𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: My graphics card has stopped working.
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: We'll reinstall the driver.
𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: That didn't work.
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: Hang on, how are you getting a desktop?
𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: The one screen works but not the other.
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: So the card is working?
𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: I kicked the cable, and now the one screen doesn't work.
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: So reinstalling the driver was pointless, you may have damaged the port.
𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: I'll buy another card from Amazon.
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: Umm? OK.

𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: I fitted the new card, and that doesn't work either!
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: What?
𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: Only one screen works!
𝗦𝘂𝗽𝗽𝗼𝗿𝘁: I'm coming to you tomorrow, I'll need to physically see it.

𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿: It's working now.

I bet he'd pulled the cable out of the monitor, or he hadn't pushed the cable in enough. 😠🤦🙈
