Computer My grandfather started acting up. What could be the problem?

My grandfather has a Dell XPS T500. It currently has Windows XP operating system and has about 8 years old. Yes, I know it's really old. Finally, he began acting up and it is taking too long to load simple web pages. The thing is that only a little way behind, was working. It's just plain old or there could be a bigger problem?

It could be many things, but I suggest do a scan with adaware spyware immediately this seems to be the problem for most PCs suddenly become slow lately. http://www.lavasoft.com/single/mirror_download.php?f=g2Obc772A
