F13 crashes on half of boots

[Max Gene]

Hello everyone. I switched over to Fedora a little while ago, maybe a month or two, towards the end of when 12 was out. 12 ran just fine, but around when I upgraded to 13 I started experiencing issues. I first upgraded by switching repositories and installing via yum, which seemed to run fine for awhile. However, came to the point where about every other boot (a little more often, actually), the system would crash at the login screen, not allowing me to login. Ctrl-Alt-Backspace or other rescue keys don't work- in fact, if the mouse is still working, they freeze the pointer as well.

Finally I decided to get the 13 DVD and re-install. Downloaded, media checked out, ran the install... and I'm still having the same issues. I know I should be providing more info here, but I'm not sure what log files to look for and post here. A few notes of relevance are that I've tried changing the ACPI settings in my BIOS to be as compatible as possible, and also tried booting using noacpi, which doesn't seem to be fixing it- I also have Nouveau installed.

So, what should I do? Anything I need to provide to help troubleshoot, I'll gladly do.

My system started to boot, using compiz fusion, and would hang just before the login.
Not knowing what to do, I used my windows machine to try and find a solution that is written in plain english.
It seems that if you don't know anything about these linux os's your screwed when it comes getting help.
I looked at the OpenSuse forum - they had a thread about explaining the os to new users - most of the posts were insulting and derogatory. Got the feeling that if your not in the click, your not getting in.
The Fedora Forum, thankfully has not been that way.
Anyway to my question,
Is there any help written in plain english, or translation from computer speek that would help start us out?
Thanks

Can you do Ctrl-Alt-F2 and login as root to a virtual console? If yes, you should be able to log at the following log files:
1) /var/log/messages
2) /var/log/Xorg.0.log
3) /var/log/boot.log

I made copies and attached them, if that'll work.
