Hi,

I am having some big trouble with my first Mac. I have a second 200gb HDD installed and it keeps shutting down and coming back on. Its a maxtor drive, so I know the drive is next to useless.

I have experienced programs crashing like quicktime and itunes, and sometimes on boot up OS freezes at the login prompt.

Could this be the cause of the maxtor? Or is it another problem ie the logic board?

Thanks in advance for all help!

Mj

Run the hardware test. There's a CD that came with your machine. Put that in and restart and hold down the "c" key. Follow instructions from there for full test.

Hi,

Thanks for the fast reply. I bought my machine on eBay, and it did not come with a hardware test CD.

Where can I get one of these?

Thanks,

Mj

Mj -

there is not a separate Diag disk... if you got the "install dvd's" with the computer, use dvd # 1 and boot holding the "d" key (not "c")

Good luck

This might be the problem. It could have been a lemon from the start, unloaded on the unsuspecting via eBay.

You need to show us some crashlogs from the crashed apps. And if you've experienced kernel panics (a screen telling you to restart the Mac in multiple languages), then you should post the contents of the panic logs as well.

OK so I dont have an install DVD just the CD version. I rebooted held in the D key and it just booted to my login prompt.

So, I rebooted again and went for a re-install and on the first attempt it crashed at about 17% of the base install.

I turned off the machine and opened the side, removed all hardware inlcuding the new 512 stick that I installed, this was DDR400 not 333 like the other 3 sticks.

I went back and did another re-install all completed fine and am now running again. I have encoded a movie and ran WoW and all seems to be ok. Before doing the above I did experience a few kernel panics. Could this be due to 'dodgy' RAM?
