[CentOS] I need help with CentOS installation on a Core 2 Duo Laptop

Hi,
I tried this option "linux acpi=off pci=nommconf" as well but the
problem is when I use this I can install the OS but when try to boot
on to the OS it's hang up on the boot up progress bar screen of the
CentOS and I can't do  any thing. So I checked it with the text mode
loader it was the same problem can any one help me to over come this.

Thank you
