Ignore the G: and the I:
Im gonna take them off as they're not mine.

Still my PC isnt fast enough….I guess thats coz of the slow processor speed. But still its good.

Hi Shan, I've been away for a while, and may still be away episodically for a while. You've sure worked hard to get your machines up and running well. As to this most recent PCPitstop Full Test, please follow the recommended "Customized Tune-up Tips". In addition, If you are able, please "disable" (via MSCONFIG) nVidia Driver Helper, Creative PLugins, and Starwind Alcohol. Post another fresh test after making those adjustment, if you like, but I think you will be up and running as well as can be expected for that machine. Best Regards
