BSOD at login 75% of tries

About 75% (3 out of 4 ave.) of attempts to start / boot results in BSOD right after I enter password to login into my account. The error codes are different sometimes but only one I could catch = "Bad Pool Error". I have added no new hardware.
Have tried all I could find for a solution without results. Including Pre-boot sys access 4118, sys file check, full scan for virus several times. all the usual.

I have been trying to restore Windows using the built in Dell DataSafe which should be simple but when booting I need to use the F8 key to get to advanced boot options and after trying dozens of times I just can not get the system to go to that screen. It appears that the computer is not responding to the F8 request (also tried F12). I have no disc or original Windows as it was not provided by Dell at the time so can't restore that way.
Note: my McAfee is currently disabled as part of troubleshooting but otherwise always on and current subscription.
When I am able to log on system seems to run OK for the most part but slow which may or not be related. Most attempts to update Windows fail but some do complete.
Problem starter slowly and progressively worse over 2 months. Not sure but I think it
started about time I was loading updates for Windows and loads were failing repeatedly. This feels like a virus or memory leak to me but Using all the tools I have can find nothing. Dump files attached. Thanks for any help.

System was built and purchased direct from Dell. Purchased July 2010. No modifications or upgrades have been done

No DMP files included in upload try this Method


We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.
Please attach the DMP files to your next post not to post one.

If you are overclocking STOP

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

My apologies for omitting the files. Please see attached I believe this is what you need.

These were virtually all related to your McAfee.

McAfee is a frequent cause of BSOD's. I would remove and replace it with Microsoft Security Essentials AT LEAST TO TEST!

http://download.mcafee.com/products/...tches/MCPR.exe

Microsoft Security Essentials - Free Antivirus for Windows

After following zigzag's advice it is recommended that you...

Please run the System Update Readiness Tool (SURT) and then update to SP-1

Is your recommendation to "UNINSTALL" McAfee or is just disabling it suitable for testing?

Uninstalled McAfee problem still exists. New dump attached.

1) My proceedure was uninstall McAfee
2) Install / activate essiantial security
3) run update
4) reboot
5)Windows appears to load and brings up user account screen
6) Enter password to login
7) all apeard normal as desktop populates
8)BSOD after about 15 seconds
9) Auto reboot to user screen then repeats
10)Auto rebooted 4 or 5 times and the loaded normally and can now use computer.
11) Ran OK for a few hours now with no issues, seems to be only on reboot/restart.
I will now restart to see if problem repeats and if it does I will send new dump for comparision.

Good job on the McAfee. Lets do these three things next

1-Run a system file check to verify the OS

SFC /SCANNOW Command - System File Checker

How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7

2-Update these old drivers

How To Find Drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- - The most common drivers are listed on this page: Driver Reference Driver Reference
Driver Reference Table (DRT)
