Each had the same result, shutting off a few mins into the test. While the computer was running, i made sure all the fans were running, no capacitors are leaking, and speed fan shows my cores at 47C and 50C, at idle. 60C and 67C with about a 35% load. I saw 70s while it was still loading some windows programs. It has been saying on for at least a half hour now at idle on the desktop. Could it be over heating?
Did you plug any case fans you might have disconnected back in? While those temps are pretty high, 70s shouldn't shut the computer off. It would be kind of hard to tell unless we knew the temp just before shutdown. The Memory diag probably heats the CPU a bit too so now I think its kind of a toss-up. The best thing to do now is get memtest86 going. Even with that though, an overheating CPU can cause memtest to show errors in the ram if the cpu gets too hot.
Also, I am wondering, over the years you have had this computer, did you ever go around in the bios and change any settings, not really knowing what you were doing? besides yesterday of course... There are a couple settings in there:
CPU Thermal Monitor 2 (TM2)
Enables or disables Intel
CPU Thermal Monitor (TM2) function, a CPU overheating protection
function. When enabled, the CPU core frequency and voltage will be reduced when the CPU is
overheated. (Default: Enabled)
CPU EIST Function
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading,
EIST technology can dynamically and effectively lower the CPU voltage and core frequency
to decrease average power consumption and heat production. (Default: Enabled)
The default for these is enabled, and they should be still enabled to prevent overheating of the cpu. I'm pretty sure its safe to say if these are on, you wouldn't be overheating.
IF ANYONE HAS ANY INPUT ON THESE SETTINGS AND INTEL CPUS I WOULD APPRECIATE IF YOU COULD POST AND TELL ME IF THIS IS CORRECT. I don't work on many custom intel computers...
Regardless go check to make sure these are on, they are under Advanced Bios Features from the main menu.
