SIGSEV Error

I was working on my old PC with the following props:
1. RAM 32 GB
2. CPU - i5 10gen
3. GPU - 1660
4. 1TB SSD
5. Ubuntu 24.04

I was always getting SIGSEV error, no matter for jetbrains soft, chrome, postman or whatever. I spent about a month to fix the issue, but couldn't. I added/removed/modified SSDs, RAMs - but failed again. I got that nervous so I ordered a powerful gaming PC with the following props:

1. RAM 64 GB 5600Mhz
2. CPU - i9-14900K 24(!!!) cores
3. GPU - 4070 Ti Super 16GB
4. 1TB NVMe
5. Ubuntu 24.04

Now I again have that horrible error and phpstorm crashes. I have no idea what else I can do. Maybe I build a nuclear station inside my PC case I'll not see that errors? 

I don't have that heavy software launched - only Phpstorm, Chrome and postman. 

 

This is the screenfetch output:

Hi,

Your issue is highly a hardware issue or some OS issues because you have seen this issue in other apps except our IDEs.

> 2. CPU - i9-14900K 24(!!!) cores

I noticed that you are using intel 14 series i9-14900K.
It is possible that your issue is caused by this CPU because intel 13&14 series can cause crash issues when using apps and running games.
See related articles here for details:

https://en.wikipedia.org/wiki/Raptor_Lake#Instability_and_degradation_issue

Please try to update your system BIOS to the latest version to see if it helps.

Hi bios is latest version. What else can I do?

Unfortunately, we don't have any good suggestions here.
Because this issue affects Chrome and postman, I think this should be a hardware issue. Maybe some of these apps, including PhpStorm, use some APIs and trigger this hardware issue.

I would recommend you use some ram test tools like https://www.memtest86.com/ to test if you ram have some issue.
If your ram is fine, then you can try a different CPU like intel 12 series in your computer to see if you still have this issue.
If it helps, this could be your CPU issue.
