But I don't think that will make any difference with my problem. Anyways I know its good idea to use system as normal user. > Step 3 - performance is "very very poor" is not a descriptive problem. > What *exactly* is slow?

GNumeric Save takes 2-3 sec and more as you use it for sometime 5. In Openoffice apps opening Presentations, Docs, Spreadsheets takes time 2-3 sec 6. If system is running for long time, VLC, Mplayer fail to show video only audio is available. Need to restart XServer or sometimes reboot to resolve this issue. . . . I do see a large Hard disk activity (HDD LED) while doing any of these tasks. But CPU usage never goes to 100% and I don't think anything hangs...
