Hi All
i wonder if anyone can help with a problem i cant seem so sort out
I have rebuilt my old system into a new case. I was running
asus blitz extreme
qx9770
2x Asus 3870x2 cards in crossfire
4gb corsair dominator 1600mhz ram (did have 8gb but runs better with 4)
termaltake toughpower 1475 watt psu
build went well installed fresh copy of win 7 64bit no probs
wanted to upgarde graphics cards so bought 2 sapphire HD4870 x2 cards cheap off ebay (money but tight atm due to tarting up my house).
i put both 4870x2,s in connected correct power connectors and started up. instantly 1 short beep followed by 2 longer beeps. powered down took bottom card out booted to windows fine. I then tried putting a asus U3S6 sata3 adapter card in second pci-e slot. Same thing 1 short 2 long beeps
I have tried another blitz extreme MB and swapped ram about every combination of pci-e cards boots ok including my original 3870's
as soon as i put 1 of the 4870x2 in either slot and add another card the other slot gives beeps
ps. the 6 and 8 pin power connectors are plugged in
and the pc boots into windows ( i hear start sound ) just got no screen
i looked long and hard for an answer sorry if this already been answered
thanks for any help i get
Cheers Nick
