I have a new computer ( dell Pentium D processors 2.8 ghz) My hard drive is a sata drive. Wich linux will be better for to install on my computer.

I think anyone would be ok, but I prefer to SlackWare

If your looking for one thats easy to use and has good hardware support (out of the box) i've had good luck with ubuntu and mandriva (If you install mandriva, quickly uninstall KAT, it's very buggy)

For beginners, I recommend starting with ANY of the free distros---eg Ubuntu, Fedora, OpenSUSE. Chances a quite high you will try several before settling down.
Ubuntu is a very good place to start---lots of documentation and fora available.

I think Ubuntu would probably be a good choice.

you may want to wait for opensuse 10.1 to come out...but I would say opensuse is a good place

Of all the distros I've tried, the one I recommend is Gentoo. Great package mangement.

I wouldn't recommend fedora (unless they have released a fedora 5). I found it bloated and not as polished as slackware or ubuntu.

For a first time linux user I recommend kubuntu simply for the ease of the debian type systems. Its ubuntu with the KDE interface vs. the Gnome ubuntu uses.

Just my opinion:
I wouldn't recommend slackware for a first time user. Slackers even brag about how they need to truly understand Linux to be able to configure it. Plus PAM support has become a Linux standard with both RPM and Debian based distros but isn't used by slack. However, slackware may be the distro of choice if speed is the determining factor.

Try one of, Ubuntu, Fedora, OpenSUSE, Gentoo, Mandriva. Fedora, OpenSuSE, and Mandriva are all forks of an earlier Red Hat Linux, (Fedora is Red Hat's non enterprise versions after Red Hat 9), so they use Red Hat's RPM packaging system. Gentoo is a debian derivative so it uses DEB packages.

I've never used Ubuntoo, but I would recommend Mandriva or SuSE or OpenSUSE.

No we don't, that's not true

try live cd's to choose one
that is what i did and found the best one for me

I've gotta agree with the folks above with ubuntu.. I'm not a linux beginner, and I love ubuntu. It's easy, slick, quick and installs with one cd! You can't get much better than this....

AlienDog, I'm sorry if I ruffled your feathers. I have seen many messages on this site making that boast (and when I read it, I think of LFS), but I don't want to make the mistake of characterizing all Slackware users so. If I could use an analogy, Slackware is like a high performance race car. Some of the other distros are more like Mercedes or Rolls Royces. A formula race car can go faster then a luxury car, but takes more skill to handle. I still hold the opinion that not supporting PAM by default (although a user may add and set it up himself ) is a major shortcoming.

Veering further off-topic, he said: I did not see ruffled feathers--only tongue in cheek. Or was that tongue in feathers and ruffled cheek....Oh dear!!
All note: OP long gone--graybeards left muttering to themselves.
