Can someone tell my why every time I try to use 7z it freezes my system? I can't move my mouse, I can't type, I can't kill my xsession. I then restart my system and everything returns to normal. When I try to use 7z my system again freezes.
What do you mean by "crashes your system"? How are you using it?
7z crashing your system, if you mean a catastrophic failure of some sort, is very unusual and may point to memory errors or some other hardware problem. I remember you complaining about random utilities segfaulting before, did you get that resolved?
Sorry wrong word choice. It freezes my system. I can't move my mouse, I can't type, I can't kill my xsession. I then restart my system and everything returns to normal. When I try to use 7z my system again freezes.
It was ps that was having a segmentation fault. It lasted for about 3 days. I don't understand what caused it or how it got fixed. I just used top instead. That took care of the job for me. I do a bit of simple programming so it was quite surprising to see a segmentation fault when I was not programming.
I guess I should go back to Linux Mint or Ubuntu. I never had this many problems with those two os's. There was good documentation about everything your heart could desire. I didn't have to ask a ton of questions like I have to do now. I could just use google. I have not been able to find good documentation of Fedora. Two examples are dual monitors and startup scripts. I know I can't be the first person to want to use dual monitors and startup scripts with Fedora.
That's a longwinded way of saying 'no'. 
ps wouldn't be crashing on a properly functioning system, period; and if you didn't find the problem, it's still there.
It might have been just one corrupted file if it was just ps. But if 7z is not merely crashing, but freezing your entire system? You've (still) got memory errors, or a hardware problem. Kernel bug isn't impossible but hardware seems more likely. At the very least run memtest86 for a while.
As I said in your other thread, this is extremely unusual and usually points to a hardware problem. You can hardly blame the OS for failing hardware.
You're going to have a hard time guilting us over your difficulty when you seemed to pay so little attention to it.
ps should never segfault. Period. IS this an ancient version? 9 or something earlier?
Did you load up a bunch of system utilities from the HPUX Porting Centre?
Is there a version of this in one of the fedora repositories? Is there a difference between these 2 sites with memtest?
Memtest86 - Download Page
Memtest86+ - Advanced Memory Diagnostic Tool
Sorry that wasn't my intention. How do you recommend I pay more attention to my system then?
I assume you were asking my fedora version? ps isn't even close to version 9. I am using fedora 15.
ps --version
procps version 3.2.8
Since I don't know what HPUX Porting Centre I am going to assume I don't have it.
This is all of the software I have attempted to install on my system. I always use command line so I know this is it. A few of them I know don't exist I was just checking if they exist.

I would suggest you use memtest86+ (better from my point of view) and use a bootable ISO image, to remove any issues regarding your kernel.
You state that you are using Fedora 15.
Where did you get 7z from? It is not available in the Fedora 15 repositories.
memtest86 is usually used as a standalone tool, because a machine with faulty memory usually can't run an operating system reliably. It comes on many rescue CD's and the like, and Gentoo's "install-x86-minimal" livecd's. Just type in 'memtest86' at the Gentoo CD's boot prompt and hit enter. After that point memtest86 is standalone (doesn't even need the CD).
I just checked a live cd of Fedora 15 and it has 7z. Would that be why its not in the repositories that you checked?
Is this what you are talking about?

I am wrong. It is in the Fedora repositories. See https://admin.fedoraproject.org/pkgdb/acls/name/p7zip?\_csrf_token=0ae715db6cca435716f63e6939d275cc62982ed2\#f15
