error code is 7

[stu]

when trying to boot a laptop i am, receiving a error message saying 'program autochk failed to load' then BSOD (c000021a) , so have run HDD memory and both passed tests. so i am trying to restore system files using the WIN XP CD but when ever this loads(which it sometimes doesn't and just goes back to the BIOS screen) I receive the message ' file \i386\halaacpi.dll could not be loaded the error code is 7...' any help would be great!
cheers

There is an article here about forcing a HAL DLL to be loaded.

How to force a Hardware Abstraction Layer during an upgrade or an installation of Windows XP

I have also sometimes put this down to a hard drive controller. Try changing the IDE or SATA type in the BIOS some newer boards are a bit funny with the old XP Cds.

tryed that and it returned 'isapnp.sys is corrupted'

How far into the setup does it get?

Is it possible you have a damaged CD?

or a faulty dvd drive perhaps.
