Last week, I got my first ever kernel panic. Screen said, "you must
shut down ... " etc. I ran everything I knew how to for diagnostics -
which was only the Utilities and then Onyx to clear all caches and
tidy up stuff. It ran smoothly after this so I thought it was okay
again.
Today it crashed with same kernel panic. But - when I forced reboot,
it would only show the apple icon and spinning thing - then slowly it
went to a blue screen. Blue screen flickered, but did nothing to
finish booting.
The Tiger disk I have isn't for the eMac specifically. So I took my
eMac original disks out (with 10.3-something.) and ran the hardware
test.
It came up with a memory error: Erorr code 2MEM/104/4:DIMM1/J1
I read some obscur post somewhere that said it is possible that when
upgrading OS the old RAM will be obsolete. I don't know which OS's it
was talking about though. Could this be my problem?
I only know enough to be dangerous about diagnostics - so your advice
would be very appreciated. If it is the RAM, is it both chips? If I
could limp along with only one for a while, that would be workable -
no cash for replacement or repair. Hoping you can help me learn what I
need to get the eMac running again.
Try removing one stick of RAM if you can and see how it behaves, then
replace that stick and remove the other stick and again see how it
behaves. If it works with one and not the other you've diagnosed the
problem, if it doesn't work with either stick of RAM then either both
are bad or not up to spec, or you have a different problem.
