A customer was successfully using Skype, but the latest version locks up as soon as we try to do anything. In fact, the entire computer locks up and we have to cycle power to the machine to regain control.
I have used Revo Uninstaller to uninstall Skype and downloaded and installed a new copy, updated Windows 7, updated the AMD Radeon driver, turned everything unnecessary off in the system configuration utility, disconnected the webcam, uninstalled the webcam software, run Superantispyware, and created a new user profile. Nothing has helped except that in the new user profile the computer itself does not crash, but the Skype process can't be killed in Task Manager.
We are having trouble finding an older version of Skype to install.
What do I have to do to make Skype behave?
