Aero BSOD.

[smn]

I installed windows 7 professional just today and my system repeatedly crashed after enabling the aero theme.
A few things I've tried for this are VGA driver update,Virus scan and repair( I am not 100% sure if I performed that correctly) and the problem persists.
My system specs are as follows:Nvidia 8800GT alpha dog,Gigabyte X48 DS5,intel Q9300,thermaltake toughpwer 600.The antivirus I use is avast basic(the free one).
I've read some guidlines concerning the DMP file while asking for help but I didn't pretty much get what I had to do so I could use some guidance on that.
Thanks in advance.
As I just noticed the system crashes after viewing videos as well(it did that when I was on XP as well).View attachment 99682
Hope I posted the correct file if not just inform me.

At least could I know what is wrong with my post?
->(before/after editing)
The performance report is in greek so it's uninformative.Amongst others it evaluated my VGA,CPU,RAM,HDD performance as low.
P.S apologies for the numerous edits.

The uploaded file does not contain all of the reports that we use.

But, the one memory dump included is a STOP 0x116.
