MEMORY_MANAGEMENT (1a)
# Any other values for parameter 1 must be individually examined.
STOP 0x0000001A: MEMORY_MANAGEMENT
Usual causes: Device driver, memory, kernel
No misbehaving drivers are showing in your logs:
Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours, it
will make the system bit of slow and laggy, which is to be expected:

Before enabling DV, ensure that you create a System restore point.
If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Update your driver:

Creative Worldwide Support
I would also uninstall Norton Utilities 16 then :
Run SFC to check the integrity of all Windows 7 system files:
Click on the Start > Type in search
cmd
Right click cmd at top and Run as Administrator
Type
SFC /scannow at the prompt
(Note: there is a space between SFC and /scannow)
:ar: http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html
Also Run chkdsk /f/r in an elevated command prompt.
Click on the Start > Type in search
cmd
Right click cmd at top and Run as Administrator
At the command prompt please type:
chkdsk /f/r
(Note: there is a space between chkdsk and /f/r)

Your crash dumps show possible Memory issues:
Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes:

Tip
Run these tests overnight
I still believe you need to install Win 7 SP1 to progress.
