Unable to Start SC2 after installing new GPU

Dear Technical Support Team,

having installed a dedicated graphics card MSI Geforce GTX 970, that works great with any game I tried, I am having troubles starting SC2.
Any attempt to start the game results in a flickering screen (Black/Desktop), ending up in showing the desktop and SC2 in the task-bar. The game can’t be started.

Having checked the Gamelogs it’s obvious, that something with DirectX is not working. Having researched (maybe not well enough) I tried several solutions - De- and Reinstalling drivers, BattleNet, SC2, DirectX etc. - nothing of use and still the same result.

Hey Heinzmungu,

In the past I’ve seen this happen a few times. Typically, deleting the StarCraft 2 folder in the documents folder as well as unplugging your monitor and plugging it back in has fixed it.
If the issue continues after that I do recommend putting in a ticket with us and include system files so we can take a look.
You can follow this link to create a ticket: Contact Support - Blizzard Support
Here are instructions for the system files: Obtaining System Files - Blizzard Support
