My pair of 570 Twin Frozrs are back being a nuisance again. (Hate these cards)

Basically, awhile back I was getting strange issues cropping up where I was seeing some artifacting in 3d Mark 11 and the flags at the end during the combined test would be flickering.

I swapped out the SLI bridge and the problem went away.

Past few days i've had a few TDR errors where the screen goes black and comes back on, specifically triggered when loading up FIFA 12.

I ran 3D Mark 11 again and got a hard lock / freeze with it possibly trying to TDR again.

Running the combined test on it's own, the flickering flags were back.

So I shut everything down and swapped back to the previous SLI bridge that I figured to be faulty, reboot and ran the combined test again. This time it was fine. Too early to tell if it has sorted the TDR issue though.

Really at a loss to what is going on with my system.

It seems that by selecting SLI 64x CSAA in the nvidia control panel for FIFA, triggers a problem where even reboots or not playing that game doesn't fix it but a physical removal and re-apply of the SLI bridge fixes it.

How could a software glitch act this way? Never seen anything like it.

My system is 8 hrs Prime stable, 50 passes in Linx also so i'm looking at the GPU/s being the culprit.
