After upgrading to Windows 8, my formerly wonderful laptop has been causing me a lot of undue grief. It keeps crashing-- sometimes upon waking, sometimes upon shutting down, sometimes when doing nothing at all. I received the DPC_Watchdog_Violation message, but am unsure as to what this means. I've attached a zipped folder of my minidump files for your analysis. I'd truly appreciate any help you could offer-- I'm going crazy here!
