I think it's memory related, but I'm not sure. I tested my RAM that all went fine. And then I tested my HD which also turned out fine. Haven't crashed in 9 days so maybe it's solved, but my HD just feels slower, is louder, and just started beeping when I delete stuff. Anyway was wondering if anyone knows what all these errors mean and if it is the HD so I can be sure before I send it in to get a new one. Thanks!
