How you can make computer to run work quickly?

if you got an old computer that's running slow you can either run an cleaner tool like ccleaner or you can format your hard drive (formatting means you "delete" all the files, programs an your OS from your computer). when you format you hard drive you'll need to backup the files you don't want to lose. I recommend that you first run a cleaner program that cleans your registry, temp folder, etc. If your computer is still running slow (restart your computer after cleaning) you'll have to format and reinstall all your programs (even Windows/Mac! you'll need a Mac/Windows CD for this ). If your computer is STILL running slow you'll better buy a new, faster model because your computer can't be rescued anymore.If you're going to format please look up some information before you just click format! maybe you can ask some1 to help. One more tip: don't just download any cleaning program: it can badly harm your computer. ccleaner(piriform) is free software that works just fine also some anti virus programs and Windows vista got a cleaner program.
