BSOD mostly random, ex. error SYSTEM_SERVICE_EXCEPTION

Normally I can solve these issues myself, but I am at a loss here.
I have been experiencing random BSOD for a month or so. Before that, it was completely stable since about a year ago when I built it.
It is mostly random. Happens at idle. Also seems to happen frequently when browsing web or listening to internet radio. I have seen different error codes and googled every way I know how. Nothing fixes it. Hopefully, I have followed instructions and can provide what you need to help me. Thanks in advance for any help you can provide.

Is Windows 7 64bit
I built the system about a year ago
i7 2.80 GHz CPU
8GB Corsair Dominator DDR3
Asus P6T6 WS Revolution MB
Asus ENGTX470 Graphics Card
1 TB Western Digital HD, no RAID

Also want to add that I have done all MS patches, and verified all device drivers are up to date.
I uninstalled Symantec Enterprise Edition and loaded MS Security Essentials.
And various other things.

Your Symantec/Norton security suite is the cause, it should be reinstalled
Always use the latest versions

Hi, I uninstalled Symantec earlier today. It worries me that you see it still. I do not see any associated Symantec apps in installed programs.
I assume this bugcheck was from earlier today before I uninstalled. I am still seeing BSOD. At least 2 since the SYM uninstall.

I have tried to look at the dump files and its hard to make sense of

I see svchost.exe, fileinfo.sys, ntfs.sys, ntkrnlmp.exe etc.

This has happened 5 times today.
Any help is much appreciated.

The attachment I applied in my first post has all of these dump files.
I ran memtest+ over night for almost 12 hours with no errors.

Starting today, I am now seeing a popup message that
Windows Explorer has stopped and is restarting, the screen refreshes and then all appears to be OK.
I do not really want to wipe the hard drive and reinstall the OS. Please Help.

Run SFC, it will fix any corrupt system files
SFC /SCANNOW Command - System File Checker
Run a scan of Malwarebytes

I figured out the problem. I uninstalled Norton Enterprise security and installed MS Sec Essentials. No more bluescreen. The issue with windows explorer crashing was resolved after MS updates were completed.
Thanks to all for the suggestions.
