Computer rebooting when trying to play wad

[tjshokk46]

I'm using version 1.8.6 cuz we had some issues with the new version here.

The this is, when I try to load a wad I've made with the new version of Doom Builder, one of two things happens.

If I'm using directx, the computer will usually reboot.
If I'm using opengl, It says it found
(GL data found)
GL vert 2.0

Segmentation fault.

I can't help you, but my pc also reboot when i use the new version of Gzdoom ( the SVN version).
I hope somebody knows what the hell is happen on the two situations. )=
