I made a budget build a couple of months ago that included a Galaxy GTX 560 (non Ti) and I bought an arctic accelero twin turbo ii cooler for it for overclocking and noise purposes. I overclocked it to 980mhz (stock is 810mhz) and it ran completely stable and cool no matter what i threw at it, including furmark and max settings on Planetside 2. This morning i went to turn my PC on and my HDTV shows NO SIGNAL and i hear the fans on the card kick in and then stop over and over. I tried unplugging the card, cleaning it, trying different PCI power connectors, etc. but it still sounds like the card is trying to power up but shortly stops.
Could this be a PSU or Motherboard issue? I highly doubt it's the card and how it was overclocked because I pushed it to the limit at 1ghz with furmark and it still didn't crash or show artifacts but i went down to 980 just in case. Max temp was 65 C.
