Heya folks. Just wanted to give you the head's up in case your G75 notebook starts shutting itself off, immediately, upon performing certain actions, such as removing a USB device. This suddenly started happening to me, and I narrowed it down to the following "recommended" update.
Upon removing this update, my issues disappeared.
Update for Windows 7 for x64-based Systems (KB3118401) (Published Mar 8, 2016)
[h=1]
Update for Universal C Runtime in Windows
G75VW-DS72 w/ Core i7-3610QM, 16GB, GeForce GTX 670, 256 GB SSD, 17.3in Full HD (2D Matte), Blu-ray Writer, Win 7 Home Premium 64-bit
