Hi guys!! This is my first post because I've never really had many problems before with either of my computers. Well, I knew that I was going to get some bad luck soon, and it happened, so I came here!! Anyways, enough of the babbling on. Here's my problem: So, I've had a Power Mac G5 for quite some time now. I had previously thought that it was an early 2005 model, but according to it's serial number, it's actually an early 2004. In all the time I've had it, it's never had any problems, until now. About a month ago, I repartitioned the HDD so that I could dual boot Ubuntu. However, the installation went slightly awry, so I got rid of Ubuntu using the Leopard Installation Disk. Since then, the G5 has been plagued by random crashes, which I first attributed to EyeTV. During these crashes, the computer became completely unresponsive to anything apart from the off button. Then the crashes started when I wasn't running EyeTV, so I kept on having to force shut down. During this time, the G5 never once gave me an error report. However, when I started up the G5 this morning, I was met with a startup sound... And a blank screen. My monitor refused to acknowledge that there was a signal coming through, so I tried a different one. This monitor gave me the whole startup, but then crashed soon after giving me the desktop. However, I did briefly see an error report on the desktop saying' Mac OS X quit unexpectedly' before the screen went blank. Since then, I have tried a multitude of solutions, from resetting the PRAM and the PMU (twice), to reseating the graphics card. I have even tried booting in safe mode (also twice), and I ended up with a Kernel panic 'You need to restart your computer' screen and a safe mode desktop that soon froze and crashed. I know some people have had similar problems, but does anyone have the solution, or if not, another different possible solution that might work? Thanks for your time.
