|Install card, computer boots but no signal to monitor.|
I have a Sapphire PURE PC-A9RD480 Crossfire 200 motherboard (99% sure).
AMD Athlon X2 4200+ CPU
2GB Corsair RAM PC3200
Win XP SP3
The card works, i've tested it in three other computers.
I'm pretty sure I have sufficient power (500W) as one of the computers tested only had cheapo 400W.
I have updated the BIOS for the motherboard to as recent as I can find.
Tried different cables/connectors, plugged into VGA/DVI, tried removing RAM, etc.
The only thing I can think is that my mobo is too old for the PCI-E 2.1 - i'm waiting to hear from Sapphire about this.
