My PC randomly Locks up at the windows " WELCOME" screen.
It does it every once in a while. I cant do anything but reset the PC and it works..
Happens like once every other day. But it works fine any other time.
Usually started when i got my SLi up and running.
Both cards work fine on their own.
What might be the problem?

Lockups are no fun... It could be a faulty power supply issue or faulty connectors. There might also be some overheating elsewhere on the computer. Have you tried booting the computer with one card for both of the PCIe slots? Maybe one slot is faulty, particularly the bottom slot.
Ive had this problem for about a month already. But i have not had time due to work. But I've tried switching them Master to slave card and so forth. They seem just fine device manager shows them working fine. The way it locks up is just the screen just freezes but mouse i cant still move around then it just freezes completely.
Their both BFG cards so i cant contact BFG anymore...
I just went sli with the same psu.
So I know it only has 1 6 pin 1 8 pin.
How are you getting your four 6 pin connections ?
Adapters or splitters.
two molex to 1 6 pin ?
If thats the way I would put 1 6 pin in 1 card with 2molex to 1 6pin
The other card do the same use 6+2 connector with 2molex to 1 6 pin
I used Y splitters on the original two pcie connectors I have.
I think this balances things out?
Tried smae thing happened...
locked up... no matter what. I tried the cards each one alone in the bottom slot one of them seems to be running fine while the other one seems to lock up when its in the bottom slot.
