but at this point I'm lost.

That was my initial thought. I've just been hesitant about buying new components to test because by the time I land on a solution I'll have basically built a new pc. I have a ticket in with msi so I'm gonna see what they have to say and rma it if they can't help. Msi boards have a 3 year warranty so it should still have about a year left. Thanks for the response.
