Yes! same problem here!
I found a fix! I, as you, updated Nvidia drivers last night.
Go to control panel
choose hardware and sound
under devices and printers, choose device manager.
look for your graphics card under display adapters. right click and choose properties.
on the driver tab, choose roll back driver.
it should freeze for a sec, and the screen might turn off and on again. but when it's done (it lets you close the window), it should all be good. Probably don't even need to reboot.
Good luck!
This problem has just started to happen. Tekkit (and presumably all modpacks) ran fine last night. Today, I updated my Nvidia GPU and swapped from the 32 bit java to 64 bit. Upon launching, I found I could not launch any modpack what-so-ever. The launch would hide itself and after a moment, it would come back, having not even launched Minecraft. Vanilla and optifine work well, if that helps find the problem.

If I need to put anything else here, please ask and I will.
Thank you.
