GUI Freeze after sleep mode

Hi,

This is my first post because here after searching your and other forums.

I've got 2007 aluminium iMac that freezes up after sleepmode and normal use. The spinning beachball appears and the GUI get's stuck. Only the cursor moves. Only a hard reboot get's the machine online again.

I tried the following:

  • fresh system software
  • checked all firmware updates
  • reinstalled the original ram modules
  • installed a other hdd
  • ran several tools like TechTool deluxe to pinpoint the problem

None of the above helped. I extracted code the following from the Console App. This code is generated after the system freezes up.

Could it be my video card is the cause of this?

''Run Applications->Utilities->Disk Utility->DFA-repair drive'' on your disk drive. Sounds like your HD is failing. Be sure to back up any important data. Also try resetting the PRAM. If this works you could need a new backup battery for the Logic Board.
