First off I would like to say that I did try searching (I know it's hard to believe that coming from a member with no posts) but its difficult to search for my problem because I don't really know how to describe it in keywords and get results. This probably isn't the right section but once again I'm not really sure how to describe my problem. Here is the story. I primarily use Windows 7 on my computer through Bootcamp. (I also have Linux Mint 10 on my computer, don't think either of these are part of the problem but I thought I should let you know) I have had both of these installed for a while, and switch between them with no problems until yesterday. I booted into Snow Leopard (10.6.5) to update my iPhone firmware. The first time I booted into it, it would only load my wallpaper. I rebooted and this time I got my dock and task bar, but was unable to do anything other than move the mouse. I got right down to business and started the formatting process. I put the Snow Leopard disk in, but that somehow kicked my computer into action. I was able to use it, but it was very slow. So I uninstalled my themes thinking this was the problem. the themes required me to log off so I did that but it froze from there. Then I rebooted and tried the Snow Leopard disk trick again. It didn't work, but my computer was responsive after a few minutes (I don't think the disk had anything to do with it becoming responsive either, just think my computer was being slow) After that I ran Onyx thinking it would fix all of my problems. It didn't. From here I started the formatting process. The first time around I really messed up (it was 2am and I had only gotten three hours of sleep, give me a break) instead of doing a clean install I accidentally did an upgrade. I woke up to find my computer still being it's slow self. I then spent the entire day today, formatting, reinstalling multiple times. It was slow even when I didn't restore from a backup. No matter what I would do my Mac would be unbearably slow (it wouldn't even load the welcome video, just show a blue screen while playing the music) Here is the part that baffles me. My Windows partition still works (haven't tried my Linux Partition but I assume it also works) I don't think that my multiple partitions are the problem because I have had them all working since about July (I even upgraded Linux 9 to 10 two months ago without a problem) I don't think I'm technologically inept but this is beyond me. My next step will be to replace my hard drive, but I have low hopes for that doing much, unless bad sectors are my problem (dunno if that could even be a culprit) Hopefully I can fix this problem without sending it into Apple. I do have Apple Care but I doubt that warranty actually does anything, they'll just blame it on me so I have to spend another $1,000 to fix it or buy a new computer. Lets just say it won't be another Mac. I have the late 2008 aluminum MacBook (non pro) intel core 2 duo Thank you for reading.
