BlackMagic Intensity Pro's Media Express constantly freezes

I have had this card since november it worked beautifully. But ever since I reinstalled windows 7 last month, media express freezes at random places, says "Not Responding" and when this happens the video recorded is corputed. The freezeing issue is random, sometimes I can record for an hour no problem, other times it freezes after 5 mins. I have the exact same drivers for windows and the bios and everything else works fine. Media Express is the only thing thats having problems.

I have tried:
Updating to the newest drivers (Desktop Video 9.5), even tried old drivers
Changing the power options
Using an HDMI splitter instead of the cards HDMI loopback
Switching the card from a PCIe 4x to a PCIe 16x


perhaps it overheating, so now I max out all the fans on my Antec 1200 and see if that makes a difference, if not, I will try to format my raid 0 and reinstall windows
