Ever since I got a new OS onto my SSD, BF3 wont launch.

It says "Initializing.." for ages, and then I check task manager and the bf3.exe is running but no window and in origin it says I'm playing BF3. I'm baffled and so is the origin support, they just get copying and pasting me horrid procedures and I just told them not to bother helping me anymore.

Anyone have any ideas besides the obvious reinstall? (Which I have done)

what other procedures did you do besides reinstall? so people don't just repeat what origin support told you.

Delete Temp files - %temp%
Delete all .exes besides ones needed to run origin and the game. And the obvious important ones.
He told me to restart my modem. Laughed at that.

Origin & BF3 in firewalls allow list? (windows firewall included)

UAC Enabled? try disabling it.. fixed a similar issue i had.

Both off and don't use anti-virus.

Bad luck
