Screen black after installing ASUS GTX 550 Ti on M5A78L-MLX PLUS

Screen black after installing ASUS GTX 550 Ti on M5A78L-MLX PLUS, I got Cooler Master Silent Pro M 600W, any idea to solve this?

Processor: AMD FX-8120 3.1 GHz
Memory: Kingston 8GB DDR3 (1333MHz - PC3-10600), two sticks of 4GB
Motherboard: ASUS M5A78L-MLX PLUS
HD: Seagate ST3000DM001 of 3TB, 7200rpm
Optical device: LiteOn IHAS122-04 B CD/DVD-RW
PSU: Cooler Master Silent Pro M 600W

When I take out the GTX 550 Ti it works normally but after mounting the GPU I got the black screen and I can do nothing not even access the BIOS; if anyone knows how to solve it, please let me know I'm kinda frustrated :(

Thanks in advance.

  1. I cant be 100% sure that its the GPU but it seems like you just have a defective card.
  2. Not really.
    As my one is the same with this problem :sarcastic:
  3. What you could try is downloading the drivers off the nvidia website, then plugging the card in.
  4. Thank you everyone!

    but I already solved this, the problem was my old monitor Samsung v550 I was running the test with this monitor and a friend of mine told me that the monitor should work in digital way not only in analog that's why I always had a black screen so I changed the monitor for the UN32EH5300F and it worked. :D

    Thank you for all your replies.
