Could not update smart object files because of a disk error.

Hi, 

swo i've been using photoshop for years and  years now (around 20 years)  and if i find an error i can usually work around it - but recently i have been getting the problem Could not update smart object files because of a disk error.  This only happens when i'm using one of my actions to update smart objects on one of my actions.  

The error can occur at any point as the action is running, some times it works fine, some times not at all.  I dont know if its a problem with graphic card or not AMD Radeon 7900 GRE but its a pretty hefty graphics cart that i only purchased a few months back.  When the error happens the screen goes black, Radeon crashes then i get the error in photoshop.  

i have updated all my scratch disk to all of my HDDs, Radeon Drivers are up to date 

one final thing - the action opens 9 files (which after updating then saves as a copy in jpg format and closed) , one at a time and uses a template file for the smart object info.  the template file is pretty small 1500 x 300 px i think  

Thanks 

Simon
