Resolved the black screen issue i now run it as
psexec \PCNAME -s -i C:\Users\User1\Documents\pptautorun.bat
pause
no idea why this has worked but it does, but now it comes up with a pop up saying that Powerpoint cannot read the file, but when i tested the .BAT file that i have on the local machine it opens up the .ppsm with no issues.
and now im stuck again
