How do you upgrade the RAM from 64MB to 512MB in an old Compaq Presario desktop computer?

Answer 1

Upgrading computer RAMIt depends on exactly what model it is (and there are a lot of Presario models -- see http://www.archmemory.com/index.asp?PageAction=VIEWCATS&Category=26215).

If you find your model listed there, click the link and you will see what the maximum amount of RAM your machine will support, and how many memory slots you have. If your computer only has two slots, then you'll need to pull out the existing RAM and insert two 256MB modules in their place.

Assuming that you have the proper amount of compatible RAM, the actual steps are:

1) Turn off and unplug your computer. Remove any external devices if necessary.

2) Open it up (this may require a screwdriver).

3) Unclip and pop out the existing RAM modules.

4) Carefully insert and secure the new RAM (this step can require a surprising amount of force, but make sure that the modules are aligned properly).

5) Close it up, plug it in, reattach whatever else you may have removed.

6) Turn it on and check to see that your new RAM is being recognized. (If your computer fails to boot, odds are good that it's not. Power down, unplug, and recheck that the RAM is properly seated. If you're sure that it is and the computer still doesn't boot properly, then your new RAM is--for any one of myriad possible reasons--incompatible with your computer. Or it could just be "bad" RAM, but verify compatibility before jumping to this conclusion.)
