No Video Output - New RAM - Tried Most Things


I recently changed the RAM in my machine. The computer boots but does not have any output or any beeps. Just a black screen. I have removed the RAM sticks individually and still no luck. I have tried putting in a video card to and that hasn't solved the problems. I dont know what else to do.

Also when holding the power button the system will not shut down.

Are you able to help please?

    I have indeed tried the original RAM that the machine was running fine with beforehand with no luck.

    I have tried taking out the CMOS battery each time trying the RAM.


  • ShauneyB Feb 15, 2008

    I have reset the BIOS and the CMOS each time I made a change. I have changed the apropriate BIOS settings to display out of the right adapter each time.

    I have tried the new RAM, the old RAM and some other RAM.

    I don't know what else to try!

    Right it seems there is some confusion to the problem when reading it.


    Added some new RAM to my computer. It is withing the motherboard specifications.

    On booting the machine after the swap it would not POST.

    Since then I have tried the original RAM in every combination, different RAM in different combinations and with single sticks.

    Each time I have tried to change some hardware since the problem I have reset the CMOS and taken out the BIOS battery.

    I have also tried a VGA video card and changed the apropriate BIOS settings to the right output.

    Each time the hard drive and processor and all other hardware is sounding as normal.

    Still no luck!!!

    Any other ideas?

    I stupidly switched the RAM while the laptop was hibernating. I did not take out the battery and thought the thing was totally off. Afterward, no video. Replaced the original RAM without luck.

Without sounding silly. Have you tried replacing your new memory with your old memory? Just to see if your Pc boots normally. This will narrow down the root cause. This board only will only handel this type of memory.
Single channel, unbuffered, 2.5V DDR266/333/400, (2)184-pin DIMM sockets, max 2GB

    Should have come back sooner. Sorry. Ok, you mentioned you installed a video card. I ask that because your board has a intergrated video card. You need to make the correct changes in the bios. Taking out the battery to reset the bios settings is a good idea but you also need to move the cmos jumper position from pins 2&3 to pins 1&2, (pg. 4 in your manual) as well as removing the battery. Than return the battery & set the jumper back to pins 2&3. If your newer memory is within the spec's I listed above & your bios is set to AGP your system should boot & run.

    Ok, dwn to the basic's. Are you saying the Pc just lost display one day (no changes to system)? Than you tried other things like new memory ect? When you lost display was the rest of the system still running, like hard drive seemed to be running, floppy disk flashed at startup, cdrom light lit & keyboard lights still lit at boot up? Did you try putting memory into different slots & only use 1 dimm?

  • Mike Peluso

    It is still the basic's, you may not get a beep error code because your video is on board but you do have a spare AGP slot. So add a AGP video card & set your bios to goto AGP first. Also try another monitor just to cover all base's.

Gateway wont startup. One beep followed by two short

Not sure where you got your information on the error codes but it is partly correct, it is video related, but it isn't the video card but rather the memory location in the ram that is used by the video card. You could try to remove the ram memory clean and re-seat it on the mother board and see if that fixes it, or if your motherboard has two or more ram memory modules, remove the memory and switch which sockets you replace them in (make sure you keep track of the original position of the modules because on some rare motherboards you have to use the memory in a picky order) after mixing up the memory modules check for a boot again, if this corrects the booting then one of the memory modules is defective and may need replacing. Note when you take your memory into a computer shop be sure to use a static bag and proper static precautions.

After installing new ATI HD4670 video card on my Gateway zx6810 I boot system hear no beeps computer powers on but screen is black


Is this new video card the only video source on the PC (i.e. there is no other VGA connections on the PC)?

Without knowing the make and model of the PC, I will list the most common issue when replacing the video card in a PC.

1. Connect the monitor to each available VGA connection and boot the computer - to see if any VGA output is working

2. When you find a working VGA output, go into BIOS and change the VIDEO settings to either allow BOTH the onboard and add in video OR allow the add in video only. Save the changes and turn the computer off.

3. Move the video cable to the add in video card, turn the computer on and see if the BIOS is using the new Video card

You should try first the onboard VGA output of your motherboard to be sure if the Video Card is damaged. And to be sure f your motherboard is working. Keep on touch

No video output. bleeping every 7 seconds

This beeping is usually caused by a bad Memory or Ram chip. The memory is the chip that is inserted in the purple slots in your display picture. Remove them if there is more than one and replace one by one. Make sure they are firmly reseated or it could damage the motherboard. Make sure both clips on either side are fastened properly.

Try booting computer again. If it continues beeping the memory module may be bad. Replace it with a new one.

Thanks and good luck!

Asus mb wl300 amd 64 4000+ won't boot to bios.

To make sure it isn't anything else, pull all cards, and drive cables from the board so the only thing left connected is the power connectors to the motherboard, the speaker, and the power button. Pull all the ram cards.

Now power up the computer. If you hear a series of beeps then the computer recognizes there is no ram on the board. At this point I would take the power supply out and have it tested. If you do not hear a series of beeps I would still have the power supply tested as it could be the 12v is fine but the 5 and 3.3 volt side is bad.

If power supply tests good then I would replace both the motherboard and processor. You take a risk of burning a new processor if it's the motherboard causing the problems.

Computer on, but no video output

sounds more like your motherboard,

unplug everything so all you have is ram (1 piece), cpu + harddrive(essential parts) no sound card, use on board graphics if you have it and if no luck then more likely the motherboard. Ihad a works machine go down before christmas with the same symptons and the problem was the motherboard

hope this helps
