I installed 10.5.5 on my desktop. It has an AMD proc and a Biostar mobo. It runs fine for the most part but occasionally OSX crashes and says I have to restart my computer. Is this because of the processor? and is there any way to correct it? Also, I'm dual booting Vista and OSX and if I want to switch to OSX I have to complete power down and power back up to boot into it because the ethernet won't work otherwise. Can this be corrected?

Thanks

hey,
have a look here to see if there are any problems with your mobo tht cold be fixed. as for switching os - yes you will have to power off and on to use the other system but if you don't mind reduced memory then you could use bootcamp on VMWare (Fusion for mac) to switch easily between them.
