Before investing in extra hardware you should run the spyware/adware and virus detection software. Also run scandisk and defrag on your harddrive. Lastly you might also try going to Start --> Run --> type "msconfig" enter... DO NOT touch the items uder the first couple tabs, just go to startup and turn off all the crap that is mostly unnecessary to begin with. If you do not know what something is, just look at the path it is run from. If it says C:WINDOWS.... then leave it alone, if it's some crap like C:PROGRAM FILESGOOGLE... then turn that kind of crap off, it serves no purpose other than self imposed advertising. Msconfig will make a huge difference sometimes, JUST REMEMBER only alter items under the startup tab unless you really know what you're doing. Hope this helps!
