what OS are you using?
192MB of ram is way low for any OS IMHO...I have 2GB....
since you state your cpu is running at 2.53GHz, I'm going to guess its a P4B running at 533 MHz and you are running windows XP....as noted your RAM is way too low for any good...you need at least 512MB and more like 1024MB to really perform....if my assumption of your cpu is correct, then you need RAM that is PC2700...and of course you need to verify that it is compatible with your system before you buy it....
So Long and Thanks for All the Files
