Computer turns on, but there is no display on monitor.
My monitor stays completely black when I turn on the computer. I switched out the monitor with my other monitor (which works perfectly on my other computer) and had the same problem--black screen. Is the video card bad? I believe the video is built-in. Can I buy a video card and put it in one of the two open PCI slots?

Does the computer stay on or switch off?
If the computer stays on and the monitor completely switches off then it's a monitor power problem.
Make sure all connections are securely connected.
If the computer also completely switches off then it's more likely to be a computer problem.
If it's a monitor problem then the monitor will have to go to a monitor repair shop.
If the box does switch off then let us know to continue to troubleshoot.
Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.
Normally it's because the resolution is set too high for the monitor. This has happened to me when I switch a computer from a flat screen to a old "biggy-size" monitor.
try rebooting the computer and BEFORE you see the windows splash screen, start pushing the F8 key...this should bring up a menu...select VGA Mode...it won't be pretty, but once you're in..right click on the desktop and change the solution (try 800x600). restart the machine...that should work.
i think it can be the capacitor problem, open monitor an look for swollen capacitors. if you will find them swollen or
