Crash since last update when downloading games with Steam
Original message was deleted
SThat sounds somewhat simiar to what I'm experiencing. Did Steam give you a Disk Write Error and then your desktop does black and apps close? Power button just gives you text that shutdown failed?
KDownloading games uses a lot of CPU, make sure your power supply is adequate
KYou can do ujust logs-last-boot to get system logs up until the crash
KBut if it's hardware related it may not reveal much
