BSOD - Inaccessible_Boot_Device - stop 0X7B error (W2K Server)

I keep getting the above error on startup. Even once I switch to safe mode the error appears.
During a reboot the server appeared to lose the Smart Array Controller (Compaq 532) & requested for a driver on startup. It appears that the incorrect driver was installed resulting in this error.
I have tried a repair - F6 (install SCSI driver) but the BSOD keeps appearing.

Appreciate your help on this as this is a critical server.
Thanking You.

you will have to remove all the drivers from the windows\system32\drivers directory -- and the INF and PNF files from the windows\inf directory to totally get rid of the old drivers,  THEN, when you have done this, and assuming the new drivers are on a floppy, boot to CD, press F6 several times, and with the floppy in the drive, it will read the new files.  Then go through as if you are installing the OS again, BUT, at the screen where it finds the existing OS, press "R" to repair the installation, do NOT press ENTER!!!!
Update all firmware by downloading a firmware upgrade CD free from, support and downloads..

It this does not help call HP Support, they are the best at solving problems with Compaq/HP hardware...
Sounds like a hardware problem to me, I hope it's still under support.

Can you give me the parameter it shows on the screen?

1,2,3, or 4.

This will help to identify the issue, and the cause.

The parameters are as follows:

Try the last known good cofiguration from the startup menus. Did you create a secondary hardware profile within the OS?
Another suggestion is to boot from a secondary OS, like Windows PE or BartPE and run a chkdsk /r on the drive in question.
If neither of the suggestions work, you will have to follow the recommendation of Scrathcyboy to remove the old drivers and install new drivers without the use of the OS.
