I've got an older GeForce N6600LE-256DZ video card that I want to repurpose for an XBMC box.
I installed it into the PCI-E slot of a working Windows XP SP3 box with an ASUS P5GZ-MX motherboard, updated to the latest BIOS version (901).
When I initially stuck the card in and booted, it crashed with a STOP ox7E error, but then let me boot into Safe Mode, where I installed the latest drivers for the card from NVIDIA. I restarted the machine, but once again the machine crashed with the same STOP error.
If I pull the card, it boots through normally, but as soon as I add it back in, it crashes during the Windows XP splash screen.
In Safe Mode I can see the card in the Device Manager and it says it is functioning normally (which it is as the VGA monitor is plugged into it).
