[SL freezes while "loading world"]

It's happeningto me, too. Weird thing is my alt can log in fine. Using Firestorm most recent viewer for BOM.   

[After downloading new nvidia drivers, my pics are grainy and pixelated.]

I uninstalled and reinstalled drivers. I updated to newest firestorm viewer. Nothing is working. I've checked all my settings and they are all up to the highest possible. I'm not sure what I'm missing or what happened. I'm wondering if possibly my nvidia settings on my laptop are messed up after last driver install but not even sure how they should be set. Appreciate any input. I have obligations I don't feel like I can meet due to this problem.  =\    GeForce GTX 670M graphics card if that helps. ty!
