I'm still unsure to be honest but the errors seem to be either storage or memory related. Now whether it's the storage controllers, HDD, memory, memory slot/motherboard or just a driver is what I'm trying to determine. If the above fails to work try switching on the driver verifier and let's see if we can catch a driver that's at fault. http://www.reviversoft.com/blog/2013/09/using-driver-verifier-to-fix-a-blue-screen-of-death/ If the machine keeps blue screening at start up because the verifier is running with windows 8 pressing the shift key and F8 sometimes works for people. If not use your windows installation disk to boot from.and get into safe mode that way.
