After updating Skype to the latest available version your computer displays a Blue Screen of Death (BSOD), followed by an error, “Skype can’t connect”.
Disable Automatic Updating
Prevent your computer from automatically updating Skype to latest available release. Find the Automatic Updates > Turn off automatic updates under Advanced tab in the Options dialog. Open that dialog from the Tools in the main menu.
Install Generic Microsoft Webcam Drivers
You may encounter BSOD after updating Skype if you’ve HP Drivers installed. Just remove them using Device Manager (Ctrl + X); or Programs & Features (Control Panel), perform a hard reboot and then install generic Microsoft webcam drivers.
Disable Hardware Acceleration
Go to Microsoft DirectX Diagnostic Tool using DxDiag command. If the Hardware Acceleration feature is enabled, turn it off using the slider in Display tab.
Disable Skype Startup Entry
Using Microsoft System Configuration utility > Startup tab, disable the Skype startup entry.
Repair Broken Registry
Another smart way to fix Skype errors is to fix broken registry entries through the RegInOut System Utilities. You can download it here: Fix Skype BSOD.
Check if any unsigned drivers were installed. An unsigned video driver causes BSOD after updating Skype. Use Driver Verifier Manager using “verifier” command and then automatically select unsigned drivers by creating standard settings, as instructed in the new wizard.
Restore Default Language
Perhaps your language files are corrupted. Set the default language English (United States) from Tools menu > Change language sub menu.
Disable Using Default Ports
As default Skype is configured to use default ports – Port 80 and Port 443, for additional incoming connections. Uncheck that checkbox under Connection category under Advanced tab in the Skype Options dialog box.
Sign in with a Different Profile
There may be issues with the Skype account. Sign out from the Skype menu in the main menu, and then sign in using a different user account.
