So i have this aoc monitor that only has dvi and vga... whenever i turn off my computer before i sleep.. waking up in the morning and turning on the pc and then had this problem that my monitor led indicator is blinking blue light.. in a loop ive tried replacing cable except for dvi.. transfering to another dvi port on my video card works last week but today it did not work.. tried turning off for mins and then turning on but it isnt helping..
