Call me LEWY
Maybe?
I'm replacing my Nvidia gt 610 with a radeon hd 7770. My TV won't display anything with the radeon card connected. I see no BIOS or anything.
If I take out the radeon card and use onboard or Nvidia graphics, it starts normal. Also, if I connect both Nvidia graphics card and the radeon card, I get a normal display through my nvidia card (did this to test if it is a power issue).
Specs:
Intel I3 processor.
650W PSU.
Radeon HD 7770 (I think 450W).
500GB hard drive.
8GB RAM.
