Are you having computer troubles?  Is that computer slowing down?  One thing to check your system for is a Computer Virus.  For the last couple of years I have used AVG Free Edition Anti-Virus Software and like it alot better than Norton or McAfee, the main reason is because Norton and McAfee seem to try and take over your System and then it gets slower and slower, they do a good job, but they tend to monitor everything.  So I started looking for something that did one thing, Virus Protection, and AVG is perfect for this, it is truly worth the $33, but if you want it free, it is available at this time, not sure how long they will keep it free, but get it while it lasts.
