    RADEON R7 240 700M 4GB Not Working with my Dell Desktop

    motieian

      Recently purchased a RADEON R7 240 700M 4GB, and installed it on a Dell XPS 8300. I have recently upgraded the PSU to a Thermaltake - TR2-600NL2NC ATX12V & EPS12V Power Supply which outputs 600W.

      Once turned on, everything seems to be working inside as I hear the HDD and CPU fan working; however I have no signal to my LCD. I can't see anything and the screen wouldn't just show anything.

      Once I put the old graphics card back in the computer, the LCD lights up and works.

       

      Would anyone know what's wrong?

       

      Thank you
