Hoping the forum can help where Diamond MM customer support has failed...
I am installing a Diamond ATI 650HD PCIe in my HP e9220f (AMD Phenom II x4 w/ Asus motherboard, 8G mem and ATI 4350 graphic card). After installing and booting, I see the bios splash screen and then my PC freezes. I never get as far as the Windows 7 splash screen and I can not actually enter the bios setup. My monitor is either black or has the top 25% of the screen with a scrambled (similar to horizontal sync issue) image. This is the 2nd card that I am trying and both exhibit the same behavior. I have tried every x1 slot that I have available as well as removing the ATI graphics card (for possible conflict). Same behavior.
Diamond custome rsupport suggested that there may be an IRQ conflict and that I should change out the PCIe unit for a USB based one. Nice.
