I have a Dell desktop. My montor won't turn off. When I turn off the computer, the light on the monitor remains green and then it starts to change color repeatedly-from red to blue to white, etc.

If it works fine otherwise I don't see a problem here. If these lights bother you just turn off the monitor.

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

I just have a OPTIPLEX SX280 and try to connect to my old montor (VGA), when I turn on power it seem run starting but the it show up on monitor screen "can not display video mode". What is that...


When you first power on the computer tap the <F8> key to bring you to a menu that has the option of running in safe mode. If the computer boots up in safe mode and you are able to see the display on your monitor then your current video drivers are not supported for the old monitor.

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

Ok when i turn on my aoc monitor colors like blue green red white pop up i can never use my desktop


I would suggest that you try another monitor. If the monitor continues to light up with these colors and you do not see your computer desktop, then I would tend to think that your computer may have a problem with the video card or driver. Do you get a message on your montor with words like "no connection" or "No signal". If so, this means that the monitor is getting no video signal from you desktop. Try disconnecting your monitor plug and removing power from the monitor in an attempt to reset the monitor. Try also to turn off and unplug your computer. Leave the computer unplugged for about 10 minutes and start it up again. This may reset your computer. If you monitor video cable will disconnect from the monitor, you may want to get a new cable. These cable do go bad sometimes and are available and inexpensive on Ebay.com

Try these ideas and let me know how you do.
