I have recently purchased the Diamond ATI Radeon HD5770 PCIe graphics card. Upon installation, my Compaq SR505NX will not boot. It had worked and still works fine with my previous graphics card, the Sapphire ATI Radeon HD4830. I have done some research as to the problem I am experiencing, and it seems to be a common issue. All indications point to an incompatibility between the graphics card chipset and the BIOS. I have eliminated other possible causes, such as the power supply. I am currently running a 650W ATX power supply which should be more than sufficient. I have the latest BIOS upgrade that is offered on the HP support website. Some others have mentioned beta versions of BIOS offered by their manufacturers solving the issue. Is there another BIOS update available to solve this issue? Is there perhaps another solution that I am overlooking?
