The fan or heat sink burned out on my AMD Radeon HD 6700 card and after consulting with a friend I got the R7 250x.
I tried to install the new card but I get no video (at all), HDMI and DVI ports give me nothing. I've uninstalled the old drivers, installed new drivers, and increased my power supply to 600W. The card seats properly and the fan comes on but no video.
Oddly, the lights on my keyboard don't come on either when the card is installed.
that's DDR3 RAM.
Please, any help you can offer would be greatly appreciated.
