Hi, im having this problem :
I have HP probook 4730s which runs intel graphics and amd. While i was playing game on amd card my notebook froze and i couldnt do anything so i did power shutdown. When i turned onnotebook on it was loading windows and then froze up again. I have tried restoring windows and launching startup and both didnt worked so i end up doing clean reinstall of windows. Now when i try to install graphics drivers for AMD i get black screen with underscore in the upper left right corner. I have tried to do clean reinstall of amd and i tried installing older drivers but it doesnt help. Is my AMD graphics card dead?

It's impossible to say. You will need to take it to a technician to determine that.
