Hello, I Purchased a evga gtx 660 a few weeks ago for a new build i was putting together. i was trying out a game i had when all of a sudden the monitor just blanked out, yet all lights were on. I shutoff my computer and rebooted it. It posted fine and went through the bios OK, showed the starting windows logo for a brief second then i couldn't see anything again. i tried two different monitors, every kind of connection the graphics card has. I then shut it off and checked all the connections, unplugged and re-plugged in the memory. i don't have any spare comp components to try to see if it is one of parts of the build.one other bit of info, my water block has a led light on and it will no longer light up. lastly, after checking all of the connections and trying to turn on the comp again it will no longer POST. I have ran out of idea's, can anyone help?
