Unfortunately, simply stating your computer is slow makes little sense. There are thousands if not millions of reasons why a computer is slow.
The best solution, if you don't have the ability to diagnose the problem, is to ask a adjacent computer technician to help you. Forum systems are asynchronous, therefore very unsuitable for complicated diagnostic tasks.

At least you need tell us what operating site your dad is using: Windows, Linux, Mac OS X, NetBSD/OpenBSD/FreeBSD, BeOS/Haiku, OpenVMS, or MS-DOS 1.0?
If you are on a operating system that's way too popular and there are numerous malware and viruses targeted at it -- I mean Microsoft Windows -- check for viruses firstly. And check startup applications and running processes with Task Manager, msconfig, and Hijackthis or some similar tools. Make sure there's not a process that eats 50% of your CPU resources.
Well, when is the computer slow? When it's booting, or when it's running? Is an application specifically slow, or just any applications are?
Restoring a system backup might be helpful, provided that you have one.

And reinstalling the operating system is the typically considered as the ugliest solution -- However it might be useful if you really don't know how to fix it.
