Every pc/laptop will only accept a certain amount of memory. Your probably overloading it. Check in your system info to see how much it can take. Also, make absolutely sure that you have the right memory stick for you pc!

Test your computer using a brand new hard drive. 1GB memory is enough. I am sure this is a software problem (messy registry or problematic apps or malware) or space problem (the hard drive is almost full).

Most RAM will work with each other, but the safest way to be sure is by checking the speed. On the stick that is in there now you should see a label that says something like PC2100 DDR. I looked up the specs of your computer and this RAM should work for it.

According to the specs of this laptop model, it supports up to 4 GB of DDR2 533/667 MHz memory using two soDIMM modules. This means that you will have to replace the 512 MB memory module already installed in your laptop, & replace it with 2 soDIMM DDR2 533/667 MHz memory modules, each of 2 GB capacity.

Either the RAM is not compatible or not inserted correctly. Try removing and reseating both modules, if no change try with only one stick then switch and try just the other to see if the problem is just with one. You could also try resetting the BIOS to factory defaults.
