Yep, I *know* so, from several machines I own myself and hundreds I have set up and sold. Check your configuration. Get a good utility/combination anti-virus program such as this one: http://download.cnet.com/Advanced-Syste ... 99324.html
Run that program, go to Toolbox, Optimize, Startup Manager. Disable all non-vital system programs/ tasks from starting automatically upon boot. Common culprits: Itunes, Skype, HP printers- notorious memory hogs- get a different printer, or try to configure the thing differently, Norton, AVG or other resident Antivirus programs- get rid of them, totally unnecessary, use this one instead, has a much smaller footprint, have used once a week, never had a virus for years: http://download.cnet.com/IObit-Malware- ... 67594.html
, Get rid of 90 % of Browser Toolbars and add-ons, remove Lenovo "clogware"- the only thing I really install on my laptops is Power Manager, PC Doctor, I.B.M. RecordNow, Bluetooth, audio, ultranav, video, ethernet and Wifi drivers and let Windows manage WIFI !, Yahoo Messenger- this type of program wants to run automatically upon startup so it can pop up in your face so you will use it more often, but it has a setting where you can configure it to only run when you click it on, also get rid of Realplayer- totally unnecessary trash- many other non-invasive video playing, video downloading programs out there that don't hog memory and resources, etc.
These are just a few off the top of my head, but there are many more such programs which people download and install and begin to slow down their system. All I know is that all my laptops boot up and shut down in a jiffy and I don't plan on investing in SSD technology anytime soon as SATA hard drive technology works just fine and is plenty fast for me. I do a lot of MS Word 2007 processing, video and audio editing, video downloading/uploading/archiving, have 15 Firefox windows constantly open (think Internet Explorer is an amateurish joke, tried Google Chrome once- another memory hog I will never use again), stream online videos and play music on my laptop constantly, work on my Christian website, print documents on a laser printer constantly, as well as a bunch of other things and 2GB on several Windows 7 Pro T60's/R60's I have or 3GB memory on my Windows Ultimate T61 and X60 tablet is plenty.
I am constantly amazed when I use some of my friends' laptops how clumsily and inefficiently they are set up. THERE IS AN ART TO SETTING UP A LAPTOP! I have laptops running for years now as smoothly and speedily if not more smoothly than when I first set them up.
People just keep installing and downloading stuff and never bother to do a good registry defrag/ hard drive defrag/ system tune up/ optimization/ virus check/ or CONTROL WHICH PROGRAMS RUN AUTOMATICALLY AT STARTUP! They never bother checking all programs installed to see if something they have downloaded might have installed components they never asked for. Sometimes they clog up their system so badly/ mess up the registry/ have bits and pieces of programs floating around/ that trying to uninstall/ fix up such a mess is futile and it's best to backup up all their data, make a list of NECESSARY programs to reinstall, start all over with a fresh format/ fresh installation and this time do it right.
