unable to repair disk permissions and programs quit unexpectedly before opening

[Nomadic]

Think my mac is on the way out but would like to be sure before forking out a load of dosh. It has been playing up for a while. and at one point it got so bad that i had the HD replaced. since then very occasionally shuts down and I'm told i need to turn it off at the power button in various languages as the screen systematically gets darker. That's not a major problem (for me) but now i just tried to open Google chrome then safari then i photo and they quite unexpectedly before they have even opened. I opened disk utility and verified the drive and there was no reported problems. then i verified disk permissions and there were quite a few so i hit repair. I then get told that the repair failed.... hmmm. what does all this mean? I have backed up what I need on an external hard drive and am wondering if I delete the drive then reinstall maybe everything will be ok? any help and advice will be greatly appreciated. thank you.

G'day and welcome to the forums.

You are experiencing kernel panic attacks. May be hard drive failing but unable to help further as you do not supply model or operating system details. This applies for OS X.3 to OS X.8 and anywhere between.

Hi there,

Yes I thought maybe it was something like that but still don't understand why I'm unable to open programs.

I'ts an imac 11,3 with Mac OS X Version 10.6.8. intel Core i3 3.2 GHz

any ideas?

Boot from your Snow Leopard DVD, leave Installer and go to Utilities in the Menu Bar, Disk utility and run Repair Disk from there and see what is reported. Repair may fix the problem.

Gave the drive or the SL disc? Whichever you do have problems with no disc.
