PC Trouble

While at work I open at least four to five files. Aside from that there were also websites running, yahoo messenger, Outlook Express and other applications I'm using. My office PC still runs so smooth even all those apps are open. My past time are downloading music and other cool applications although sometimes if I find that the apps are not useful I will instantly delete it.

I believe my PC is getting so weary from its two years continuous work with no proper maintenance. I noticed that for two weeks, my PC is running very slow especially when I opened multiple applications… or sometimes even if I am working with only a single file and one open website. There’s no difference in the PC’s performance whether it is loaded or not. I tried to defragment it and perform a disk cleanup
