hi, i built a system yesterday using all new parts bar my GPU which i bought from a very respected Ebay seller. Over today and yesterday ive been experiencing crashes, that when occur i get small blue and green squares on my screen then they disappear. Sometimes they are BSOD sometimes it just crashes my PC and i have to manually restart, when i do manually restart i tend to get bright blue lines on my screen as soon as i boot up but they go away and the computer proceeds as normal. The past few BSOD's have given me error codes, one was realted to my bios needing flashed which i have done, the other is video_tdr_failure (nvlddmkm.sys) which is related to the driver of my GPU. Obviously to combat this i have updated my drivers, i even uninstalled them all and reinstalled the correct ones. I contacted the guy and he claims that there was no issue with the GPU when he had it so i asked a few questions about his system. The only difference is that he ran it with a HDMI cable instead of DVI which i am using and he used Windows 7 instead of 10 like me. Could either of these factors be causing this or am i dealing with a faulty gpu. The only reason why i havent assumed its a faulty GPU is because it runs perfectly fine doing anything but gaming, even when i game the temp does not reach above 60 degrees and it doesnt actually crash when im playing its only if i tab out for too long or i close the game completely that it crashes.
 
Solution
What kind of cpu do you have? If it has integrated graphics, try taking the graphics card out and using the integrated cpu graphics. If everything works fine when you do that, then it for sure is a bad graphics card.
It may be an issue with the connector and OS, but the way it crashes seems more like a bad card.
Only way to make sure is test in a Windows 7 system with HDMI, but I'd say 80% chance it's a bad card.

Another thing that may be is that your power supply is not good enough to run the card.
