Hi, I've got an 2008 20" iMac it's running OS X 10.8.2. Every few hours it crashes. I have completely restored the OS X. I've put new ram in, it's now 4gb.
I mainly use firefox, word and excel. It usualy crashs when I click a link or button somethings its when I move the mouse. I usually only have one app running at a time.
It seems to be completely random to when and what will make it crash.
When it crashes:
sometimes the screens goes black, with the backlight still on
sometimes the screens goes white
alot of the time it has vertical lines running down it
sometimes it freezing but i can still move the mouse.
If anyone has any ideas as to what I can do I would be very grateful.
Although you started with Leopard and upgraded, wonder if it might be better to make this into a Mountain Lion thread. It's probably agreeable to run both under the circumstances.
I'm wondering if the Hardware Test would work after such a significant upgrade.
