    For a while now I have a small problem with my desktop and it is starting to annoy me. The following things happen:
    -When I start my computer and monitor then the monitor works for about 10 seconds before it turns black. Usually this is just after logging in, but if I don't log in fast it turns black at the login screen. It stays black for a minute and then everything is back to normal.
    -Sometimes the monitor thinks it has no video imput in this minute and I have to restart the monitor or computer.
    -When my computer has been on a while and I decide its time for a little break I turn off my monitor. When I turn it back on again after 30 minutes the same thing happens.

    Does anyone know what the problem might be? It feels like a waste to have a computer that can start up in under 10 seconds and then have to wait for a minute before the monitor works properly.

    1) Stop turning the monitor off! When you do, the PC detects that there is no monitor and way more than a few do a lousy job of redetecting it if the PC goes to sleep! Learn to use this instead:
    2) Do WinKey+R and type POWERCFG.CPL into the run box. Change the plan settings so there is more time before the screen goes blank.
