[QUOTE="barnola, post: 1353098, member: 224355"] Apologies chscaq for not replying sooner. I'm in England 6 hours ahead of Texas (8 hours CA Dennis) and my last message was at 1:30 AM. Ran MemTest Last login: Tue Jan 10 11:24:18 on ttys000 richard-barness-imac:~ barn$ memtest all 9 Memtest version 4.22 (64-bit) Copyright (C) 2004 Charles Cazabon Copyright (C) 2004-2008 Tony Scaminaci (Macintosh port) Licensed under the GNU General Public License version 2 only Mac OS X 10.5.8 (9L31a) running in multiuser mode Memory Page Size: 4096 System has 2 Intel core(s) with SSE Requested memory: 2497MB (2618548224 bytes) Available memory: 2497MB (2618548224 bytes) Allocated memory: 2497MB (2618548224 bytes) at local address 0x0000000101000000 Attempting memory lock... locked successfully Partitioning memory into 2 comparison buffers...

Execution time: 1084 seconds. Many thanks for pointing me in this direction. Can I fix this myself? Could the memory chips just need re-seating? I've put memory chips in my Quadra years ago but doesn't the imac need an Apple tech? [/QUOTE]
