I’m curious why you don’t upgrade to service pack 2 or even 3? If you own a copy of windows it’s free. If you stole a copy of windows, steal a new copy. If I recall Corectly, SP2 was primarily put forth as a security wrap up to prevent things like worms and trojans. If you have an old operating system, do you have an old AV program also? You might be actually having these problems because of your refusal to upgrade your software. And BTW minimum requirements for lots of software are just guidelines, and stuff often runs on lesser machines at an acceptable level. (I wouldn’t be afraid of Chrome or SP2)

Edit: Just wanted to add a link in case you have never heard of this site:

(I believe they update windows the second Tuesday of every month)
