Hi Michael,

I'll be in contact be email.

Thanks for the link to CPUID Hardware Monitor. Very useful.

On the slightest chance this is of benefit to anyone else:

As expected, the Memtest86+ tests resulted in a pass with zero errors.

According to the CPUID HM, CPU temp was around 30 degC, while GPU temp was at 86 degC. (My Mobo has onboard graphics and only a CPU and PWR supply fans due to small case size.) Re dust, there is a little, but I did already vacuum out a LOT of dust a few months back as the entire PC kept repeatedly crashing. Since then I've had no system crashes - and MoI v2 is stable under the current (relatively hot GPU) conditions.

As an exercise, I just rigged up a 2.5 cu.m/min (88 cu.ft/min) fan to blow into the open case. GPU temp is now 38 deg C, while system and CPU are 25 and 21 degC respectively. Left idle, at the lower temps, MoI v3 continues to crash however.
