I'm thinking about upgrading my parents old pc. It is a HP xt858 from 2001. It has a 1 Ghz Pentium 3, 192 megabytes of PC-133 SDRAM, a 60 gigabyte hard drive, 8x cd burner, and Windows Millennium Edition. It runs terribly slow right now, mainly because in the 6+ years they have owned it they have never reinstalled the OS. I do virus and spyware scans on it and other than some cookies it always comes up clean, they don't visit bad sites and they do have firewall software installed. I know reinstalling the OS would help a ton, but I don't want to install ME on there, since it was junk to begin with and now that it is unsupported, well its not worthwhile.
Here are some of the upgrades I am thinking of. Would this be worthwhile? Keep in mind all my parents use it for is web browsing, Word and Excel, and Solitaire. They don't do any gaming or video or music encoding or anything else that is very processor intensive.
2 sticks of this memory
This hard drive
A copy of Windows XP
and up to date internet security software
The total upgrade is about $235. Anyhting else I'm missing? Or any better suggestions are welcome.
