My desktop computer is always "on", & the monitor either displays a screen saver or "rests" & is black until I touch the mouse & the page with my icons comes up. Recently, however, the monitor has remained black when I tried to log on, & no amount of clicking would help. I tried turning off the computer, unplugging it, replacing the batteries in the wireless keyboard, nothing worked. I noted that if I pushed the button on the monitor to turn it off & then on again, when I turned it on & held it for a few seconds, the monitor would flash on quickly, showing the page, then immediately go off. But it doesn't even do that every time. Could my wireless keyboard & mouse be an issue in this? This has happened several times recently, & when the screen does "come back", it is always at random. But it takes longer to do so each time now, & I don't know what to do. Is my monitor at fault? The hard drive? I would be so grateful for any help I can get! Thank You!

Have you tried to update the graphics driver ! Thy that first and then post back with the verdict.

Step 1 to determine if the monitor is faulty. With power off, disconnect the VGA cable from the PC. Now connect power to the monitor and press the On button. Do you get any display such as "Signal Out of Range" or "No Input" Is this a CRT or LCD monitor? It is highly unlikely that your problem relates to any of the things you mentioned such as harddrive, or wireless keyboard. It is more likely to be either an internal fault in the monitor, or your graphics card. System specs for a Dimension3000 indicate it came with a CRT monitor and has onboard graphics. The simplest thing you can try is to connect to a different monitor. If the problem persists then I would suspect motherboard failure. Goin' Fishin' (Some day)

Thank you for the suggestions! I thought I'd try the easiest thing first, & I think it worked. I tried a different monitor, & here I am, back online with no black screen to deal with! So, at this point, I think the monitor had to be the problem. I will go buy a new monitor tomorrow, & if it happens again, then I'll have to go the graphic-card route. I really appreciate the responses to my problem. I am glad that one good thing has come out of this -- I found this site!
