I recently undervolted the i7-4790k in my laptop in an effort to reduce the temperatures using Intel Extreme Tuning with the Dynamic CPU Voltage Offset is reduced to -26mV.
After running Prime95 and the Intel stress tests, and several hours of gaming over the course of a few days afterwards all seemed well, but when I switched it on a few days ago, about one minute after bootup I got a BSOD. Using Window's debugging to analyse the error file it came back with this:
Use !analyze -v to get detailed debugging information.

*** WARNING: Unable to verify timestamp for CFRMD.sys
*** ERROR: Module load completed but symbols could not be loaded for CFRMD.sys

Probably caused by : CFRMD.sys ( CFRMD+9b89 )

I believe this may have been a problem with Comodo, but I'd like to know if it's possible there were underlying factors cause by the undervolt (I appreciate it's probably difficult to tell), as I said this has been the only BSOD.
In addition, when I started it up this morning the laptop appeared to turn on, although nothing appeared on the screen for about 10 seconds then it switched itself off.
Is this something I should be worried about? Would it be worth bringing back up the voltage or would it be better to persevere and see if it occurs again?
I almost always use the laptop plugged in, but on both these occasions it was on battery power if that's any help.
Thanks for any advise you can give guys!
