OS not changing RAM installed

[nessers]

Hello, hopefully someone can help me.



I have a Dell Dimension Dim 3000 computer, with OS: Microsoft Windows XP,

Home Edition, Version 2002, SP3 (32-bit). When I got the computer in 2005,

the original RAM was 256 mb. My dad had installed 1 GB, which I forgot about.

Lately my computer has been horribly slow. Did virus check, disk defrag, and

deleted programs.



System is showing only 256 mb, but my BIOS recognizes any change right away.

Right now it read 1024 mb, but Windows is not changing at all. I'm not even

close to the maximum this computer can hold.



Anyone have any ideas as to why it's not reading it?

(This seems to happen to a lot of Dells).

This can happen if the RAM modules are not in the correct slots. Another

possibility is defective RAM or incorrect RAM or mismatched RAM.



Please inventory and identify these modules for further assistance. Also

report which slots they are in.



Finally, with certain Dells, you need to enter the BIOS and set OS

Install to Off (which is the normal default) in order for more than

256MB to be recognized. You might as well try this first.
