[QUOTE="skay2, post: 1802698, member: 400781"] Hi all, I m given a late 2009 iMac 10.1 EMC2308 which has a little problem. I took the iMac to an authorised repair shop and was told its already a vintage. It still look like brand new to me though. The main issue is the iMac constantly restarts with this message : "Your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up." followed by another alert message after the restart : "You shut down your computer because of a problem." I then tried a few things : (1) Disk Utility - repair disk. Same problem comes back after the repair and on one occasion it says Disk Utility can't repair this disk? I am about to do a disk replacement! (2) Memory Test - The previous owner had 2 extra SODIMM Crucial Memory (4GB DDR3-1066) added 2 years ago. I ran memtest and got FAILURE reports. I removed the two Crucial Memory and ran the original memory with OK report. I then remove the original memory and inserted the Crucial Memory, it went FAILURE again. (3) I was told to run a hardware test on the iMac first before any further action on Disk and/or Memory replacement. I have the original iMac Applications Install DVD that came with the Mac. I tried to launch Apple Hardware Test (version 3A190 as stated on the DVD) and restart while holding down the D key (as advised on the DVD) with the disc in the drive. However, the drive kept ejecting the DVD by itself and the system went into normal boot every time. I just cannot get AHT to run. I am quite lost as to what action to take next. So is it HDD or Memory that I need or both? I am brave enough and don't mind to try opening the iMac and replace the HDD or even SSD, and I am prepared to buy new Memory. sk [/QUOTE]
