|When you say the computer is taking a long time to load, what do you mean by load...|
Do you mean it takes a long time to run a certain program, in this case it would be worth checking the program and making sure it is up-to-date, and that it is configured correctly.
If you meant that the computer takes a long time to turn on, then you might want to try checking what programs are running on boot up (look in the bottom right-hand corner) and checking which one's you don't need
Failing that, go into ADD/REMOVE programs in control panel, and uninstall all programs you do not want/need, and then perform a disk defrag
Hope these instructions help :P
