A lot of blue screens

Hi everybody,

First, I'm sorry for my bad english :D and if I posted in a wrong place.

I searched on the forum for my problem, but every topic has a different program causing the blue screens, so I decided to post a new topic. I'm sorry if I did something wrong.
This is my PC:

Motherboard: MSI P43 Neo-F
CPU: Intel Core 2 Duo E8400 3.00GHz
Memory: Corsair XMS2 Classic Purple 2x2GB DDR2
GPU: Sapphire ATi Radeon HD5830 1GB GDDR5
Power supply: Corsair TX650W
OS: Windows 7 Ultimate 64-bit

This summer my video card has burnt (HD3870x2), so I bought another one plus another 4GB RAM (same model) and a HDD (WD10EARS). After I installed every component, I turned on the PC, but it couldn't accept 8GB RAM (even if the limit of the motherboard is 16GB). I removed the new memory cards and I turned it on again. It worked, everything was perfect. Next day... boom, a BSOD caused by dxgkrnl.sys. I had to restart the PC for many times. When I succeded, I thought the problem was the GPU's driver so I installed the newest one from the producer's site (AMD). It had no effect. I reinstalled the OS. For a few days there wasn't any problem, but when I installed a new game (I don't remember which one), it started again. Many, many blue screens. I decided to stop playing games for a time. I didn't have any problems for 2 weeks, but when I started to play again, the BSODs started to play with me too... I don't know why, but there weren't so many as before. Now, in the minidump folder I have almost 50 minidump files o.O
46 caused by dxgkrnl.sys (STOP: 0x00000116)
2 caused by win32k.sys (STOP: 0x0000003b)
1 caused by ntoskrnl.exe (STOP: 0x00000050)

I have some screenshots:

I'm full of it. Please, help me :(

  1. Anything overclocked on your machine?
  2. I've already tried those things long time ago... I don't think the video card is the problem..
  3. Temps ?
    Monitor with hw monitor -
    Try a bios update, you changed to a newer card..
  4. I was doing that :)) After half an hour of playing Batman: Arkham Asylum. Do I need to check the temps in another game ? More time ?

  5. I dont know at what point is batman intensive, but Your temps seem just fine.
    have you tried with a ram stick at a time ?
  6. And what about the bios upgrade -
  7. No, I never tried any ram stick. Should I ? :D
    How can I update the bios (the motherboard is MSI P43 NeoF) ? Sorry, but I'm a noob :)) If I update it, it will solve the problems ?
  8. Well go to MSI website-
