Windows won't start after replacing CMOS battery.

I have an ASUS (not sure which model) that has Windows Vista Home (Premium I think, but possibly Basic).  I have had some issues recently with my computer not keeping the BIOS settings when it restarted and I had to keep changing the HD priorities so it booted from the right one.  The clock was always off after this as well.  So, I decided to replace the CMOS battery.

After I changed the battery and started up the computer, I got a message that Windows couldn't start and it gave me the option to try again, normally or in safe mode, etc.  It also said, if it wasn't the first time it happened to use my recovery disk and use it to repair windows.  If I try to start windows normally, the computer restarts and then the same message comes up.  If I try safe mode, it shows the computer loading up the windows components, but then also restarts and goes back to the same error screen.  

When I use my recovery disk to try and repair it, it starts loading up the disk and when it gets to 100%, I get the dreaded blue screen.  This is before I have any opportunity to make any selections or anything.

I've read about changing some Sata RAID setting after a google search, but I haven't been able to find that in my BIOS.

Anyone have any idea?

disconnect all drives except the primary boot hdd   also reseat the memory chips

see if it will boot..

When you remove the CMOS battery it resets the BIOS to its default settings.  This computer may be old enough to have options for IDE or SATA drives, make sure that the correct settings are applied.

What is the model of this ASUS?

I have been trying to find information regarding the default settings for the AMI version 402 BIOS, but I'm not having any luck.  Without knowing what setting options there are I can't help with this.

When you changed the battery did you observe the polarity of the battery when you removed it and installed it the same way?

Look in the BIOS to see if there is a setting for IDE. ROM.  If there is try this setting.

There is an IDE setting, and I've tried with both IDE and ACHI.  

I believe that this should be set to ACHI.

If you have all of your important data backed up to removable media, CDs, DVDs, flash drives, external hdd, etc, you can use the system recovery to return the operating system to the condition is was in when you opened the box.

To do this start the computer, as soon as you seen the Asus logo start tapping the F9 key.  After this follow the prompts to complete the process.

With the computer off press the power button and immediately start tapping the F9 button till you reach the menu which contains Troubleshooting, click on that and then click on Reset Computer.  Of words to that effects.

If you want help with this you can call ASUS support at 1-888-678-3688.

You need to start you own topic in a Windows forum appropriate for your version of Windows.  Provide a complete description of your problem.  It often helps if you post the make and model of your computer.

I have a Latitude 6420 and had to replace the CMOS.

Pretty simple; removed the HDD and Cd drive and some screws.

Put back together and fired up the laptop. NO Windows. Jus the Dell logo and then to recovery.

After reading for hours and hours, figured out that the pins were not making good contact with the HDD.

Really tightened the 4 screws that hold the HDD in the laptop. Problem solved.
