Random Blue screen of deaths

[disruption]

I am experiencing random BSOD while gaming and browsing the internet. I get different stop codes each time. I have ran Memtest on both sticks of ram and they both passed.

I have checked the hard drive and no errors were found. I have updated my graphics card drivers, my lan drivers and deleted daemon tools drivers and I am currently looking for a way to delete AVG off my computer as it keeps re installing itself when i restart the computer.

My computer is custom build about 3-4 ears ago. It consists of
-Hard drive M4a77td pro
-4 GB Ram
- amd Phenom II x4 840
- Nvidia Geforce GTS 250

I will attack som dxdiag logs and somescreen shots of bluescreen view results.
Okay so i cant attach any files to this post.

Try to restore it to an earlier state when your pc is in good condition.I think Avg has a problem with somthing.Always back up your files Or creat a system image for this type of situation.Use Comodo cleaning essential for virus check.
