Monitor/video card

By jamforj ·
I recently aquired a windows 98 box. When I turn it on my monitor goes from amber to green but I get no video. I chaanged out video cards and I get the same thing. It recognizes a monitor is present but the screen says check your cable or power cord. This same monitor works fine on any other box that I have. What could be the problem?

First you can check the memory to see if it inserted securely and then to clean the contacts with alcohol.
Boot the computer with a startup disk and boot into safe mode check the drivers for the video card
Check the display and see if adjusting the settings to SVGA will correct the problem,you should also check the refresh rate to see if this setting is too high.
Check the power manage and see if disabling it will help
Check all cord and adapter connector to make sure they are secure

Boot into safe mode.(press and hold the CTRL or F8 key until the Microsoft Windows 98 Startup Menu appears.) Set your display on 256 colors and 640x480 and Refresh Rate at 75 or lower. Boot normal.

Does the main board have on board video if so disable it to add your own card. Can you boot into safe mode and get a normal screen? I would try clearing the cmos and using defaults until you get a clear screen. It sounds like its loading a last config.

Do you get the BIOS POST screen, and the Windows Logo screen?

If yes, you probably have a video / monitor refresh rate conflict.

You will need to boot into safe mode as one of the other respondents suggested. However, you need to go to diplayproperties, and accept the safe mode display settings of 16 colors and 640 * 480.

Check the BIOS settings related to video, primary display, IRQ, palet snoop, etc. I can't give you specific recomendations without knowing more about your MB andvideo card.
Remove all display driver files.
Update the mother board chip set driver files.
Install the correct video card driver.

If you get no video at all, not even the POST screens, then you have a hardware problem.

Make sure that the processor and memory are installed correctly.
Make sure that the power supply and drive cables are installed correctly, and seated.
Make sure all plug in cards are seated.
Check the CPU voltage and clock jumpers.

Still no video?
Clear the CMOS. Either set the clear CMOS jumper, (you may need to turn on and turn off the system to clear the CMOS) or remove the battery for several minutes. (again, you may need to power up to clear the CMOS)

Still no video?
Strip the system down to the bare minimum.
CPU, minimum memory, video card. No drives or other cards.

Still no video?
Now it's time to decide if this system is worth salvaging.
Inspect the MB for burnt or physically damaged components.
Check the power supply voltages, swap out the CPU and memory.

At this point, if you have not found the problem, it is likely that the MB or BIOS is fried.

Hi
Can you see the POST the first text screen when you boot Then check first if you can boot to dos and have no problem. Reboot press Ctrl and choose the option to boot to dos.This will tell you that there is a problem with windows (driver, refreshrate ect ... .Boot to save mode and use the software it came with the video card to ajuste the refresh rate. or re install driver.(check the driver with the other pc and down load it fro manufacturer).
There is a little light near your monitor's on/off button. This is called the "synch light," and it usually displays three states: 1- Dark means that the monitor doesn't have any power or can't function.2- Green means that the monitor it is receiving and displaying the signal from the video card.3- Amber means that either there is no detectable video signal, or that the monitor is intentionally sleeping.Your problem Usualy happen if there is a problem with the cable (unseen cut specially near the connection,visually inspect your cable for damage ) , video card (malfunctione, driver problem), refresh rate is not in the limit, and there is a magnetic or electricity near the monitor.
1- First try another monitor in the same pc and see if you have the same problem.(use agood cable) 2-Make sure that the voltage is right for both CPU and monitor. Check setting on your BIOS and the other CPU where the Monitor worked.take CPU to the envirnment of the CPU wich work use all the same cables, out let ect ... .Check if your monitor support Energy Star these seting could be stored by video card and the BIOS.

Good luck

Mohamed
