I have tried both the FirePro 3D Graphics V4800 (this one was working previously) and the ATI Radeon HD 5450 1GB. But when I put the Radeon HD 5450 in, I get this: Attention: Unsupported Video Configuration Detected
Action is Required
This computer has an add-in graphics card, but the monitor cable is plugged into the integrated video connector. To attach the monitor cable to the add-in graphics card:
- Shut down the computer
- Plug the monitor cable into the add-in graphics card connector. This may require a video adapter or video adapter cable. (provided with system)
- Turn on the computer.
This message should not appear after completing these steps. For more information or help, please refer to the system documentation. System halted! Just as information, I unplugged the drive in SATA-0 and I get a squarish 0 with a dot in the middle instead of one with no dot and more round.
