Since yesterday Every time I turn on my computer my monitor displays no input signal for vga and dvi and monitor goes back to sleep.
Today when I turned on the computer everything seemed noramal the monitor worked fined.
The Windows log on screen appear and then the desktop appear fine like nothing, but after a minute the monitor went back to sleep and againg no VGA/DVI signal input!!!
I already tried a new vga cable but still the same problem. I can't even boot into safe mode nothing!!! MONITOR goes to sleep imediately!!! I have turn the computer on and off a dozen times and still nothing!!
Is it the monitor that is bad or is it the onboard vga port?
