I have a dell dimension 8100. I am wondering if the motherboard is bad or the video card. All monitors that I hook the computer up to are very dark and the blue hue seems to be very pronounced.

Hello, make sure there is a green light on the front of the monitor, if not then no connection from pc to monitor, Make sure monitor is plugged in and powered up, and cable is connected into the pc. If all this is connected, then you either have bad video card, or motherboard for video or bad monitor.

Thank you for replying,
As per the diagnostic LED's, it is an issue with Video initialization failure. Your computer has onboard Graphics which is built into the Motherboard.
Video Initialization failure could happen if there is :
Unseated AGP card
Bad AGP card
Bad motherboard

As per your Svc Tag your system doesn't have AGP Graphics Card, Probable issue with MOBO.
This computer doesn't have a AGP Slot (Graphics Card Slot) to try connecting Graphics Card.
Need to repair/replace MOBO.

Thanks.

One of three things is the most likely culprit.

1. Onboard video card is either disabled or bad.
2. Cable is bad
3. Monitor is bad.

You can check the last 2 relativly easily by hooking the monitor and cable up to another computer to see if they function. if they don't then first try swapping out the cable (i say this first because its cheaper) then swap out the monitor.

To see if the video card is bad try hooking up a different monitor to the system. If the new monitor is not displaying anything then you most likely will need to put a new video card in the machine.

BTX mother board.

A beep code of 3-3-4= Video Memory(RAM) Test Failure that would explain why you get nothing on your screen the first thing you would need to do is disconnect your monitor and try it on another computer. if it works fine then the problem is your video card. If that the case and the video card is intergrated with the motherboard, you will need to repalce the motherboard --- Sorry-- Please vote me a 10 when this works

Try these steps: 1. Check the monitor settings. Access the On Screen Display (OSD) Menu System. Adjust the contrast and brightness using the control buttons in the monitor.
2. Run the monitor self test. Unplug the video cable from the computer (cable from monitor to the back of the computer). Usually it has a blue or white connector. Turn on the monitor alone. It should display the self test pattern (white, red, green & blue). If the images are dark in the self test, it is a problem with the monitor.
2. Rotate the monitor to face a different direction. This will help in eliminating sunlight glare which can cause poor picture quality.
3. Test your computer using another working monitor. If the problem occurs in a known good monitor, then it is a video card or motherboard (if your video card is integrated) problem.
I hope these options help.

if you have no image on the monitor when you hook monitor to other pc and you installed the video drivers for monitor and still no image then you got either a bad power cable for your monitor or your monitor is shot...get a new monitor... try testing again with a different power cable... if still the same... then monitor is shot... replace it...

According to Dell's list of light codes (available here), this means "memory failed to be sized or enabled". In other words, it's a memory issue. Dell suggests reseating the memory modules. I would recommend removing the modules, make sure the contacts are clean (use a pencil eraser to gently clean them if they aren't), and use compressed air (available in cans at office supply places) to blow any dust and dirt from the module connectors on the system board. Then reseat the modules, making sure they latch properly into place.

If the problem continues, you might have a bad module. Sometimes they act up intermittently. Or it could be a symptom of a developing motherboard problem. Try cleaning and reseating the memory first as that's pretty common.

Hi,
This might be problem with your with your monitor or videocard.
