1 Long Beep accompanied by Monitor not Turning on...

I recently bought two new sticks of 512 MB RAM to replace the old two sticks of 256 MB's. Both sets of RAM were the same type... PC 2100 DDR. When I finished up replacing the RAM, I went to turn on my computer, but the monitor would not turn on. After a few tries of taking the new RAM out and putting it back in I went to install the old 256 MB's of RAM. But this time I heard a long beep coming from my Computer (about 5-7 seconds estimated.)

I checked online and found out that it had something to do with my RAM or my Video Card. But to me that does not make any sense, because I put the old ram back into the computer, and the same result occurred.

Is there something wrong with my Motherboard? Or some other problem that I do not know about? Any assistance is greatly appreciated.

Good Day ! I exactly know why can not work your aging memory since meet often with such situation in my operation. Do Not worry this easy solved problem. You must to clean from dust ALL contacts on motherboard and memory modules, use pressured air, ore vacuum cleanser, be carefull.
After that you must to clean yelloy "pins" ("contacts" ) on the both sides of the each modules. Use for it fabrics ed by alcohol. then contacts will shine, put it back to you mother board. I recommend also remove and install 5-6 times in slot for better results. Same procedure you can do with video card, it be very useful.1 Long Beep accompanied by Monitor not Turning on. - 75851e2.jpg

Hi there
what you can do is to power down the computer and remove the power supply cord and open the case, now find the power supply cord that goes to the motherbord and unplug it now press the computers on button and also a reset if you have it. than plug in the cord back into the mother board and doublecheck that your memory modules are inserted all of the way i would try only 1 at a time and see if the the computer will now boot if so than try to add the second one and see what happnes you should get a memory change message ok. please try this and let me know how this goes for you , there is more that can be done but this is the easiest thing first
best regards mike

I have a Packard Bell desk top PC In 2006 I Installed windows vista I noticed I needed a 512 ram as I had 256.I bought a 512 ram I knew were to install It ,I took the 256 ram out and carefully put In...

You put in the wrong type of memory. Put the old 256 back in the computer should power on with no beep code(or all good beep). If this is correct make sure to obtain the same type of memory as the 256. Also both slots must have the same RAM. You cannot have a 128 with a 512. They should both be either 128 or 512.
If you are using Vista you should have a minimum of 1g RAM.

Make sure you have the memory installed correctly. Those beep codes identify it as bad memory. Try the old RAM.
Good luck with this.

Sorry for the delay in my response.

Your computer will accept a maximum of 1 GB of memory. If both memory modules are the same brand and part number then it is possible that one of the sticks are bad.

Try each 512 MB memory stick in the first memory slot, without installing a second stick. This will troubleshoot to find out if one of the 512 memory sticks are bad. If both check out ok, then the problem is with the video adaptor.

Have you tried adjusting the refresh rate on the monitor as I described in my first response?

My final possible solution would be to upgrade the bios. Below is a link to the webpage for your computer system. You will find links for troubleshooting guides, driver and software downloads, product specifications, etc. If you click on driver downloads, then choose your operating system, you will be directed to a page that should provide the latest ROM (bios) update.

Sdram capacity

its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
