Hi guys - I have a late 08 15in MBP that up until about 2 weeks ago ran great... THEN I started to notice a drastic change in performance. So... I ran Onyx and it told me I had a problem with the Volume Opened Disk Utility and ran Verify and Repair - both ran with some exceptions at the bottom that I didn't understand I ran Tech Tool Deluxe and it told me there was a problem with Volume Structure but gave me no option to repair I've also been having issues with the screen freezing and pixels showing up. Is there a correlation? Any and ALL help is appreciated since I'm pretty clueless about these kind of things... Thank you!
