Over the last week I've gotten 3 kernal panics. After I shutdown I cannot start it up for 5-10 minutes. This happens while I'm playing games such as Wow or CoD2. The case has also been getting much hotter then normal so I'm starting to think it's a heat / fan issue. I hope nothing major is wrong I've already had to have Apple have to repair is once . Any advice for me about this issue? Thanks.
