Okay, I'm having a serious issue. Any time I boot my computer in OS X (Leopard, 10.5.7), I get a kernel panic - I do not even get past the gray screen with the Apple logo. Similarly, if I try to boot from my Leopard DVD - I STILL get the kernel panic. I cannot even reformat my computer. But before you say I must have bad memory, etc., I have Vista installed using Boot Camp - which works just fine. Only OS X has issues. But since I cannot even boot from the DVD... I'm really desparate here... I have no idea what to do. How can I get my computer running again? If it's of any relevance, I have: - Early 2008 mac pro - The drive using OS X is separate from the Vista (two HD's); however, should this really matter considering the fact I cannot boot from the DVD? Okay well I'm open to any advice, I need to get my computer working as soon as humanely possible (obviously) so I'd grandly appreciate suggestions. Thanks. Anyone?
