Computer freezes after I enter my user and pass when login to gnome

I am running FC12 64bit on my desktop and the problem is that after I enter my credentials at graphicall login screen (Gnome) the computer hungs i cannot moove the mouse, CTRL+ALT+DEL won't work the Caps and Scroll lock on my keboard are blinking. Nothing responds. I am absolutelly cluless. Untill yesterday i was using FC12 i686 and never had this problem, but i got 4GB ram so in order to get those fully i installed the 64bit version. On clean install of the 64bit ver everything went fine, but i updated the system and followed theese instroctions [LINK][/LINK] and that's all.

Before i atempt to login i can ssh to the machine.

I would appreciate youre help because I don't like the reinstall sollution, with youre help i might just learn something new!!

THX in advanc!!!

It sounds like you're having a kernel panic, from the console try to update the kernel and reboot... or revert to a previous kernel and see if that resolves the issue. Do your logs say anything?

I cannot

yum update
because I get

Segmentation fault (core dumped)
if i revert to the previous kernell the problem remains, and about the logs can u please be more speciffic?

maybe try rpm with options to go to previous kernel* ?

I have booted with previous kernel and i still have the same problem

How about a manual update of the kernel via rpm? try dmesg and see what it reports for one, then check your messages file for any information that seems 'odd' around time of boot.

Hi, I've just figured uot what was my problem...the extra 2GB of RAM that I've added recently.I ran a memtest and the answer hit me in the face; the dimm was broken.
THX everybody for support.
