[QUOTE="Jem, post: 298505, member: 19842"] You say you ran a hardware test? What hardware test did you use? The one on the supplied DVDs? The reason I ask is that if by "crash" you mean a Kernel Panic then I would strongly suspect faulty RAM despite the hardware test results. I had a similar issue when I upgraded my iMac memory (2 x 1GB) and had 1 faulty 1GB stick. The machine would work fine for a while then (I guess) whenever it started using the 2nd memory stick more intensively it would Kernel Panic and freeze. I found if I ran MacPAR on a LARGE (4GB) set of files this would cause the Kernel Panic as it's very memory intensive. The Apple diagnostics said the hardware was fine, however [URL="www.memtestosx.org/"]MemTest[/URL] showed that after a while one of the chips was starting to cause issues. If I ran it on a soak-test then it would fail perhaps on the 3rd set of checks although it had passed fine on the first 2 runs. It might be worth you running memtest (reboot and use the command line version as it's much more thorough) to try and isolate a bad memory stick before re-installing everything. [/QUOTE]
