Can anyone help me with my problem?
I have a sapphire hd 7770 ghz edition 1gb gddr5 and ASUS Motherboard P8H77-M LE, I've been using it for more than a year and it works fine, but then one time, I left my PC and it went to standby mode and when I was trying to return the display, it's just all black. I tried to restart my computer (thinking that it will solve my problem) it displays nothing (no signal) but I'm sure that the PC boots and it even reached windows desktop because I hear the audio makes the sound of windows logon. I've tried reseating the GPU and RAM but it doesn't help me either. I tried my GPU to other computer, it has a display and works fine, then I tried other GPU on my computer, it also has a display and also works fine. Is it a motherboard and GPU compatibility issue? But my graphics card works with other computer and my computer works with other graphics card and I've been using it for more than a year. I'm sure that my video cable, adapter (VGA to HDMI), and monitor works fine. My GPU is properly seated when I'm putting it into my motherboard, and I dont forget to connect the 6 pin power cable connector to my GPU. My PSU is Cougar RS 650W,
