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?

I should clarify that the PC does power on, but does not pass POST, nor beep at all. There is no signal to the monitor aside from a straight black screen.

Hi,
I have a Presario SR5050NX and want to upgrade the video so it supports Windows 7 Aero properly. I put in a new PCI Express (ATI based) video card and tried all the BIOS settings. I'm getting the same results you describe. System powers on but the screen stays black. I'm not sure what to do.

Any suggestions?

Thanks

Emery

Can you test a Nvidia card?
