I have a new HP xw4600 workstation. The configuration is 3.0ghz, 6gb ram, 250gb hdd, nvidia fx1800 (slot2), Avid HIB(slot3), and HP 1394 card(slot5) running Vista 64 Business.
The issue is that the system will not boot with the R380 card installed. I have gotten 2 replacement R380 cards, replacement PSU, replacement motherboard all to no avail. I have removed all of the RAM except one 1gb dimm (even tried new crucial dimm), and all other cards except graphics and r380 as well as tried the R380 in each of the pcie slots.
When I power up the system the first time after turning on the power strip, the system boots just fine. After I shut it down and cold boot it again and every time after that, the system will power on for 1-2 seconds then power off, on for 1-2 seconds then power off... then continue this cycle anywhere between 6-20 times before it will actually POST and boot.
I have tried the latest available BIOS as well as having our HP business support rep send me every release of BIOS he had access to... all with the same results.
HP, Avid, and Atto have no good suggestions, and I am out of ideas. Anyone have any experience with this condition that could point me to something to try?
