XFX is a very good manufacturer. I have always gotten very good advice from their Tech Support. However, I believe they may not have asked the correct questions. What is the wattage of your power supply unit (PSU)? I believe the 5770 requires at least 450W. If your PSU is less, this may be your problem.

This wouldn't be the first time that a late model ATI card fails to function in a HP. The bios, motherbaord and card all have to work together. You might want to try an older NVIDIA video card that matches up with the wattage and 12+ volt amperage of your PC's PSU.
