BSOD & Crash to Desktop while playing games or watching videos

[Vlday]

Hello everyone,

I hope I can find some help here with these crashes I have since several months now.

While playing games like CS:GO or H1Z1, I have a lot of crashes to desktop and sometimes BSOD. The BSOD can happen also while watching streams & listening to music. So far, I had these ones : 0x1000007E / dxgmms1.sys+1DFA5 / 0x0000003B / atikmdag.sys+C4DE0.


I think I tried everything in my knowledge to solve the problem but it still didn't resolve the problems. On the hardware side :
- Switched the memory sticks ;
- Switched the graphic card (my brother has the same one as me and it never failed him. Still it didn't resolve the problems on my computer) ;
- Switched to Marvell SATA controllers then to the 3Gb Intel controllers ;
- Used a USB sound card thinking that it may have something to do with the audio on the motherboard;
- Changed the graphic card slot to the PCI 8X.

On the software side :
- I reinstalled all my drivers using the suggestions made by this site : Easily explore your PC & using also some other softwares like SlimDriver ;
- I formated & reinstalled win 7 on my SSD ;
- I installed win 7 on my HDD thinking that my SSD was the problem ;
- I uninstalled the KB3022345 and KB3068708 updates ;
- Uninstalled my antivirus (MSE) & disabled my firewall ;
- Used the sfc /scannow command without any problems detected ;
- Run malware bytes & antivirus softwares (mse, ESET);
- Run software like "fixmypc" & cccleaner;

After all these actions, my pc still crashes a lot, especially the "crash to desktop" ones. I really hope someone can help me out here !

And I just had another BSOD, this time it's a "Memory Management" one. Here are the details of this one :

On ma-config.com, it says that the source of the crash is :

Any help guys ? Does all these crashes have something to do with my motherboard ? Should I change it (the only thing I didn't change is the MB & the power supply).

Many thanks.
