I had (yes had) same problem but for me it was 1-2 minutes, took me over a week to get it figured out.
For me it could have been one of 3 things.
First I found I had a virus, once I was able to remove that, the problem stopped, for a week, then came back and doing the same thing again, I went and got another virus checker, and found there were folders that were supposed to have been removed/deleted, but were not, They were of other mmo games that sucked, more kiddy like, not my kinda game.
that was 2 of the things I did, the third, was also my first, but had malware at that time, it was my rendering Device, prior to what ever one I chose, never the fix, but after removal I tried those settings again, this time success.
1.check for virus/malware
2. try the different rendering settings in "Settings" on the login screen
Not sure that will fix your problem, but it did for mine.
Good luck .. took me 10 days of having drawbacks /shakes / sweat to get my AO flowing through my blood stream again
