I think my GPU dead bvut there are othe wierd problems. It started with no image displayed when turned on but if i pressed the the reset button it started fine. then i took the gpu out the incase it was a bad connection but when i put it back fans would stop and start and no image diplayed. then i chanded PCIe. then it got wierd. i got m=no image so i turned off and on and went into the bios. Tryed to exit but just exited and came back into the bios. turned off and on, booted up but windows 8.1 zoomed way in and the restarted itself after 5 secs. the came up again zoomed in but after 15sec(roughly) zoomed out to m=normal but underestimated screen size by 10%. put it back in top PCIe no image back to the second no image. tryed multiple times no image. Thanks for any help you can offer!

I had this problem with a unsupported pcie slot. version 1.0

But I don´t understand why this mainboard won´t work with your graphicscard.

It´s your mainboard(try a different model) or graphicscard(defective?!).

can you check if your monitor has the feature called "over scan" activated? If so, disable it in the monitor menu.
