Hi,
I'm afraid I don't have many ideas, I'm sorry.
A regular application (like PTGui) shouldn't be able to lock up a
computer completely. The application itself might lock up or crash due
to bugs, but the OS should always keep running. If entire computer locks
up, that's indicative of a driver, hardware or OS problem.
On less powerful machines, temporary lockups might occur due to the
computer running out of RAM and the OS starting to swap heavily. And
problems may occur if both RAM and swap space are depleted at the same
time. But that can't be the issue with this amount of RAM.
GPU acceleration also sometimes causes problems, OpenCL has not always
been stable in the GPU drivers. But you've already tried disabling this.
Have you done a memtest? Bad RAM is common, I've experienced it on
multiple machines. With this amount of RAM chances of a bad stick are
higher.
Kind regards,
Joost Nieuwenhuijse
