Sheesh! Only 160GB of memory and a single GB of RAM... Got to upgrade my PC, even my processor is telling me so since last couple of months..
I am running XP as my OS and 2GB of RAM just about does the job okay depending on what applications I'm running.
Reminds of my slow notebook that had Windows Vista. It was very slow. One day suddenly I thought of checking the amount of memory it was just 1GB. I was surprised. I opened the back side. Turned out that the memory module was loose. I got my 2GB back. It is fast now
