PC keeps freezing, is it my Motherboard or Is it just Java in General

[PartyWire]

Hej, my PC keeps freezing i am facing a little problem. I wanted to play Minecraft JE with my brother, upon launching the game, my PC froze. Rebooting gave the same result upon opening minecraft. I thought that maybe i have some kind of software that was interfering with java and causing my pc to freeze. Tried my SSD in my brothers PC, it didn't freeze. Tried his SSD in my PC it froze. Swaped ram sticks, mine froze, his didn't.

Swaped CPUs, same story. Also swaped GPUs. Same story. So i uninstalled every java jre and sdk i had. Reinstalled just the java 8 jre, still the same. So i stressed my pc with other games and programs that i know might be intensive on my CPU and/or GPU. Every program that was written in java pretty much automatically froze my pc, everything written in anything else than java ran just fine. 

 

 

 

What i tried:

Hardware:

GPUs: R9 380x, GTX 950, GTX 560Ti

CPU: FX- 8450, FX- 8300

RAM: GSkill 2x8Gb, Kingston 2x8Gb

SSD: Kingston 960Gb, Kingston 480Gb

Different SATA ports, Over 10 different SATA cables.

 

Software:

DDU for display drivers

Different programming language programs (Python, C#,C++, java, Javascript)

Different benchmarks (Crystal disk, Unigen Heaven, etc.)

 

Cases when it froze:

1. Launching Minecraft Java Edition, but not when launching Bedrock edition.

2. Running Old School RuneScape (~15 minutes of gameplay and froze.)

3. Minecraft server jar just to test it, the 1.17+ versions wouldn't launch because i lacked java 17, the pre 1.17 ran but froze after i agreed to the EULA.

4. A little UI i made with Java, gave me about 30minutes before freezing.

4. Running chrome writing this post, turned of java running with the browser option. No more freezing.

 

I have a theory but i need other people to confirm my theory. My theory is that motherboard is dying, a little controller that handles RAM accessing or something, is getting overwhelmed by the Java code that the controller malfuntions and causes my PC to freeze. But I don't know how accurate thrt theory might be because my vents still spin after freezing, like my pc is idle. AIO still pumps water.

 

I am at that point where i am about to wipe my whole SSD, delete the partitions and install windows. But i really don't wanna do that since there is so much data i need that i cannot fit anywhere.

 

Help is much appreciated.
