Hi guys, I have a late 2007 MacBook Intel Core 2 Duo. Upgraded the ram to 4GB and upgraded the HD to 320GB, running Leopard 10.5.7. I was having problems for the past week now of it being slow and hangs. This afternoon, it was acting slow again and was hanging, so I tried Repair Disk Permissions and Verify Disk Permissions. The permissions were completed and the results seem fine. It didn't give out any errors or anything like that. I decided to restart it just so it can refresh itself, but it was slow and sort of hanged upon loading the desktop and everything, so I forced shut down holding the power button and when I pressed it again to open it, it gave me this error icon instead of the apple logo. Sorry, I can't upload an image now cause I'm only using my phone and it's pretty difficult. I'll post them later when I get a hold of a computer. In the meantime, I hope you can help me out here. Thanks. UPDATE: Here's how my screen looks like when I open my MacBook: You guys think its a Hard Drive problem? will I still be able to retrieve my files?
