Previously it works fine. Recently i was playing guitar which was connected to my computer. About half and hour later my display doesn't show anything. A black screen pop ups as like when computer goes to sleep and it never came back. I changed vga cable from graphics card to motherbord and computer starts. But when its connected to graphics card it doesnt display anything. But the computer starts cause i can hear the logg in sound. I have amd hd6570 ddr3 2gb graphics card
Thanks in advance to those who help
