BSOD Frequently After starting Windows 7 x64 error 0x00000050

Hi everyone,
I am a first time poster.
Currently I am experiencing a major issue with my computer. I will start my computer up and I get a BSOD within about 10 minutes. It has happened 10 times already and I have no idea how to fix it. I have read numerous forums, tried updating graphics card drivers, hard drive drivers. I have performed disk check and run a memory test with no errors. I am not sure if it is a hardware fault or other. The BSOD also occurred while I was in safe mode with netowrking turned on. I have tried doing clean boots and even tried disabling my graphics cards, network adapters and audio drivers. All that I have tried so far has had no effect so I am posting here to try and see if someone could help me.
I will post the dump file which is always the same every time the BSOD happens.

Thank You.

==================================================

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.

If you are overclocking STOP


We could also use some system information, which you can get easily by running msinfo32.
To do that go to start>run>type msinfo32>enter

When it is finished running go to file>save>name it and upload to us here.


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.
