Hello,
It sounds more like you are having driver issues/incompatibilities with the old card. This is how you fix that:
First, install DDU: https://www.guru3d.com/files-details/display-driver-uni...
Next, install iObit Driver Booster: http://www.rs.iobit.com/en/driver-booster.php?
Then, boot into safe mode (with networking). To do this:
1. Type "msconfig.exe" into the windows search bar without quotes.
2. Right-Click on the application when it pops up and click "run as administrator."
3. Navigate to the boot section of the application, and click "safe mode with networking"
4. Hit apply and reboot.
To finish up:
1. Run DDU in Safe Mode.
2. Disable safe mode in the msconfig.exe application.
3. Reboot.
4. Run Driver Booster and let it re-install the display drivers.
You should be done after one last reboot!
