Battlefield 3 crashes and freezes computer

Okay, so I've been playing BF3 for about 5 days, but it has been really hard since the game crashes and freezes my entire computer. I am able to play most games with ultra high quality and play with aroun 50 fps. The campaign of Battlefield 3 works totally fine, but when I play online, the game crashes. This mostly happens when switching map after a match is over, but sometimes when in game. I've been playing other games and i've had the same problems with a few other games as well. I have the latest driver for both the soundcard and the graphicscard and also DirectX. After updating this, the problem got solved on MW2, but it continues on BF3. I've seen a **bleep**load of threads about this problem but haven't seen any solution, I've tried to contact EA and Dice but haven't got any reply yet. Anyone here that could help? 

The "symptoms" of this crash is: 
The screen turns black 
A "BRRRRRRR" sounds is coming out of the speakers (sometimes) 
Computer is completely frozen, requires a hard reset 



Computer specs: 
Intel Core i7 4770K 3.5 GHz Quad Core 
GeForce GTX 770 2TB 
16GB Ram 
700W PSU-Effect 
Asus Z87-a (Motherboard) 



Last crash, I got a warning pop up saying: 
DirectX function "GetDeviceRemovedReason" failed with DXGI_ERROR_DEVICE_RESET: Device reset due to a badly formed commant.. GPU: "NVIDIA GeForce GTX 770", Driver: 32049
