Computer is working for 5 minutes, then no display

Disconnect it from computer and power. wait 15 minutes and plug only the power back in, press the power on button. The monitor may display a message that there is no signal or something like that. If that happens the problem is either the cable or the computer. If you get no message then look for the menu button and press it to see if any thing appears. If not find the manual on line and read it. Many times monitors get over-driven by computers to the point that they can't display OR they self destruct.


OR

Another way is to just unplug everything computer and monitor for 15 minutes. Plug in monitor first then plug in computer and press the power button, the display should display the booting information if the cable is good and the monitor is good.

You will need to adjust the refresh rate of your system.

1) Right click on the desktop and go to properties.
2) When the Display Properties window opens go to the Settings tab.
3) The go Advanced.
4) Once ni the advanced screen go to the Monitor tab.
5) Under screen refresh rate select around 60Hertz. (Make sure the box next to "Hide modes that this monitor cannot display" is ticked.
6) The click OK. And OK again to exit Display Properties.

Hi. Check the cables if it is firmly connected to the video ports. If nothing happens, try removing and reinstalling the video card then reconnect the cables. It works wonders!!!

^_^

yes start the computer then keep pressed the key F8 untill the display comes then hightlight the option last good known configuration and select the problem will be solved

check your rams that may not properly installed.

if that is installed correctly then change BIOS battery....


no prob.

Try disconnecting the monitor from the video connection.
Disconnect the power source and allow to set for several minutes.
Plug in the power source only and see if you recv. a no signal message on screen.
If not, you most likely have a bad display board or back light problem.
If you do recv. the message, you have a problem with your video card.

You should see both monitors indentfy the one and change it to a lower resolution.

The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:

Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.

Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

These messages are normal when the computer truly goes into suspend mode or loses the video signal (such as when the computer is suddenly turned off).
If the monitor displays any of these messages when the computer should be displaying video , do the following items until an image from the computer appears:

1.
Ensure the computer is really sending a video signal. To bring the computer out of suspend mode: move the mouse, press the spacebar, and press the suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).
2.
Ensure the video cable is connected (and connected to the correct video port).
3.
If you are trying to view video from a set-top box, DVD player or similar device, use its menu system to set the proper video output channel so that it matches the video connection are using. For example, if the monitor is connected to a satellite receiver via a second HDMI connection on the back of the receiver, select HDMI-2 (or similar) using the remote control for the receiver.
4.
Turn off the monitor using the monitor's power button and then restart the monitor.
5.
Cycle the power on the monitor as follows:
1.
Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
2.
Unplug the power cord.
3.
Wait 5 seconds.
4.
Plug in the power cord.
5.
Press the power button on the monitor to turn on the monitor.
One of two things happens:
1.
The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
2.
The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution.
6.
Adjust the Windows display resolution to a setting that is compatible with the monitor:
NOTE: The native resolution setting for your model of monitor can be found in the Monitor User Guide, the monitor's product packaging, and product specifications.
1.
Restart the computer and press F8 repeatedly after the first logo screen.
2.
Select Safe Mode .
3.
Windows should open showing a Windows desktop with lower resolution and fewer colors.
4.
In Windows Vista, click Start , Control Panel , and click Adjust Screen Resolution in Appearance and Personalization.
In Windows XP, click Start , Settings , Control Panel and then double-click the Display icon and select the Settings tab.
5.
Move the slider bar until the native resolution for the monitor is set, click OK and restart the computer.
6.
If the native resolution is not available from the slider bar, click Advanced Settings , click List All Modes (from the Adapter tab), select the resolution, and click OK .
If the native resolution setting is not available as a selection in Windows, you can temporarily use 1024 x 768 to complete these steps. However, you should update the graphics driver on the computer. Updating the graphics driver can provide more display resolutions to Windows; possibly including the native display resolution for the monitor.

7.
Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
*
If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
*
If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.

your monitor is telling you it's on it's last legs..either that or your compaq has a bad video section. either is more vital than a video cable being loose.
