Black screen and frozen computer on load.

op post your pc specs in here also you can try this:

Black Screen ? This is a DirectX11 problem, turn it off, and you will be able to play again.

1) Create a text file inside your BF3 dir user.txt and type RenderDevice.Dx11Enable off
2) Close it
3) Rename it to user.cfg

No more black screen bug between maps.

or

do not know if it works, is an old fix. saw in the forum somewhere
if you make for it at your own risk

also found this:

FYI - Possible Fix for some with 64-bit Win7 and new BF3 Patch***

My brother recently downloaded the patch and he would play perfectly fine before, and now it freezes every time he tried to load a game (loading black screen) then takes him back to the battlelog.

FIX:

I just disabled UPnP in the setting for his router and it worked immediately after that.

So for those with mostly Linksys routers.
Open up your internet browser
type 192.168.1.1

username: (default username is left blank)
password: (default pw is admin)

Administration tab> Disable UPnP
Save.

Done. Let me know if this works for some.
