Yesterday i got my hands on a new rx6700 xt TUF, i came home and mounted my new psu first and then plugged in the new card. When installing amd software for drivers screen went black during the process. everything seems to run as normal in the backround so after waiting a while i pressed start and tabbed my way down to restart. pc restarts and bios logo appears then windows logo and when the windows logo dissapears screen goes black and monitor says "no signal". but the pc is logged in and running in the backround.. to get the picture back i need to reinstall windows each time. please help
I have the same card, first try if posible with a another GF, if There is No black screen, normal screen, your new GF is most likley DOA .
You need to ask for a RMA.
