I have my cousins macbook. I have about 24 hours to get it fixed before I go home 2 hours away. A little background. It's 2 years old. Has 2 gigs of ram. Not sure what speed the machine is. I think its 2.0ghz Core Duo. It was on 10.4.11. She told me it would just randomly pinwheel all the time and that she was having a lot of difficulty getting apps to launch properly. I figured ehh, it's been hangin around for 2 years, maybe it just needs a good format and fresh install of everything. So I put my Leopard Disk in. Did a format and install of the OS from the disk. Computer would not boot to the OS. Just sits at gray apple screen with the little spinning wheel thing like it's trying to boot. I decided well maybe something didn't work out well with the install, so i rebooted to the disk, went into disk util., manually formatted the HDD, then did another fresh install. Still no luck. I'm really stuck. Have no ideas and not many resources where I'm at, as I forgot my DriveGenius disk at home. I did bring my Tiger disk too so maybe ill try that, but i really wanted to put Leopard on her machine. Please give me some ideas! Thanks!
