Windows Shuts Down Unexpectedly

typically i would point the finger at:
overheating or
spyware

look if any of this helps :  http://answers.microsoft.com/en-us/windows/forum/windows_7-system/random-bsod-with-new-pc/4af02ea3-6a11-4066-8f85-acfeba3d86b2

perhaps your power supply isnt large enough to handle whatever you have in your system? which may well fit with your previous bsods

Have you tried reseating the memory modules in your machine / Ran some memory tests to make sure there is nothing wrong with the memory as these can lead to intermittent blue screens.
If you have two sticks, remove one of them and keep running the machine, does it blue screen after few hours or days? Then swap them around, does one cause them to blue screen?
Or if you dont have two sticks, see if you can borrow a stick of memory to test for a while.

Further to that have you updated all your drivers on your computer, the last thread seemed to point to the network drivers at first.

This seems to point to pci.sys.
I would update the following drivers:-
Chipset
Network Card
Video Card.
Sound Card

If that fails, look at your internet security. If you are running Norton, remove it, run their cleaner and try a free product like avg.
If that fixes the issue, uninstall avg, run the avg cleanup tool and try reinstalling your Norton.
If it stars again, then remove Norton and use something else.

This file can be spyware so make sure you run malwarebytes free scan

Reboot computer and check.

If nothing works then backup all data and do a clean install of windows 7.

After reinstall install all updates and check whether u get any bluescreen.

Ok I renamed the file to rt64win7.old, just haven't had time to mess with it recently. Oh an I have the most up to date driver.
111211-15241-01.dmp

New dmps point to the same file Rt64win7.sys

Backup your data and do a clean install of windows 7...install all updates . If you get a bsod after doing a clean install then it might be a Hardware issue..Ethernet chip might be bad.


Is this a dell computer....if yes then run dell diag on ethernet.

you can test if it works correct when booted from a live knoppix cd : ftp://ftp.gwdg.de/pub/linux/knoppix/KNOPPIX_V6.7.0CD-2011-08-01-EN.iso     
you should be able to browse the net

Ded9 has been helping me throughout this entire scenario across two questions.  The computer still shuts down but after what I now believe to be the correct realtek driver I think we are in a much better situation than before.
