Then I've run my linuxcnc configuration I'm using all the time and ou of 10 tries it crashes like 7 times right on splashscreen.
Then I've tried the axis_mm configuration by right click on linuxcnc and choosing one of the axis basic settings.
I could start linuxcnc 20 times without restart.
Then ive tried my config again and got instant restart.
I'm sure my ini or config have a problem.
I'll try to post both of them
So just to get this clear. Your PC only crashes if you use your own config? If so clearly something is happening when the cards and their outputs are initialized during the startup process.
So posting your config would not be bad idea. Also you might want to pipe the terminal output of the startup of linuxcnc into a file and post that. That way we might get an idea what is being started just before the PC crashes.

As Tomy has already suggested there is probably something going on with how you wired the thing up that feeds back to the PC

Personally I would create a new hal file and copy in sections from the current hal file you are having problems with while testing if and when the restart problem comes back.
Proper grounding techniques are indeed very important (as I had to learn the hard way many years ago) and without a clearly structured approach how you want to go forward you could be poking around in the dark for a very long time.
So I strongly suggest to create an new hal file and reassemble it step by step with frequent testing. Then once the rebooting happens again you can take a step back and analyze what is happening.
