Hello I' ve installed a new ATI RADEON Model No : HD 545X- ZC, Part No : HD 545X- ZCH2 and while i was installing the drivers from DVD, i got black screen with cursor blinking. After that i removed drivers and downloaded from AMD site and installed them. Same results. Monitor is connectted via vga and indicator has green light. Then I connected via HDMI with my 37inch LED TV and same results.
