Hi all,

I have a 20" Intel Imac and I recently upgraded the hard drive (250gb to 750gb) and ram (2 X 1GB modules). I got the parts installed by my local Apple centre and installed the OS myself (leopard)

Since the install finished the system hangs or freezes every 30 seconds or so for about 1 minute. It does this 3 or 4 times and then stops responding until rebooted.

I've put back in the original RAM and it made no difference. I then installed XP (i'm a windows admin and I wanted to run tests on the drive) and the system worked fine without problems. So I put back on leopard and it happened again.

I'm installing Tiger now as it came with the system first day but I'm getting really frustrated. Has anyone got any suggestions.

i found this article which suggests its an issue with the drive ( I have the 750GB instead of the 1TB version).

I tried forcing the drive to 1.5gbps as mentioned in the article but it made no change.

I would take the machine back to your local Apple store and let them sort out the problem. If it's the hard drive as the article suggests, tell them to replace it with a different model.

Freeze ups are very hard to trouble shoot as they are usually intermittent and difficult to pinpoint. In your situation, however, it almost has to be something to do with the upgrade done by the Apple store.

Regards.
