Kernel Panic Error after last MAC OSX update

Question

Hi all,
My first post here.
Last week, after install the last update of MAC OSX on my intel IMac (last of 2009), when the computer was restarting, a kernel error screen appears...
I've launched the safe mode, and the computer starts fine and I've execute the disk utility to repair HDD and rights. I've done the same initializing from the installation DVD, but the kernel error appears again...
I leave only the usb apple keyboard plugged, and I don't understand why this error still happening, and of course why it occurs after a MAC OSX standard update (no new hardware or software installed in the las month).
I'm little desperate with this issue
kernel error.
Many thanks in advance!
Best regards
Hugo

Hi Hugo, & a warm welcome to the forums!
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport in 10.4 & below, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
It does look like the com.metakine.handsoff.driver, whatever that's about.
