Remove old ram - Compaq Presario C700T Notebook

Hi,
Please check the speed in MHZ of old RAM and New 1GB RAM.
Some times if speed wont match this problem occur.
Remove old RAMs and add only 1GB RAM and start the system.

I hope it will help you.

Thanks for using FixYa.

Hello

This usually occurs when your RAM is faulty and can actually happen to all computers running many different operating systems. Aside from installing a new operating system to test out the RAM, you can simply switch out your RAM.


Turn off your computer if it is on. If you are experiencing the black screen regularly, there is a good chance that it will not allow you to boot up your computer fully without shutting itself down. If this is the case, your computer is already more than likely off. Remove the power cord from the computer tower.

Remove the screws that hold the PC tower cover in place with a screwdriver. The tower cover usually only comes off on one side, so gently remove the side that is capable, and place it away from the tower. Users with laptops need to remove the RAM panel from the underside of the computer. This gives you access to the RAM for replacing.

Locate the RAM that is attached to the motherboard of your computer. You will see clasps that hold the RAM into place, and you may see more than one stick of RAM. Remove all of the RAM sticks by pushing the clasps away, unhooking the RAM from the motherboard. Click your new, replacement RAM into place, and cover the tower back up with the cover, or replace the laptop RAM panel.

Hook up the power cable or place the battery back in, and power on your computer. You now see that your computer is working without the black screen appearing. If you have more than one stick of RAM, turn the computer off, and remove the power cords and battery. Insert one old RAM stick, and cover the tower back up, replace the power cord or battery, and turn on your computer. Check to make sure it does not present you with the blue screen. One by one, reinsert the old RAM sticks into your computer, and test your computer for stability. Once you are presented with the black screen, remove the last old RAM stick that you inserted, and your screen problems are gone.

Remove both sticks of RAM. Insert the "new" RAM where the "old" RAM was, and see if your computer reports "zero" RAM or 1GB of RAM. If the latter, put the "old" RAM into the "second" slot, and see if the detected RAM is the sum of the two sticks.

Did you remove the "old" RAM, or did you add the "new" RAM to the old RAM?

Try using your computer with ONLY the "new" RAM installed.
Try using your computer with ONLY the "old" RAM installed.
Try using your computer with the "new" RAM in the 1st slot, and the "old" RAM in the 2nd slot.
Try using your computer with the "old" RAM in the 1st slot, and the "new" RAM in the 2nd slot.

Remove the "new" RAM.
Look at the labels for PC2100 or PC2700 or PC3200,
or for DDR266 or DDR333 or DDR400.
Compare with the label on one of the "old" sticks of RAM.

Be sure that the labels on the "new" RAM are "equal" or "higher" than the labels on the "old" RAM.
For example, if the "old" RAM are DDR333, then you can use DDR400, but your computer will not accept DDR266.

Reinsert one of the sticks of the "old" RAM.
Does it still beep multiple times?
If not, then the new RAM is *NOT* compatible with your computer.

it is better to remove both the old RAM and fix the new RAM in the upper slot.....
you can fix one of the old ram to the other empty slot, but sometime timing conflict may arise between two Ram and the system may not function properly...anyhow if both the new and old ram are of same operating frequency you can use both....

Some facts about memory. Newer machines seem to favor matched ram. This means you want to buy memory from the same manufacturer with the same specifications. It used to be in the old days that ram was pretty much ram. It didnt seem to be all that picky about being matched and maybe that was because most of the ram timings were standardized? There were exceptions of course but today there are many more options in speed/timings available from ram manufacturers.

Some things you might like to try. Make sure the ram is for your pc and remove the old ram entirely and put in the new RAM. Does the pc work? If it does and If you have the manual for the computer or motherboard, see if there is a certain slot for slower ram. Or trying moving the new ram to other slots.
If the new ram does not work by itself when you remove the old RAM entirely then the memory you got could be bad for whatever reason. Remember this stuff is pretty sensitive to static and other stray electrical currents.
What I do for customers that want more ram is I replace ALL of the ram with a matched set of memory they want. This minimizes returns and sometimes odd behaviors that are hard to track down.

the problem is with the new ram.
its phsically damged.
may be little bit that you cant see it.
try checking the other 1GB ram.

Is it an upgrade of RAM? If so, remove the new RAM and test the default RAM if you still have the problem. If the problem is solved, just reseat the RAM or better yet, remove the old RAM then just put in the new RAM just to identify which causes the problem.

Hope this helps.

Hi Daisy,
You need to remove one of the old RAMs but would like to remind you that different brand of rams with different type of memory would cause a conflict in the future. better remove both your OLD RAM and replace only that new 1GB ram, unless one of your old rams is a 1Gb also with the same brand.

let me know what you did. :)
