Crossfire problem with my new SSD?!?!

Hi, thanks for taking the time to read this. Anyways, on with the issue. So I have a decent setup that has been getting me by. It is as follows:

Asus M5A97 motherboard
AMD FX 4100 3.6ghz quadcore cpu
16gb (4 x 4gb) corsair vengeance ddr 3 ram
2 XFX Radeon 6770 1gb gddr5 850mhz gpu's
750W OCZ psu with 12v rail
standard dvd rw drive
120gb OCZ Agility 3 ssd

Now before I had the OCZ ssd I had a WD 500gb Caviar Blue hdd. It worked fine, but the other day it started to notify me of bad sectors. So I purchased the ssd off of newegg and when the ssd got here i installed it. I removed the 500gb hdd and used just the ssd. I am waiting for my 3tb external to get here for all of my media. However the problem i am having is whenever i install the drivers for my video cards I get a blue screen of death which is so magnified I can't find an error code on it. It ONLY happens when I have both cards installed. If I remove the second card, everything runs fine. I am a little confused on the topic and I hope someone can help me out. Thank you again for reading and any information would be greatly appreciated.

P.S. I have moderate computer knowledge and access to Google so please be as technical as you need to. Thanks! ^_^
