270x won't connect to motherboard, but chip gest warm...
I have a 270x sapphire Vapor-X OC and it worked fantastically, with nice temperature and stable fps.
But one day, the card started doing glitches, like when there is a video memory problem. Lots of vertical lines and weird colors.
Then, motherboard stopped detecting the gpu. When the pc is on, chip starts to warm besides the failure. The led of the bios switch and the fans works just fine.
I already tried changing the BIOS with the card's switch, no reults. I couldn't find any physycal damage on the board and it's components. I couldn't detect any short on the circuit. I put the card on other computers. Nothing. I already tried a light reflow on the chip with a heat gun, with no diferent results.
It's seems like somehow conection on the pcie is not working properly, but couldn't figure out if it's an electrical problem or a logical.
