Hello, I'm trying to fix a 12" 1.33 Powerbook. It currently has Leopard installed on it. Here's the scenario: It's my girlfriend's computer, she's been having problems as of late since she's installed Leopard. She only has 512 RAM and I've been pushing her to upgrade to a gig chip but she hasn't gotten to it yet. The main reason we put Leopard on her Powerbook was for Time Machine. She got an external hard drive and the during the first backup, her Powerbook went to sleep which caused it to hang and not turn back on in the morning. Naturally, having to force restart and what not, I believe the Time Machine backup became corrupted. Other than that, her computer worked fine the rest of the week. Now fast forward to yesterday. She ran Time Machine the night before, and saw it complete, then turned off her computer. Yesterday in the morning, she turns on her computer and it doesn't get past the Apple logo startup screen. I reset PRAM, etc it didn't work. I booted off the Leopard disk and ran disk utility, did a repair disk on her main drive. It ended up allowing her to boot into OS X (albeit a much longer boot process than usual). Eventually I was testing out her OS to make sure everything was stable and she got a kernel panic (Restart black screen message). I restarted, now it crashes almost every time we load. So I go back to load the Leopard disk and tried to restore from Time Machine. It does a kernel panic while running the restore program. I unplugged her external drive (no other peripherals) and then tried to just boot off the disk to run disk utility to at least get her computer running long enough so I can recover her important documents. Now every time I run disk util (off the Leopard CD) it kernel panics / crashes. Every time. I'm starting to get mildly frustrated here and could REALLY use some ideas. Pleeeeease Is there any possible way to reinstall Tiger or Leopard on her computer? Is it her hard drive? Why is it crashing all of a sudden over the past few days? Software wise, etc she hasn't changed anything. She only runs Safari, and Word. No jolts or anything unusual to the computer, hasn't been dropped, we haven't installed any new RAM, still the same Powerbook she's had for years. I'd at least like it to last long enough to Christmas so I can get her a new Macbook.
