Details about the crash:
While ingame on skyblock, noticed sudden repeated FPS drops, and gameplay "stutters", started off short duration, getting longer until complete freeze of PC. After hard reset of PC, game crashes on startup - displays white Mojang screen but crashes at main menu.
Have googled and noticed another thread over on main forums talking about a similar crash with Itemducts being an issue, and I had been placing some before the crash.
