PSD save crashes Windows and reboots PC.

PC crashes when saving PSD. Crash report only shows the PC rebooted. I can save PNGs without issue. I am current on Windows and graphics drivers. I tried different scratch disk, disabling use of graphics processor. This is a fresh install of PS. I have been using AI without any issues. I tried older version of PS and same issue. When I hit save it is an instant reboot without any delay. I dont have any issues with any other programs saving files. I have shut down any non essential processes but it does not help. Not sure what else to try.
