FYI : I'm not talking about cgminer dead, cards literally went dead
1.5 week ago I bought 4 sapphire 7950 Dual-x . They are installed on two different mainboards (asus z77a and amd m5a97). Two of them are powered with 750 watts cooler master bronze and other two are powered with 1050 watts cooler master silent pro gold (I was planning to add more cards).
First, one card which is installed at second pci-e slot (m5a97) went dead, before going dead, system restarted itself several times (I thought it was about electricity in my area) After that card went dead, I couldn't power the system without taking card out. Than, card is replaced by manufacturer. After 2-3 days, card which is installed at first pci-e slot went dead. This time I was able to power the system, but there were no display and fans were spinning at %100. I used 1100/1250 clocks. Temperatures never exceeded 80 celcius. (They were between 77-79 for first card and under 70 for second card)
Same thing happened to one of the cards installed on z77a - no display %100 fan.
Now I'm using two brand new sapphire 7950 on msi mpower board, I was afraid to overclock so I just oc'ed engine to 1000. Cards worked perfectly for 3 days and now again system started restarting itself and I'm afraid it looks like it will happen again if I continue mining.

I'm using win7 ultimate and 13.9 drivers - cgminer 3.7.2. I got other 7950 cards (asus) and they've been working perfectly for months.
If someone can help me to solve this problem, I will pay some bounty and I will be generous about it believe me. Thanks
