My dell inspiron 2400 pc will not start up


If the power light doesn't come on at all, it could be the power supply is dead, or the power switch is defective.

Check to make sure the power cord and power supply cables are securely connected.

Here are some diagnostic tools for DELL computers.

Blank screen with blinking cursor on Dell desktop


First step is to make sure that nothing is plugged into the computer except a power cord, keyboard, monitor, and mouse. If it still does it, even unplug the mouse, because a mouse going bad can easily cause what you describe. If it still does it, try a different keyboard.make absolutely sure that nothing else is plugged into the computer.

Dell monitor flashing green power button black screen.


Your computer is in sleep mode, a low power mode that conserves power by turning off the screen and hard drive.

Push the power button on the system and the computer will resume.

If you don't like this feature, you can turn off sleep mode in the power options in Control Panel

When I turn my comp on, I get the Dell screen, then a black screen with a flashin cursor. When pressing f8 for safe-mode, nothing happens. Just a black screen with flashing cursor. Please help


Unplug all external USB devices to your computer and power it back up again.

If you can start the computer, then you probably have a faulty USB device connected to your computer.

Are Dell monitors not compatible with older HP Pavilion Computer? I tried to connect my HP CPU to a Dell monitor and it will not recognize it at all.


It shouldn't make any difference which monitor you are connecting to any computer. In fact, I am running a 19" HP Flat Panel on my Dell Dimension 2400 right now. It is NOT a wide screen monitor as the Dell built in graphics card will not support the RESOLUTION RATIO required for the wide screen. Check what setting is "native resolution" for your monitor and see if your graphics card will support it. If not, using your old monitor, try different resolution settings. Right click on your desk top, click on properties and that should bring up the display properties box. Try a lower setting as larger settings are the ones that will give you a black screen. It will probably give you a smaller picture on your old monitor, or perhaps smaller or larger icons on the desk top. Accept the new settings, turn off your computer and switch monitors, and turn your computer back on. If you get a picture, but it does not fill the whole screen or the icons seem too large or small, then go back into properties from the desktop and try a different resolution ratio until the picture seems correct.
