Cannot login as user after hard crash - gThumb

i was downloading a few hundred photos using gThumb and watching TV. i looked back over to the pc during transfer and the screen was blank. No keystrokes had any result. i manually restarted and upon reboot, i was required to fsck both hda1 and hdb1 with many errors on both. When the pc finally booted, it displayed the login screen as normal, but upon entering the password i received an error saying i did not have access to my home directory and settings. When i clicked ok for that screen it only showed the blank tan background and no icons or bars ever appeared. i am able to login as root with no problems. Then i chmod my user home dir to 644 and now it begins to login after entering password but stops with the tan background and the following error appears and i cannot proceed to login:

=======================
i logged in as root and created another profile. Logged into that profile and tried to transfer more photos from my Nikon D200, a few seconds and it crashed that profile and had hard drive problems on restart. i am now working on a third profile, no access to 2nd profile and limited access to first. i am now unable to use sudo also.
