many random bsod's 0x0000003b. 0x00000019. 0x0000001a

Hi!

I'm getting many random bsod's on my computer.
system_service_exception and irql_less_or_not_equal is common but also other things.

0x0000003b
0x00000019
0x0000001a
0x00000024

What i got figured out is that is has to do with some driver bug or similar.
i have tested my memory with win7 tool for aboute 50 rounds and no problem was found.

I got so many crash dmp files so i dont know how many i can post so it not will be to many. i send 5 om them to start with

First time im here and i realy need help to solve this because it happens several times a day now more adn it kill's me Please help. Sry 4 my bad english.
