What I was initially trying to understand clearly with my earlier questions was if there was a connection between upgrading to Yosemite and the crashing problem. Your first post in the thread mentioned upgrading to Yosemite, slowness, and the crashing. So initially it was unclear if there was any connection between the Yosemite OS upgrade and the crashing.
After some questions to clarify things…it sounds like you've been using Yosemite for about 6 months. Since you've been using Yosemite for about 6 months…I don't think that there's a link between the Yosemite OS upgrade & the crashing.
So to summarize:
1. There probably isn't a link between the Yosemite upgrade and the crashing. The computer has been running Yosemite for about 6 months…and the crashing started recently.
2. There probably is a link between the OS upgrade from OS 10.6 (Snow Leopard) and OS 10.10 (Yosemite). Simply because typically...the newer the OS version the more demand on the computer. One way to help with this is to upgrade the ram on the computer. 2gig of ram (the amount of ram you said you thought this computer has) just isn't enough. You could either upgrade to 4gig or 6gig of ram with this 2007 iMac (if we have the correct model & year identified). And the ram upgrade should help with the slowness.
3. The crashing. This is the big problem area. Usually this crashing (kernel panics) are hardware related…but they can be software related as well. If you've been running Yosemite for about 6 months…I don't think that Yosemite is causing the crashing.
- So if it's a software problem…the problem is something other than the OS. Did you install any new software (apps) recently (since the crashing began)?
- Do you have any external devices connected to the computer?
- If we eliminate software problems & external devices connected to the computer…then the computer may have a hardware problem.
- Hardware problems most commonly are related to…bad ram, a bad hard drive, or a bad logic board. Bad ram & a bad hard drive can be replaced for a reasonable cost. But if a bad logic board is the problem…then replacing the logic board would not be worth it on a computer this old (~8 years).
Let me know your thoughts…and answers to the questions.
