Hi guys,

I'm having an issue with my C2D blackbook that seems to be getting worse over time. Probably the first symptom, assuming they're related, is that flash video performance started to get really bad. I'm not talking about the high CPU usage, fans going nuts but video still playing smoothly that seems common across all Macs due to the fact Flash is a complete dog - but flash video would start skipping, the audio would degrade (sometimes switching the sound output to headphones then back to speakers would fix this, no idea why) and often beachballs. It's at the point where watching something in streaming video, or even just YouTube clips, is unbearable - I have installed Click2Flash, so that helps with YouTube, but even though Flash is bad I don't think it's meant to be THIS bad.

So I tried a clean install, thinking that maybe, in the upgrade from Leopard to Snow Leopard, that Flash somehow got a bit f'ed up. Even with a completely clean system, with nothing restored at all from backups, it didn't take long for the issue to reappear. It's particularly noticeable when streaming live video, such as live.twit.tv or Cnet's live streams.

I've also tried upgrading to the new beta version of Flash but that hasn't seemed to have fixed the problem.

Now, when I leave my computer on and walk away from it, I often comeback to find a Kernel Panic. It's happened 3-4 times in the past week or so, and is starting to really worry me. The computer is still under Applecare, but I'm starting to thing something may be up in the hardware.

Here's an example of some of the panics (think I've pasted the important bits, let me know if not):

Any ideas what's going on or what course of action I should take to determine if there's any hardware issues? Thanks.

If you've paid for Applecare, why not use your warranty and ask the experts? Can't you email the above to a help desk or something? Whether its hardware or software related, you should be able to get some professional help rather than stressing and worrying, and possibly getting conflicting advice from (the admittedly normally 100% spot-on) mactalkers.

Good point, just didn't want to go to the trouble of trekking into the apple store if there was an easy solution I was missing.

Fair enough though, will shoot off an email or give Apple a call.
