Hmm.. she could have a lot of programs or adware loading whenever the computer boots up. Try this:
Goto Start >> Run >> Type in "msconfig" (no quotes), hit Enter >> Click on the "Startup" tab
I personally weould click "Disable All" just because I know what should be running on my computer and what shouldn't. But if you don't know what it is, chances are you don't need it. Don't worry, removing any of those objects won't keep your computer from working. Just read through them because some of them would be your McAfee or Norton or whatever you may use. After you're done, "Apply" then "OK" and restart your computer.
Something else that also helps your computer run a bit faster is a program called CCleaner. Just google it, works wonders. It get's rid of all your cache, cookies, temps, etc. If you don't already, I recommend running Ad-Aware and SpyBot. Those are definite musts.
Let me know how it turns out.
