I have a desktop system and is quite old. I had purchased it around 2 and a half years ago. My system operates on windows xp home edition operating system and has an intel dual core processor in it with a 160 GB of hard disk space and 512MB of RAM. Since many days I am facing lots of issue in my system , it is working very slow and I get very frustrated whenever I use internet on my system , because the browser takes a long time to browse even simple websites such as google . Can any one please help me in fixing this issue as I am not used to such slow speed , because I used fast and powerful systems in my office.
