We seem to have drifted away from the temperatures you reported, if prime95 fails quickly then this is almost certainly an overheating issue
Did you fit the cooler properly, are you familiar with the process and did you invest in some decent thermal compound
I know you say temps dropped after you fitted water cooling but 40+ at idle sounds high to me for water cooling
But that aside if your machine is crashing under gaming then gfx temps need to be looked at also, check gfx fans are spinning freely and clear of dust
0x124 errors are hardware based, although this is not always true it is the place to start
