7950 red screen on DVI

post #1 of 2
Thread Starter 
See second post for the short version.
I have two Sapphire 7950s that have been working fine for three weeks. I installed waterblocks on them and now one card will no longer be recognized by windows. I have installed waterblocks before so I am pretty confident I haven't done something odd or wrong. I didn't spill any water when installing them. The only dumb thing I did was cut the computer on at first without the crossfire bridge.
I uninstalled the drivers with ATIs new driver utility and reinstalled drivers.
I took both cards out and tried them one at a time. One works one does not.
The working card was reading 30c and they were both getting water flow (in series) so I don't think I cooked it.
I took the block off of the bad card and the thermal paste and grey sticky heat transfer pads seemed looked good.
Before I freak out have I missed something simple?

I reinstalled the air cooler. The card kind of works now.
I run three monitors. One one via HDMI, one DVI, and one DisplayPort with an adapter to DVI.
The HDMI and the DisplayPort look fine. The DVI monitor looks messed up. It looks very red and has green snow. Is the card dead?

Edit:
If use two DisplayPort connections and and HDMI no red tinted screen or green snow.
