Vista - Blank screen on boot?

Whilst booting my vista 64 home premium I have a blank (black) screen which stays for about 30 seconds (or longer) between the green loading bar and vista logo centered in the middle.

Is this normal?

What is the boot sequence - v. rough times would be good.

If its not normal how do I get rid of it - I have a couple of PCI cards that don't have drivers that I've disabled in the device manager but I might try taking them out to see it makes a difference.

Any information at all would be greatly appreciated

Hi,
Open SYSTEM CONFIGURATION in Administrative Tools. Make sure that under the GENERAL tab, you have NORMAL STARTUP dotted. Under the BOOT tab, nothing should be checked. Change the TIMEOUT time to a lower # if you want to decrease the time Vista waits on you to do a boot option. (ex:Safe mode, boot from cd, etc...) I use 15 secs. To short & you won't be able to hit the key fast enough.

Hope this helps,
Shawn
