Not sure this post is in the right section but here goes. My Monitor goes black a couple minutes after I start my computer. Everything is working fine and then it just goes black. The power button is still green like it is getting a signal. It isn't going to sleep or hibernating because it happens when I am working and won't come back on. Any suggestions?
It sounds like the monitor itself may be having a problem. If you monitor has DVI and VGA inputs try switching to the other input and see if it still does it. Use a convertor on your graphics card if you have too. It maybe whatever input you are using has developed a fault.
