Problem: Many of my images in PowerPoint files appear as a red X instead of the image showing. I can work a file for a while, close it, re-open it and it shows the Xs. Source of images are multiple but usually: Screenshots, png or jpg from my laptop or our server, from Internet. I have worked the same way for the last few years and never had any issues of that kind until recently. The problem seems to be occurring at irregular intervals. When I restart my laptop the problem is solved for awhile. Can you help.
Here's my laptop info:
