Multiple errors after booting up! What do I do

NFORCE6M-A
NFORCE520LE
IDT HD 6-channel HD audio CODEC
Realtek 8111B Giga LAN
Nvidia 8400GS
AMD BE-2300
OCZ DDR2 800 Ram
Maxtor 320GB HD PATA

lanxxx,
Thanks for the reply. I tried going back to diskutil from the boot up disk and tried both repair and verify disk permissions. It didn't fix it. Are these all driver issues? My LAN works but no sound. I don't know if my XFX Nvidia 8400GS is fully functional. From my specs in the second post of this thread, does it look like I should be able to find the drivers for the LAN, Sound, Video card?

What should I do to correct these errors? I am happy though. I have been trying for 2 months to get this to work and this is the farthest I have got.

Before you do anything else try repairing permissions

yazyazoo just correct permissions for all of these files. that should help u

either open disk util click on your hard drive in the right hand side window and click on verify permissions
or

sudo -s 
"input your password"
/Volumes/"name of your hard drive"/System/Library/Extensions chown -R 0:0 *
/Volumes/"name of your hard drive"/System/Library/Extensions chmod -R 755 *

thanx lanxxx, anyways, i rapaired permissions, but the same errors keep on coming. the os does no detect any audio devises, and no modems at all. what should i do?

Tell us your specs and exactly what the problem is

well, the same problem yasyazoo had, when it starts a few errors come up, that Apple AzaliaAudio.kext, NVinjectGo.kext, Natit.kext, IOHDAudioFamily.kext, Apple Azalia Controller.kext. can't be used. and no ethernet card and sound detected.

specs are

amd athlon x2 4200 sse3
asus m2n-mx nforce430
4x 512 kingston memories (2gb)
sata 2 western digital 250gb hard

i've already done that, but the error keeps the same. i have now installed a Genius Sound Maker Value 5.1 PCI audio card, and found some drivers that should work, how do i install them?

it should be just a kext file
That is the soundcard I have,
use this one it works spot on
86.talk talk.net/CMI8738PCIAudioDriver.kext.zip

put it in system/library/extensions
then

sudo chown -R 0:0 *
sudo chmod -R 755 *

reboot with -f
thats it

well thanx a lot dude, i'll try that later cause i'm not at home right now

I have no idea about the soundcard or the graphics card, you'll have to have a check around for relevant kext files, here and insanley mac are good places

well i'v just tried what you told me, but the sound still doesn't work, and the Apple AzaliaAudio.kext errors keep on coming when it boots.
when i put the first line on terminal (sudo chown -R 0:0 *) it ask me for a password, and when i write it i can't see it, is that allright?
i'm doing it right or i have to do something before, like using root user?
should i do something to Apple AzaliaAudio.kext ? what does the -f mode change?
