Asus A8N SLOOOW bootup 1011 BIOS 6.65 nforce 4

Can someone please help me as I've ran out of ideas as to the cause.

I've done a clean install of XP (32 bit) on an ASUS A8N (Non Deluxe) mainly to use the new 1011 BIOS as I'll be upgrading my CPU in the near future. I've also installed the 6.65 nforce 4 drivers off the ASUS site which they insist you install if you upgrade to the newest BIOS and I'm using 7.77 forceware for my 6600GT gfx card. My system was running fine with no problems whatsoever when I was running 1008 BIOS and 6.53 nforce drivers and the same 7.77 gfx drivers so I know the hardware is working correctly.

Now though, when it gets to the startup screen, the blue scrolling line just keeps scrolling. No error messages, when it does eventually boot in to Windows (after numerous manual reboots) there's no error messages in the event viewer either. I have no conflicts and device manager shows no problem devices. One thing I haven't installed is the nvidia IDE drivers as I have had nothing but problems with these in the past and the Microsoft ones work just fine. I know if I went back to 1008 BIOS and 6.53 drivers, it'll work OK, but I shouldn't have to. I haven't done any overclocking either.

Can anyone give me a solution? Please? My system specs are;

ASUS A8N Non Deluxe Mobo
ASUS EN6600GT gfx card
2 x 80gb hitachi SATA drives in RAID 0
AMD 64 3200+ Winchester
LG 4163B DVD Writer

If anyone needs more information to help me, I'll supply it on request. Thanks in advance!
 
The described symptoms point to a driver/hardware recognition problem. Rethink the drivers you have installed and see which have been missed. Maybe those nvidia IDE drivers are necessary for the new bios. Also, you may wish to use an older BIOS version since this new 1011 version may may contain a bug or two that may be creating your problem.
 
I've doubled checked the installed drivers and I haven't missed anything. I'll try a previous BIOS version and IDE drivers when I get home from work later. Thanks for the suggestion!

In the meantime, does anyone have any other possible solutions?
 
I've managed to find the solution so to help anyone else with the same problem, this is it. The reason my (and numerous others I found after doing lots of research) took an age to boot is down to the Nvidia Sata controller driver enabling NCQ on my hard drives. Even though my Hard drives are NCQ compatible, it is a well known issue with the Nvidia driver.

To prevent slow boot up and possible data corruption, just turn off NCQ in the driver properties in device manager.

Go to device manager, look for the SCSI and RAID controller entry and double click the NVIDIA nForce4 Serial RAID Controller, click the Primary Channel tab and untick Enable Command Queuing. If you have a RAID setup, do the same on the Secondary Channel and then reboot.

Since I did this, I've had no boot up issues and no event 51 errors in event viewer.

I hope this helps anyone with the same problem!
