Occasionally my monitor will go to a screen saver, where the screen goes black you know? except that when I return, it does not reshow windows, instead giving a "no input signal error". When I restart the computer, it is usually fine, although sometimes when I restart, and when I just start my computer up from shutting it down, I get this error. Like I said, with a restart everything is back to normal, but it sure is annoying. My computer just started this problem after I installed a new sound card and upgraded my memory. I uninstalled the sound card and opted for on-board sound, but this still happens. I have moved and unfortunately don't have my old memory anymore to test it with....could this be the issue or might it be a motherboard going bad or an issue with the power supply?
