I keep having this issue.. It is infuriating... The night Windows 10 launched, I was able to boot my PC and play around for about thirty minutes before I went to bed.
Next day later that evening I boot up and it's all good to go.. Using Edge, etc, and then boom it locks up...
I can open CTRL+ALT+DEL fine but when I hit task manager, nothing pops up... When I hit shut down it sits there spinning saying "Shutting down" and goes forever before I am forced to pull the plug... Sometimes when it locks up I can hit the start button or open cortana, but then it starts to lock those up too where the entire thing is frozen up... I reboot again, fine for the first few seconds opening and closing stuff to test and boom, same thing, locks up.
Any ideas? at this point my computer is practically a paper weight!!!!!!!!!!!!!
