Today my MacBook giving me a very big problem. After I update the OS to 10.4.8, I restart it (it's normal, right?) then it won't boot into dekstop. The grey waiting circle below the apple logo (you all knew what is it,right?) keep on spinning and although I left it for 3 hours it still same. Then I try to boot to CD by pressing Apple + C and target selection Ctrl + S. It won't boot. I finally try the Apple + V and there's many yellow line (errors!) came out and some of it is like this:
"Failed to load extension com.apple.driver.AppleIntelCPUPowerManagement"
"Can't allocate class IntelCPUPowerManagement"
"Failed to load extension com.apple.USBUHCI.iokit.ioahciserialatapi"
"Can't allocate class USBUHCI"
I wonder what the h*ll is going on, I'm guessing something wrong with the logic board since I'm waiting for the logic board replacement (RSS symptom) for almost 3 weeks (very very long wait

) but before the Software Update everything was OK although sometime it turn of by itself (The RSS, again!)
So is there anyone could give me any other way that probably can solve this mess? Oh yes, please don't suggest me to send it to AppleCenter - that's the last choice we have!
I'm in a big depressed now - you see now it's 7AM I could not sleep since last night

Thanks in advance.
