I did more troubleshooting on the Skype issue, and found it is definitely a video issue. Event viewer shows Event ID 4101: Display driver iqfx stopped responding and has successfully recovered. This happened after about 10 minutes on skype with anoter staff at the other office. I noticed when the meeting is showing full screen performance is awful. The mouse stutters slowly across the screen, and video seems inconsistent. This happened on both ends. We compared systems and both have i5’s of the same generation, and Intel HD 4600 video. The one site system has 8GB of RAM, and another has 4 GB. It looks like neither system is capable of handling skype maximzed without a serious performance issue, or crash. While skype did freeze I was able to hear other IT support, but not see him. I stopped video, and then started it again. please advise me what to do. Tomorrow we have an executive level conference between these 2 sites.
