iPC 10.5.6 Final only starts sometimes....

Hp t3730.sc AMD Athlon(tm) 64 X2 Dual core Processor 3800+ 2.00 GHz 3GB ram Motherboard ASUS A8M2N-LA Geforce 7500 le grapihcs card that about everything say if you need more info

I think it is something wrong with the shutdown because when i'm in mac and use shutdown and then try to start it again i get first apple screen then black and then blue and last a black screen with a cursor in the corner and can't move it. When i use Restart in mac everything works well so i guess something is wrong with the shutdown part.

Yeah i hate it. I hope someone got a soulotion...

I have tried if it was anything wrong with the mac shutdown put if i log in to windows and shutdown and then start computer again and boot in mac i get black screen. So only when i log in windows and use restart is the only way to get into mac…

okay i have got the Shutdown bug fixed i installed another Nividia drive it was Nividia 7600 GT something and know the only problem is the screen resoulation but that will i probaly get to work

ok have you tried to install with no drives and then run Nvidia installer 3.0? I did that and i chose the NVinject 0.2.0 instead for 0.2.1 that is in iPC 10.5.6 final and that worked try it out if you haven't.

God luck

Please post your complete Hardware.
Furhtermore, let it boot into black screen once, the boot it using your method and hit the following on Terminal: "cp /var/log/system.log ~/Desktop/system.log" (The ~ you can get by WindowsKey + N) and attach the file, which appeared on your Desktop. Maybe that will help us analyzing your problem.

As I wrote above, that log file might help to detect your problem...

Well, you know what? I too have that problem with iPC updated to 10.5.8. Everything works perfect but to boot correctly I have to boot into Windows then restart and OS X works great, otherwise if I boot it first I get stuck in a blue screen after the apple logo. I wonder what is causing this...

@eskild12I think it is something wrong with the shutdown because when i'm in mac and use shutdown and then try to start it again i get first apple screen then black and then blue and last a black screen with a cursor in the corner and can't move it.

You might try to use this Utility, to shutdown your computer:
pcwiz computer.com/downloads/pcwizshutdownrestart.zip

Imkantus, I used the utility but it did not solve problem. I also tried with the OpenHaltRestart kext. None work. On a side note, I revised the log file and found this line which I think has something to do with the problem (not completey sure though):

com.apple.PCIESlotCheck[107]: [PCIESlotCheck] Error reading PCIE lane config. Unable to check PCIE slots for changes.

Just an update.

I changed the video card (GeForce 8400 GS) to a Radeon x1650 Pro. Problem is still there. QE/CI, resolution, everything works. But when I hit shut down, then turn on the PC and let OS X boot, it gets stuck in a blue screen right before going to the desktop. If I boot Windows first, then reboot and let OS X boot, OS X boots perfectly. It seems the problem is with the shutdown. On a side note, if I remove the video card drivers, OS X always boots correctly, even if I shut down. So the problem is related to shutting down and having the card activated (meaning QE/CI/Resolution).

Have tried with 3 different video cards. For now I give up. If someone has a clue as to why this happens (I have no idea) please let us know. I have searched the net and it seems no one else has this problem.

@eskild12okay i have got the Shutdown bug fixed i installed another Nividia drive it was Nividia 7600 GT something and know the only problem is the screen resoulation but that will i probaly get to work

Glad its working for you. Here it isn't. And I don't think it is the card since I tried with an ATI and it does the same thing. I've also tried many drivers with no luck.

@eskild12ok have you tried to install with no drives and then run Nvidia installer 3.0? I did that and i chose the NVinject 0.2.0 instead for 0.2.1 that is in iPC 10.5.6 final and that worked try it out if you haven't. God luck

Tried. Didn't work. Forget it, I give up. Been trying for a week.
