Multiple BSOD`s / Crashes / Unexpected Restarts

My Computer started experiencing BSOD every once in a while about 3 weeks ago, and it has progressively gotten worse, to the point where it is crashing/restarting 10+ times in a day. I have not made any hardware or software changes during this time. The most recent BSOD’s error gave: DRIVER_IRQL_NOT_LESS_OR_EQUAL and PAGE FAULT IN NON-PAGE AREA. I recorded a few of the file names given as causing the BSOD: ntoskrnl.sys, win32k.sys, dxgmms1.sys.
I have attached the BSOD Dump & System Files. Please let me know if you need any additional information.

Specs:
Windows 7 Professional 64Bit, which was updated from my previous XP OS
Intel Desktop DH55TC Motherboard
Intel i3 processor
8 GB Dual-Channel DDR3 RAM (Upgraded from 4 a year ago)

Hitachi 750GB Hard drive

Please let me know if you need any more information.
Thanks!

These are all over the map. Some hardware some soft. If I we you I would remove Norton AT LEAST TO TEST. It can be responsible for these kinds of crashes. After its replacement we can investigate further.

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

I have removed Norton. However the computer is still really slow, it is unable to have music running (stuttering).

If it is still crashing upload the DMPs, if it isnt try running SFC.

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

It is still crashing. The last few times it has crashed, it reboots and crashes in the rebooting process 2-3 times before it loads windows. Attached are the new DMP file's.

I ran SFC, and attached the logs. It said it didn't find any problems.

Three of these were Related to HDAudBus.sys High Definition Audio Bus Driver v1.0a Windows from Microsoft.

Since you already have SP-1 installed you may need to do a repair install as I dont think you can re-install the HD audio by itself.
