clock fast and iso issues

[n0cud06]

Hello,

I've installed aitkos 5i and everything worked while 10.5.5 then I ran "software updates" to 10.5.6 and now I got some issues

1) my clock is fast a full minute every 10 - TRIED - upgraded boot to chameleon 2.0, repair permissions - nothing helped

2) Some of my dmg and iso images won't mount it says "no mountable file systems" (ilife09.dmg, firefox.dmg all worked fine) - My dvd movies won't mount either.

Any idea?

here is my extension folder: http://69.108.218.45/wip

INTEL BLKDP35PM CORE 2 QUAD/ INTEL P35/FSB/1333
5GB DDR2 RAM
