I have two GTX 295's in my system (water cooled). I needed to rearrange my loop and took them out for a bit. Once done I replaced them and... nothing.
I reseated them and again, no display on either of them. The green lights are on so power isn't the problem. I could see that the PC was booting as the keyboard displayed and I was able to use the keys to shut it down.
I reconfigured the cards but still no results. I put them in a different machine and still dead. I used the card from that other machine in my system and it worked fine so it's not the system or the monitor.
As far as I am aware the have not been dropped and I'm pretty sure no water got on them as I was particularly careful about that.
Any ideas as to why these 2 cards would go at the same time? They have water blocks on them and I'm planning on disassembling for a good cleaning but can't think this would be the problem.
Will post pics when I get home.
Many thanks in advance!
