I have been having trouble with my monitor, for a while it would go to sleep and when I'd wake it, it would go black and I'd have to turn it off and turn it back on, it would flash and go back off. I'd continue to turn it off and on until it seemed to "warm up" and then it would stay on. It hasn't done that in a while, but now what it does is when I wake it up from sleep, if I open my mail or a webpage right away, it will go black. If I turn it off and back on, it flashes. If I can get the mail or page to close by trying to place my mouse where the "x" would be to close the page and then turn it off and back on, it will stay on, as long as the page is open, it only flashes. If I wait a bit and don't open anything for a minute or so then I can open whatever and it doesn't go black, it happens only when I wake it from sleep and open something right away. Does this sound like my monitor is going out or is it possibly a graphics card issue? I run Windows 7 and my monitor is an LCD probably 6 to 8 years old.
