Whole machine lockups, shutdowns, and restarts cannot be caused by applications.
They can only be caused by bugs in the OS, bugs in low level drivers, or defects in hardware.
Lightroom and Bridge run fine. It is only Photoshop that is not functioning.
So, it cannot be an OS or hardware issue..
Photoshop was running fine on the same hard drive till it got infected with spyware and I had to reformat the hard drive and do a clean reinstall of everything.
I am not sure what is causing this problem
