keeping computer fast

what is the ram that u use?? i dont think u need to clean every thing always if you have a good ram.... defragment it regularly after downloading or installing something... and keep your desktop clean and minimise all the tabs that you are not using so that is saves some space on your ram.....

I normally use the utilities that come with the Operating system they work fine for me and I haven't had any problems

If you are in Windows specifically XP, here's my simple ways to get your computer a little extra fast. Delete those unnecessary start up programs in msconfig, use ccleaner software (recommended), disable unused services, clean your desktop, if possible do not use wallpapers and use the classic theme for windows (no eyecandy).

Hi I'm also using 1GB DDR2 633mhz RAM. I also use CCleaner but I only clean the registry once a month. (always save the back up incase of instability) My advise is only Defragment your drive once a month. Someone in this discussion suggested defragmenting after each install/uninstall but I advise not to do that. It's over doing it and will just add a lot of read and writes to your HDD. For software I have AVG antivirus 8, and spyware software that I'd prefer not to name. ^-~ I also don't use the windows defragmenter, I read there were much better options out there so downloaded something else. ALWAYS get the latest windows updates. I have yet to slow down my two computers or get any malware on them, and I use this old laptop for testing.
