BSOD While playing video, games and randomly

[redguy22]

Hi there,

Ever since last friday I have been getting BSOD. My occured while playing lotro (Lord of the rings online, mmo) and while playing windowd I tried to play a youtube video. Which has never given me any problems before. Also msn and some other firefox tabs were open.
Then saturday and sunday more BSOD came in. During browsing, during doing nothing, on the windows inlog screen. I can't really put my finger on it. Putting load on the system doesn't trigger it, nor does firefox, lotro, seems a bit random.
Only software stuff that changed since friday is a java update, daily Avira anti virus definitions update and I installed guild wars 2.

I tried to look at the bluescreens logs myself, but I really have no clue what I'm looking at, so if you could check for me that would be awesome.

System:
Windows 7 home premium x64
Intel core 2 E6600
4 gig of DDR2
Nvidea geforce 8800 GTS with latest driver I could find
All the windows updates installed

I'm new on here, but I ran your tool to add all my system info and put in in .zip which I will attach to this post. Let me know if it's not correct.

Oh and I would also like to add that I checked for malware and virusses. Found nothing.

And another adition. 2 more bluescreen since I posted this all. And I ran a prompt sfg scan to check for corrupted windows files, which came back clean.

One BSOD regarding 0x03b SYSTEM_SERVICE_EXCEPTION
And a HDAudBus.sys+115a7 which is the audio driver I was told?

Any other clue's from folks with decent knowledge? As I really don't have a clue what I'm looking at other than wiki/forum/google info I'm getting.
