Random BSODs, unrecoverable error occured

Hello, everyone! My first post here. I seem to be having a very random problem, where my computer seems to be BSODing. It happened for the first time yesterday, and now it seems to be happening very frequently. It will tell me an unrecoverable error has occurred, and from what I know, it seems to be pointing to the hardware, but I have no idea what to do. I haven't overclocked, and don't know how to replicate the issue, but I've attached the dumps.

Any help would be greatly appreciated!

I tried everything up to the vanillla reinstall of windows, and now the problem has escalated severely. I cannot even make it past the BIOS message; it just hangs. I've tried clearing my CMOS, and it will let me into the BIOS once, but sometimes, it will even freeze within the BIOS itself. Another problem I had while trying to boot one time was a different bluescreen that said MACHINE CHECK EXCEPTION.

I actually tried this yesterday; I unplugged EVERYTHING, including the ram except for the 1 closest to the CPU, and it still wouldn't boot. I swapped the 1 ram stick with another, and still, nothing. Not being able to access the BIOS was quite gradual. At first, I got BSODs more frequently, then I wasn't able to boot into the OS, and now I can't access the BIOS menu either.

I also got a different BSOD when I tried to do a Windows startup repair after I failed to boot. It read something like Machine Check Exception or something, and I'm unable to get the minidump, as I can't even get into safe mode or anything.

I only have a laptop that wouldn't be able to test the DDR 3 desktop RAM

Before I wasn't able to boot, however, I would be able to run Prime95 for a good 4-5 hours. The BSODS were entirely random.

That's the problem; even if I was to get memtest onto the USB, I can no longer make it past the BIOS splashscreen, so I can't access the boot menu. I put together the computer a little over a year ago, so I should have warranty left on most of the parts.
