I have been getting a BSOD with Stop 0x00000019 with the parameters of
(0x00000020,0xE38B5740,0xE38B5760,0x0C040201).   I have not installed any new hardware in the last 3 months and this has only started in the last week. 
Any suggestions as to what is causing this??

Thanks
It could be due to several hardware ISSUES...failed and/or failing.

Can you boot into Safe Mode?yes no problems.   When I look at the Device Manager, there are NO entries with the yellow question mark.

OKAY...our next step will be to test the memory...okay?

Are you familiar with how to remove memory modules from the motherboard?

What we want to do is try one stick at a time to see if it could be a memory stick causing the issue.

With me so far?There is only one memory module and yes I have taken it out and RESEATED it.Any other suggestions?

ThanksSorry...

I'm at WORK right now, but will be back on in about 2 hours...okay?  In the meantime, someone else may be able to help.This particular Stop error code is referring to a BAD_POOL_HEADER.

There is a bug checker for this...and it is hardware related...more than likely a driver issue.

There is a bug checker:  Bug Check 0x19: BAD_POOL_HEADER

However, it doesn't provide the particular parameter you have supplied us with.

Below is some information you may find useful and hopefully correct the issue you're facing.

Personally, I'm running Vista and don't have privy to an XP machine to help you out.

I did find this for you at Google Groups:

If you have a Minidump file: Windows/Minidump/Mini082108-01.dmp, then you
can debug the system. Instruction here:

Use the !analyze -show (click on the blue text) command.

Look for the MODULE_NAME and IMAGE_NAME HEADINGS. This is the program that
caused the error. Sometimes when it's a device driver it means that that
device is causing the BSOD and by disabling it or updating the driver your
system will run stable. If you don't know what device that name relates to
then Google it.
