Total lockups

[Pagemakers]

I've got a Mac Pro Early 2009 running ML.

Everything has been fine until a few days ago, whereupon the entire system will lockup with the spinning ball of death after 10-15 minutes.

No software was installed or modifications made prior to this happening.

Things I've tried so far:

1. Reboot: After rebooting it still happens even with nothing running.
2. Re-installed ML
3. Swapped the memory with another identical machine

Any ideas?

HDD is the first suspect when it comes to BBOD + freezes.

I'm running SSD

I meant boot drive, regardless whether it's spinning or not
SSDs can die as well. Try another drive. Check what's logged in system.log in console.

What type of things should I look for in system log?

Any errors just before lock-up, especially I/O errors.

Thanks.

I'll check as soon as the next lockup happens.
