Multiple issues and system crashing

Ok here it is UppIT - Free File Sharing - MEMORY.zip

If this helps , every time I run Ad-Aware program it gets about 15 minutes into the scan and gives the blue screen about the bad kernel and closes.

Ad-aware was directly blamed as the probable cause of that BSOD; please remove it completely.

Other things to do:

Remove Symantec according to these removal instructions: Norton Product Support | Installation and Uninstall

Replace it with MSE: http://www.microsoft.com/security_essentials

Install Service Pack 1: Learn how to install Windows 7 Service Pack 1 (SP1)

Graphics drivers are one thing that are especially prone to causing problems if they have compatibility issues. I see you are using 2006 nVidia drivers, which is a recipe for problems in Windows 7. Install these updated ones: NVIDIA DRIVERS 266.58 WHQL

Code:

nvlddmkm.sys            Tue Oct 10 01:44:34 2006 (452B3342)

If that doesn't do the trick for you, turn on Driver Verifier again, and upload a new jcgriff2 report.

For now, you can turn off Driver Verifier.

I can't find the dump file this time. I had one before that I uploaded. Is it in a folder? Maybe I needto to run the driver verifier again. I am not getting any blue screen. Just frozen up. I ranthe command sfc/scannow and it didn't find anything. System freezes up often when using Windows Media Center.

Dean - no full dump file exists; see the !_kernel_dump_list.txt file.

I see the last crash that was recorded was not a true BSOD, but rather a Kernel Power 41 event:

Code:

Event[97]:
  Log Name: System
  Source: Microsoft-Windows-Kernel-Power
  Date: 2011-03-13T10:17:27.859
  Event ID: 41
  Task: N/A
  Level: Critical
  Opcode: Info
  Keyword: N/A
  User: S-1-5-18
  User Name: NT AUTHORITY\SYSTEM
  Computer: Mark-PC
  Description: 
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

I suspect we are looking at a hardware issue here, but first, I notice the BIOS is 5 years old:

Code:

BIOS Version/Date    Phoenix Technologies, LTD 6.00 PG, 8/11/2005

I couldn't find the BIOS for your board, what is the model of your computer? If you can find an updated BIOS, please flash it.

Onto the hardware tests...

What is the make/model of your PSU?
