I have an expensive computer 64 mg memory graphic card, my older computer worked just fine. Computer was checked out by dell nothing wrong with it. Dell says it is an Photoshop issue. I have no idea who to do. I can't find a phone number to call Adobe
Can anyone help me?
Without exact system information and details liek exact version of PS, images used etc. nobody can tell you much. From disk access issues that freeze PS's swap files to mundane graphics driver issues this can be anything. In any case, check your device manager, drivers and the relevant PS preference settings.
What have you done for trouble-shooting so far?
Restoring Preferences after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved might be a good starting point:
