welcome to linux ddotyp.
It might have been something you did or maybe not,just a sour update.
I encourage you to try multiple distros since you uninstalled anyway.
I'd stick with the major distros at first.They have gotten really good lately.Get your >iso's from here :http://distrowatch.com/
My distro's dujor are the new suse,mandriva,and centos.
Live cd's are always cool too.Knoppix,Dsl,mepis,slax.
Puppy live has a utility you can burn you own custom live cd.Very cool stuff.
