I recently upgraded my GPU at a local IT store, and they showed me that everything was working fine before I left. However, when I got home, my computer wouldn't display anything on the monitor. Here's what I've already tried:
- Using brand new cables
- Trying different monitors
- Setting everything up in a different room
- Switching ports on my computer to ensure I'm using the GPU outputs
- Plugging the computer into my TV via HDMI
I took the PC back to the repair shop, and they reinstalled Windows, believing my system might have been corrupted. They demonstrated it working there, but when I got home, the same display issue occurred again. I'm really at a loss here—any advice would be greatly appreciated!

Make sure you’re cycling through the correct input on your monitor. What kind of GPU did you upgrade to? Also, does the card seem to power on when you turn the PC on? It’s a bit odd that you only face this problem at home. Maybe it’s worth reseating the GPU in another PCI-E port—could get things working again!
It sounds like you’ve done a lot to troubleshoot! Just to cover all bases: are you sure you’re connecting the HDMI cable to the GPU? Some cases have HDMI ports that don’t connect to the GPU at all. Also, check if the monitor is powered on and set to the correct input. If nothing works, maybe take it back to the shop with your monitor; they should be able to help you out more effectively than trying to fix it on your own.
If all else fails, consider taking it back to the shop. Ask them to create a system restore point for you after they get it working. Also, have them check the BIOS settings to ensure your GPU is set as the primary graphics source. I've had issues with that leading to similar problems.
