Apple hardware test freezes
My iMac has been having frequent freeze-ups - i get the little black box that says i have to restart the computer.Tends to be memory intensive tasks - for example i can copy from one disk to another but can't clone.
I have been trying to use the hardware test from my original install disks. The only thing connected is the apple keyboard and apple mouse. Ram sticks are from crucial and i have had them in there since i bought the computer ( bought it when they discontinued the 17" model). Hardware test freezes:
1.first time while trying to do its initial probe
2. second time at the language selection window
3. third time 1min 30sec into the extended check
4 fourth time at 22sec into the regular check.
if i shutdown with power button, unplug and wait maybe 15 minutes, the computer will boot into the usual desktop but sooner or later i get another freezeup. I am concerned that the operating system will get borked from the frequent powering off with the power button.
do these symptoms suggest any particular problem? could a failing battery cause this?
